What got me into hifi was watching a midnight session of Jimi Hendrix in a cinema. The panning phased drums in Bold as Love sounded so great, I had to bring that sound home. This new range of speakers are the first I've seen that I think will get closest to that sound. Thanks
Yes but it looks like a stamped steel basket..thats going to resonant all over the place ..cast baskets are the way to go, cost more but worth every penny.
@@MuscleBN It's the same subwoofer they've used for years in their servo sub applications, and it's a cast basket. I have one myself, which I'm actually running in my car.
The best part of high sensitivity speakers is dynamics, the crack of a snare drum, quiet passages that get loud quickly are where high sensitivity speakers shine. Great for rock and roll or orchestral music.
Thanks for the quick follow-up with this! BTW, we redid some SVS Ultra Prime Towers with your components, and like WOW. No more noise, great clarity and it allows us to use a lot more power cleanly of a 300B based 5 watt SET amp that sound deeply wonderful, where it was power and clarity limited before. Thanks!
Interesting design - integrating an MTM "monitor" into a powered sub enclosure - and providing a stand/tower for the speaker - makes a *lot* of sense. You get the bass source integrated into the same footprint, for good phase alignment.
I was so glad to hear you say that you're going to offer this juicy, juicy speaker as a complete assembled unit. If it is what you say it is you'll have a home run.
Just look how pumped you are Danny. They may not be line source but you seem to be so animated. Looks like these old school speakers have your juices going. Great to see. :) Cheers from OZ.
Great to see. and great to see how excited you are with it. Can't wait to see the in room test results / listening session update like u did with the Brute. Congrats on the new Family member
Wow. Those measurements! You’d almost assume that’s purely simulated not actual measurements! …. And that impedance .. could drive those directly from a 80’s Walkman! Speakers are furniture that play music so WAF is critical .. I’d like to see one properly finished and with grilles.
@@MrBonger88Yeah, pair that with a tube based preamp, as that’s what a lot of First Watt amps have great synergy with, and you’d have a great system using multiple sources if you wanted. 👍🔊😊🎶
I always get worked up and excited by the many GR-R product offerings, as each category has unique attributes. The open baffle offerings may be the closest to my audio heading, with Maggies in one system for the past 10 years. I get what Danny is talking about speakers that are fun to listen to... the "old school" 12" 3-way, would not be one to worry about heating voice coils, over extended power listening sessions (while testing high power / amplifier designs) even on a robust 8" 2-ways. My next sizable speaker investment .will. be a GR-R product. I am thinking H frame dual servo sub(s) would love to do push pull configuration. Saving my dollars... **KEEP UP THE AWESOME WORK DANNY!!
This is top project that delivers without limitations of signal compression that most commercial speakers face....since very few have an efficiency over 90 db ...the recent top JBL monitors aswel ,they lack the 94db /1w ....which makes a huge difference in real dynamics
Wow thanks a lot for the update on the bully. Can't wait to see it finished also the crossover you going to make for you. Can't wait to hear it sound because it would be one speaker I'd be really looking forward to buy. Can't wait to see finish take care and I love those speakers from Gennaro in Puerto Rico✌️
@craigellsworth3952 Diffraction, edge diffraction and baffle step are important issues, that need to be considered for cabinet and speaker baffle design. While some aspects of diffraction are more important than others, it is good to know them and act accordingly, depending on your project. Take a look at the white paper from kef on there Reference or blade speakers lots of time and research went into that design. Pretty cool stuff. Plus a narrow speaker looks awesome in my opinion and disapears Into the room easier.
@@idray986Love a narrow speaker, but a speaker like you describe with this servo woofer would be congested. Because the space behind the woofer will be to shallow. It need some volume behind the woofer. Not not only around it. Bass sounds better that way.
@idray986 Thanx for the news flash. Not that I am unaware of anything you brought up. Have another look at the horizontal measurements. Damn good, don't ya think. For what you described a set of Golden Ear References or PS Audio FR30s would save a lot of effort and possible disappointment.
@@craigellsworth3952 I currently own the Kef reference 5 non metas. I'm Judy just an industrial designer that likes to make stuff too. And you know, also have something the wife likes as well, so a narrow front baffle is desirable in the house. Im sure Danny could pull it off even it a meant a little low end sacrifice
Danny knocked it out of the park with this system. If I didn't already have an amazing speaker I built and needed a speaker, this would be my first choice.
This is beautiful news! I bought some Cerwin Vega RE38's & RE30's back in 98 when i was a teenager. Even though they're not great quality speakers I've always loved them because they're so much fun and i still use them on a 2nd system in our house. In about 2 years we 'll be moving to the Philippines and these would be perfect to bring over there and assemble.
