I sure like Troy's work. That Nighthawk speaker looks fantastic. I hope he gets it worked out. I wish him all best and great success with his business.
Was in the pro world for 30 years. I haven't heard one thing you said that isn't true. I love that you are using an organic horn flare. I may be calling you.
I recently ordered a plan for a customized version of one of Troy's speakers. If people are interested, I will post something about the finished product. Assuming I manage to build it, that is!
That would be excellent! If you do, post it on the Forum as well. Whether it's a video or pictures, I know people would be very interested in seeing it. www.toidsdiyaudio.com/community
Wonderful engineering and craftsmanship. Thanks for bringing this to us! The topic reminds me of the 90s car audio trend of horn loaded compression drivers carrying the front stage from 800Hz and up. I ran a full USD Audio system in sound quality competitions back in the day, and had pretty good luck, after a lot of tuning, both physical (foam blocking), EQ, and time alignment. I've always wondered why that tech has completely disappeared from the car audio market. I assume it was just too impractical (installation and tuning) to capture enough of a market to justify it. But, when you get it right, it's really something to behold.
Good stuff! A follow up question would be re the differences between a waveguide, a "true" horn and a compression horn. It appears to me that Troy's horns lack the compression chamber and phase plug that characterize most horns. Without being privy to the nuances, I'd think they are waveguides. BTW Dr. Earl Geddes would be another great guest in the same vein. Thanks!
Jeez, what is with this name calling - regadless of the name they all do the same thing - provide acoustic loading to the driver and directivity and impedance matching to the other side.
@@VEC7ORlt They are not merely different names for the same thing, despite similarities of basic function. Understanding the differences leads to a better likelihood of meeting design goals for those of us who actually design speaker systems. Not sure why you find this offensive.😕
@@VEC7ORlt a "compression horn" sounds like a made up category. Like an unnecessary definitional branching. Any time the diaphragm is bigger than the throat there is necessarily a degree of compression ratio there, and that describes almost all horns (including Most of Troy's), and a front chamber is a function of scaling of that difference. More importantly @naturalverities is simply wrong about his statement as the Crowe designs run the complete gamut from undersized drivers as in his Rullit 80hz design, to even running phase plugs on bass horns such as his large ES horn. Phase plugs have specific uses, and front chambers have specific uses, and all of these things are balanced across bandwidth demands and driver behaviours. I don't think there's a useful definition that categorically divides "waveguide" from "true horn" without creating loads of messy carve-outs to accommodate certain designs which are commonly thought to be one or the other.
@@weatheranddarkness you know what, forget I've asked - I know enough about horns to not even participate in this nonsense. I'll stick to my acoustic loading, impedances, directivity indices and leave the name calling to the marketing and audiophiles.
Bucket list for me is to get Troy to make me one of his exponential horns in solid walnut. I am currently using solid walnut open baffle speakers and they are good, but nothing compared to what I imagine from Troy's horns. Combined with my diy triode electronics which are also walnut based, I think it would be a perfect blend of art and sound.
Great interview. Would love to hear if there are some rules of thumb w/r/t lateral, vertical, and depth dimensions for tweeter horns, such that they roughly match a woofer of a certain size.
Ha thats fun to see Joseph (Troy) in one of your video's :) its such a small world. i remember talking to both of you at different times :) Looooooveeee the looks of these horns. they evolved to some masterpieces by now ! i remember we talked planar speakers and B&G back in the day. maybe we still can make something custom that fits horn loading better someday. still have a question about using a line source 1 meter tall in a horn, so i might drop you a question about it later on if thats ok. (if you even got time for such things) anyhow Toid and Troy nice video !
As a happy customer I can vouch his plans are produced with exquisite detail and I feel are exceptional value. Especially when if an improved version should become available you will be given access to that version also! Take a look, you’ll be impressed.

I'm wanting to build some diy horn speakers right now with a horn I can buy off the shelf ... holy crap this was informative! I thought I wanted controlled or constant directivity for dispersion reasons but my main goal is sound quality so I guess I'm looking for exponential or bi-radial or something. I have some 15" jbl 2225h drivers I want to use, which I want to cross over between 500 and 800hz, and if possible I'd like to avoid a 3 way design. The speakers they're currently in have 11x4" exponential horns with akai hm-80 CDs, but the crossover point is closer to 2k and so the JBL's aren't great in that upper region in terms of dispersion or detail and clarity compared to a small horn loaded driver. I'm in forums seeking advice but most of these people are older guys into expensive vintage hifi stuff and they think 50 year old horns are as good as it gets .. I beg to differ. But there are so many options it's hard to decide. Any thoughts on a good off the shelf CD/horn pair available for close to 500 bucks, certainly under a grand, that can cross at 800hz or less? Or would I be better off crossing at 1200 to get better HF performance, mated to the 2225 which might be fine to 1200, though not super ideal. Or I could go 3-way and have a smaller pro 10" to cover say 100 or 150hz to 1.2khz.
Very difficult to hear your guest and you were screaming at me. Not sure if you are doing what radio shows also do this the same way.....its not comfortable, especially with ear pods and having to turn it up to hear your guest and then be fast and turn you down because it was hurting my ears. Great topic and thanks for the channel.
Hes a legend in the making. Pay attention people...
I wish this was 2 hours! Troy seems to be a really good guy. Great interview too 👌
He is a really great guy. If you enjoyed this, you should check out his TH-cam channel and subscribe.
Yeah! Great professionals, awesome.
I sure like Troy's work. That Nighthawk speaker looks fantastic. I hope he gets it worked out. I wish him all best and great success with his business.
The day I encountered Troy's content on TH-cam, was a good day.
I've followed closely since.
His Kung-fu is good...

Beautiful … as someone who owns Boenicke W8se+ speakers .. i am in love with the woodwork ..
Really beautiful work and well thought out. Inspiring!
Crowe Such a humble guy.
Very interesting. Beautiful work!
Beautiful artwork .. Love to see these pop up in my news feed and videos. Thanks for bringing this to a wide audience =)
Great video, and very insightful interview.

@@Toid I'd be happy to. It's a humongous speaker and I'm a little intimidated. Go big or go home, right (he says nervously)?
Very, very nice presentation. Greetings from Portugal.
I really liked this.
That's awesome. I want a buy a diy kit with custom horn like that. My wife might actually let me show speakers
They are beautiful ,aren't they?
Awesome interview, what a nice guy and so open with his knowledge.
Horn model 1200 by J. Crowe - very good! (incredible dispersion and plot)
Thanks. They look awesome.
Beautiful work !
Great interview. Smart man

Awesome stuff! Does he offer DIY horn kits or templates?
That's a very good question. Maybe I should have asked it
I think there are some $15 plans on his website.
@@philiptalbert458 plans are easy, the logarithmic curve needed for the horn is the hard part.

Wow great video. Love the cnc And diy speakers. Where have I heard that before🧐🤣
Wow! What an inspiration!
I often wonder if a golden spiral horn would be the ultimate in horn geometry?(using the holden ratio of 1:1.68