Measurements are taken at 1 meter and each vertical change is done by moving up 4". Since the acoustic centers are so close together and the crossover to the tweeter is so low, the vertical off axis response looks great.
Would love to be able to build the entire speaker. Maybe offer as a R/L/C flat-pack with drivers, x-overs, and terminals? Labor is often a major part of the cost so... just a thought. ;)
This looks like a go for launch 10 9 8 7… I’m excited for this product. Nice departure from the world of 6.5 inch woofers that promise things. Only exception is the Purifi. But in the end? It’s about moving air and rigidity. Can’t wait for the fully built price. I think you are sitting on a winner here.
These would be great for my back-up rock-n-roll system. I have more than enough hardwood to build a pair of these. I would buy the drivers and crossovers. Do you provide a detailed set of plans for this? When do you expect this kit to be available?
It's wonderful to see the cabinet being taken so seriously. On a separate not, I hope you plan on building a version with an AMT, Ribbon or Planar tweeter as an option.
I'm pretty sure that's in the plans. If I remember right he mentioned that in a Brute video that there would be three in this series. The next being the ultimate.
I like the planning behind this speaker. It should be one of the Wonders of the Audio World. I know that it will dominate Klipsch and Polk without breaking a sweat . Keep up the good work and I shall patiently await your final reveal.
PS Audio is having trouble with their floor standing speaker via their inclusion of internal subwoofers. In fact, they had to add a subwoofer in the listening room because they lost the lower octave due to in-room response cancellation. How is the phase relationship down in the lower levels handled in this speaker?
The servo amp has its own phase control so you can dial to your room as needed. The low end can do anything you want it to do. I have a stereo pair of triple 12" servo with my nx otica and the flexibility of bass is hugeeeseee
@@ClassifiedBrief Yeah, but those triple 12" servo-subs are probably set up in the room where they are best suited to room effect and not directly under the main speakers. There is only so much you can do with controls. Setting up a pair of speakers for stereo imaging has its own set of tweaks and adjustments. The ultimate position, for the mains, however, may not be so for low bass.
The use of the phase control that is right on the amp isn't about the room response. It is about dialing in the correct time arrival to the MTM section right above it. The EQ system built into the amp will help with the room response. The level control and extension filters can be used to dial in the room response as well.
What's next? The Beast ! Massive 3 box speaker 1-20hz to 80-100hz 2-80-100hz to 700hz-1000hz 3 -700-1000 hz-to 2500-3000hz 4- and up !.All in different boxes that fit into themselves...
It is great to see a full sized speaker system. What’s the possibility of designing a set as a trapezoid E.G. JBL Ti5000, with the near side towards the listener? This would minimize the box emanating unwanted noise due to the front baffle is reduced in space.
I made it all the way to 2:00 without having a Question for the expert. Why, if you made two boxes for the woofer and mid/high, do you slap them together into one? Is this your definition of "Old School?" Do all of these speakers perform better if seperated? I am a RTTI and MECP educated fan who has enjoyed your customization of commercially available products. Thank you.
That was the old school way. Also, when separating the MTM in it's own cabinet then there is a baffle step loss to compensate for that in this case will knock about 4db of output from them. So this does increase sensitivity, and dynamics.
Hello. Since the bass is servo controlled if I didn't misunderstand, does the speaker have to have a processor that controls this? the speaker uses an active plate amplifier on bass?
this video shows up first and the website lags behind barely anything on there, and we want to see how it looks assembled. this speaker is going to be a great seller and a full range beast of a thing :)
It's the flexibility that works for every application. Great Job!!!
What got me into hifi was watching a midnight session of Jimi Hendrix in a cinema. The panning phased drums in Bold as Love sounded so great, I had to bring that sound home. This new range of speakers are the first I've seen that I think will get closest to that sound. Thanks
You had me at the first knock on that cabinet
Your enthusiasm is contagious! The specs are awesome! Congrats Danny!
love your enthusiasm. those specs were unreal! i LOVE the fact you could run a small tube amp and get a great hybrid sound.
That range is very impressive! Nothing better than a quality 12" in a braced cabinet.
Yes but it looks like a stamped steel basket..thats going to resonant all over the place ..cast baskets are the way to go, cost more but worth every penny.
@@MuscleBN Just did a little photoshop, and it's a cast basket.
@@MuscleBN ...Looks to me to be a cast basket, look again.
It’s a cast basket.
@@MuscleBN It's the same subwoofer they've used for years in their servo sub applications, and it's a cast basket. I have one myself, which I'm actually running in my car.
Can't wait to see the finished version. Great work, Danny!
yes and lets see how he suggest to fix it.
I've been running my Bully(s) build in for a couple of weeks now. Wow!
Looks great Danny! 94db is awesome. There is something to be said about listening to high sensitivity speakers with a low wattage amp.
The best part of high sensitivity speakers is dynamics, the crack of a snare drum, quiet passages that get loud quickly are where high sensitivity speakers shine. Great for rock and roll or orchestral music.
That "thonk" you heard is the ball leaving the park.

Any chance you could put the link up for his svs videos… I couldn’t find them?? Thx
@@noso4609 See it on this page: gr-research.com/product/svs-ultra-tower-speaker-updgrade/
It is covered at the end of this video.
Can never hate a old school speaker setup with some 12’s.
Mine weren’t 12s, but I loved my 25th Anniversary Large Advents(10s).
Props for engineering a big and dominant speaker.
Please send this to Erin for review. Insane measurements. 👏
Made me chuckle--I can tell from the last comment ("on the Bully") that Danny watches Matt Risinger's The Build Show. (Me too.)
I have actually never heard of it.
Interesting design - integrating an MTM "monitor" into a powered sub enclosure - and providing a stand/tower for the speaker - makes a *lot* of sense. You get the bass source integrated into the same footprint, for good phase alignment.
Love it, old school looks. Will be heeeaavy 😂
I was so glad to hear you say that you're going to offer this juicy, juicy speaker as a complete assembled unit. If it is what you say it is you'll have a home run.
I yearn for these.
This feeds my O-S Audio-Wolf.
Run these with my Mitsubishi DA-P20/DA15DC Monoblock.
Oh my!
Bring on the O-S audio!
I bett a tower cab with a pair of these ( top bottom ) with a big old horn in-between would sound awesome.. 😊
Just look how pumped you are Danny. They may not be line source but you seem to be so animated. Looks like these old school speakers have your juices going. Great to see. :) Cheers from OZ.
You had me at "big box speaker"!
Hello?! LOL!!!
If you can, please make a follow up video of a fully built/finished unit. I’m sure a few of us would love to see it
I will.
Looking good! Your enthusiasm is overflowing.
Great to see. and great to see how excited you are with it. Can't wait to see the in room test results / listening session update like u did with the Brute. Congrats on the new Family member
Wow. Those measurements! You’d almost assume that’s purely simulated not actual measurements! …. And that impedance .. could drive those directly from a 80’s Walkman!
Speakers are furniture that play music so WAF is critical .. I’d like to see one properly finished and with grilles.
They look like a lot of fun. More curious how they'd sound for critical listening, imaging, etc.
Well, the Brute was great in that way, so I expect this to be the same, plus higher dynamics.
I'd love to see that 😂
Exceptionally flat response. Let’s see, 10W gets you 104dB. A 20-watt Class A amp would be a marriage made in heaven, and also blow the walls down.
I was thinking the same thing. I have a First Watt F3 15 watt class A that might be the perfect match for these
@@MrBonger88Yeah, pair that with a tube based preamp, as that’s what a lot of First Watt amps have great synergy with, and you’d have a great system using multiple sources if you wanted. 👍🔊😊🎶
It would be 107 db a pair. At 12 ft away that gets you 95 db. Pretty damn loun considering rock concerts are generally 105 db.
I would love to pair these with my Schiit 20-watt Aegir.
That sounds really expencive, rebuilding the walls everytime😂

Man, I would love to hear these! I bet they rock.
Thank you Danny, very excited for these…!
Now I'm seriously drooling.

94,5dB sensitivity🫨😯, wow thats awesome, this speaker will rock 😎🤟
I'm a fan of high sensitivity speakers with minimal xover intervention. Seems like these should fit the bill.
Yeah and you can rely on the sensitivity. No Bs from danny .
I would love that for my theater setup.
Oh man, my jaw just dropped! i want these bad boys.
Great news! I'll stop badgering you about The Bully now!
Now I know what I want for Christmas. !

Looks good. I especially like the high efficiency and self powered, adjustable woofer. 👍
I keep looking for those rave reviews of the Brute on your website, but can't find any.
Awsome Danny , i still love the old school designs. This is a masterpiece in the working
What/who will you be using for your sub amplification?
And how much will the flat pack go for?
The subs are powered by the Rythmik Audio servo amps. We have not solidified pricing on anything yet.
@@dannyrichie9743 any chance you’ll make this an outboard amp and not a plate amp.
Or, can that be an option eventually?
@@cablezilla No, for the feedback system to have the proper control, the amp needs to be no more than a foot or so from the driver.
how many degrees off axis are the yellow and green lines? There has to be a ton of comb filtering going on in the vertical axis.
Measurements are taken at 1 meter and each vertical change is done by moving up 4". Since the acoustic centers are so close together and the crossover to the tweeter is so low, the vertical off axis response looks great.
Never thought I would like Bully’s. Hehe
So happy GR decided to do these big box speakers. I love this style of speaker. The Bully looks really interesting. I bet it rips! 💪🏼🔈👍🏻
Wonderful design!
It reminds me of my Cerwin Vega D7's from back in the 80's when I was in college.
gotta save my pennies for these. these look like the ideal big recording studio monitor.
My thoughts, exactly. Flat, neutral response, wide range, high SPL, and big dynamic range. Perfect for studio monitoring.
Looks good Danny being able to paint it my own colour and the great response it has, I would buy them if the price is right.
Now if I hit the lottery 🤔I am good 👍 looks like a great speaker 🔊 👍
Love it and love it. But wifey and bank account say nope, nada, no way mister…. Hope to see a great video, soon I can dream at. 😘
Hey Hey, Ohh Yeah, Look'n Sweet ! Love your work dude !
Would love to be able to build the entire speaker. Maybe offer as a R/L/C flat-pack with drivers, x-overs, and terminals? Labor is often a major part of the cost so... just a thought. ;)
Well done....That's what I'm talkin about !! .....When can you do a 15" woofer model ??
Your killing it Danny! 👏🏼🇺🇸🎶
This looks like a go for launch 10 9 8 7…
I’m excited for this product. Nice departure from the world of 6.5 inch woofers that promise things. Only exception is the Purifi.
But in the end? It’s about moving air and rigidity. Can’t wait for the fully built price.
I think you are sitting on a winner here.
Sounds like it’s going to be an amazing speaker for most every situation. Looking forward to hearing more about them as it develops!
These would be great for my back-up rock-n-roll system. I have more than enough hardwood to build a pair of these. I would buy the drivers and crossovers. Do you provide a detailed set of plans for this?
When do you expect this kit to be available?
They will be available in a few weeks. Cabinet plans are available. I don't recommend building them out of hardwood.
@@dannyrichie9743 ... I agree, hardwood rings more than MDF.
Looks like my av3 with my 12 servo sub in 1 box . Is there a difference than the sub’s separate? What’s the weight of that speaker 150lbs?
Are these sensitivity tests done with the woofer and mids sharing the same air space and everything playing?
The woofer and mid-bass drivers do not share the same air space. As noted in the video, the measurement was of the MTM section only.
It's wonderful to see the cabinet being taken so seriously. On a separate not, I hope you plan on building a version with an AMT, Ribbon or Planar tweeter as an option.
I'm pretty sure that's in the plans. If I remember right he mentioned that in a Brute video that there would be three in this series. The next being the ultimate.
Can you tell us more about the 12" and servo control? Looks like maybe a Lab 12 driver? Are the electronics your own design?
The woofer is ours. You can read about the servo technology here: www.rythmikaudio.com/technology.html

$3000 with cabinets? Just thinking out loud.
Will the left & right cabinets have mirrored MTM alignment I hope?
Yes they will.
this speaker will demolish most of the 'high end" high price speakers out there for sure
Wow crazy to get such high spl @ 8 ohm can't wait!
These look awesome! Congrats.
That is a very wide front panel for the very tiny tweeter/mid speakers. Why not make it narrower for them?
That would make the design a lot more complex. It would also give up sensitivity.
Reminds of T+A 160 from 90s
It is great to see a full sized speaker system. What’s the possibility of designing a set as a trapezoid E.G. JBL Ti5000, with the near side towards the listener? This would minimize the box emanating unwanted noise due to the front baffle is reduced in space.
Monster sweetspot;
an active, high performance 12", supporting a sensitive, easy to drive MTM top.
Well done!
I made it all the way to 2:00 without having a Question for the expert.
Why, if you made two boxes for the woofer and mid/high, do you slap them together into one?
Is this your definition of "Old School?"
Do all of these speakers perform better if seperated?
I am a RTTI and MECP educated fan who has enjoyed your customization of commercially available products.

Glad to see (and ultimately hear) a fully assembled Bully. Do you have a platform or stand for these babies?
We have stands for the Brute. These will take the same stands. gr-research.com/228749-2/
Exciting stuff!!!
Will it work in Europe 240Volt
Looks good Danny!
Improved version with different driver of Paul Carmody's Pit Vipers!
How to make the good choice between the Bullier ou the Brute ?
They are both good choices, but one is a little more friendly to all applications.
That thing is going to be killer
Hello. Since the bass is servo controlled if I didn't misunderstand, does the speaker have to have a processor that controls this? the speaker uses an active plate amplifier on bass?
The woofer has its own amp that mounts on the back panel.
