Thank you for the best content on TH-cam covering home theater. Cant wait for the Audyssey app guide!
i just built a pair of mini martys for a pair of 18 inch subs..sounds great with movies. but need more bass with music this video will be a big help to set my dsp ..
dig the new setup, looking really professional!
Great video
Ugh, I'm so sorry man, I'm always super late to these! I don't check my Budget Audiophile YT channel very often, I need to do that more! I would love to see, if you had time, a video talking about sealed subs. Not necessarily a "comparison" but just talking about sealed subs and why the ULF freaks like me often prefer sealed subs/Infinite Baffle as opposed to super low-tune (like an LLT) vented subs.
RE: This Video . . .I do run a lower HPF. Previously I was running NO HPF but I found that it would ruin my response in the sweeps so I run a super low HPF and that cleaned everything right up. I find that digging into the triple digits at, say, 11Hz, is a lot more fun in my theater than hitting 139dB at 30Hz. But that's just me, I'm a deep-note junkie!
I can't wait to see that audyssey video of yours, I was messing around in it but couldn't really figure it out, so that will be EXCEPTIONALLY helpful. Right now I'm running with MultEQ32 turned off because, like you mentioned, it obliterated my response. Worked super hard to get a nice response just for Audyssey to ruin it. Currently I'm only using Audyssey to tune my mains.
The new house looks like its in a rather nice spot!
Perfect timing. Thank you!
Great video thanks my friend 😊
Highly looking forward to that audyssey editor app video
Nice👍 I remember u covered little bit about this in Ep#7. Expecting more videos from your channel.
Welcome back
Thanks bro!
Can you do a video on how to use REW to set the eq that’s built into a home receiver?
Thanks for the informative video! Would that apply similarly for sealed subs or the slope can be less aggressive? I'm just not sure how to finds the numbers or measure it vs. a set port tuning frequency.
Very important video that no one talks thank you
A question if I have plate amp it doesn’t have a subsonic filter so I will have to buy a miniDSP correct
The avr why don’t they have this feature built in so that we don’t need to buy a miniDSP or a plate amp just buy a superb poweramp and drive a passive sub
Wish my iNuke had an option for a highpass under 20Hz. Sure I can use shelf filters to compensate but it'd be nice to simply set it lower. 🙃
Hello make long story short love your videos you made get the miniDSP I play with some next I Order some 18” subs doing the diy I order from parts express the tech recommended me to xti 4002 crown amp he also recommended me to the clean box pro ok watching this video my question do I need this Art clean box pro for the noise of the amp or can I just use miniDSP I’m planning to run 4 18”. Two in each GSG seal cabinet
Will you also make vids about EQ'ing mains? Instead of calibrated with auddysey?
Just did this last night. my cheap sub 12HGs drop off a cliff at 24hz. So I got my highpass BW 48 at 22 to where it started to affect my measurement.
great video..
Thanks John!
Can a sub's tuning frequency be inferred from a frequency response graph if the tuning frequency specification is not listed?
I used REW as per your video and aligned my 4 subs. Thanks a lot for your videos. After I pushed my calibration to miniDSP. I do measurements to confirm if the new calibration has been ported. It works. But then when I set Crossover settings as per this video and rerun the measurements, it changes the whole sub response curve and introduces new dips and gains across the whole response. When I revert the crossover settings, it reverts back to the calibrated response. Am I missing anything?

Hello, I also faced the same issue.
After applying the minidsp nice house curve to the subwoofer group, when I apply crossover on AV Receiver, it breaks the house curve.
The solution for this AV Receiver Crossover settings issue is explained in this video from Home Theatre Gamer (Part 4 of his 6 MiniDSP HD series videos).
Basically, the issue is missing time alignment between your main FL FR speakers and your Virtual Subwoofer group:
For example
- for crossover 80hz it requires different delay X between your main speakers and your virtual subwoofer
- for crossover 100hz it requires different delay Y between your main speakers and your virtual subwoofer
- for crossover 120hz it requires different delay Z between your main speakers and your virtual subwoofer.
- and so on, and so on
Its not like the same delay/time alignment between the main speakers and the subwoofer group, will work for any Receiver crossover setting, no.
Could this method be used setting the HP filter on GSG Devastors?
Instead of using this Minidsp, is there any cheap alternatives?
I have a Yamaha avantage 1080 receiver. The sub out of the avr I hav connected to the poweramp that has no dsp. The power amp is connected to my passive sub. Can I use Yamahas internal dsp to do subsonic to save the subwoofer or I need to buy a miniDSP.
If yes what are the main functions that miniDSP has that a Yamaha avr dsp doesn’t have purely subwoofer point of view
Any chance of going over mini dsp tuning vs arc2 room correction tuning as it has changed so much to allow you to do more things.
im thinking of buying the mini dsp 2x4 how well does the regular 2x4 dsp work on a pair of mini marty subs,,?
Please give a connection diagram..
From avr sub pre out to the diy sub
Really confused with the connections
I've been following your videos and they have been really helpful specially for a noob like me. I do have some questions and would really appreciate your help. I'm trying to integrate my new sub ( SVS PB-1000 ) to my 2 existing old subs ( Paradigm PDR12 and PDR10 ) in my dedicated HT room that's 19X13X8. I know they are mismatched subs but I wanna see if I could possibly make them work together.
1) Setting a HPF with the MiniDSP specially with 3 mismatched subs that have 3 different tuning frequencies will it work? Does that mean that I will set 3 different HPF values on the MiniDSP?
2) Being a noob I have no idea what the tuning frequencies are on the SVS PB-1000/PDR12 and PDR10.
Thanks John!
You're subs are brand name subs so the HPF is baked in already. If they were DIY subs you'd have to do it yourself.
@@hometheatergurus Thanks so much for the quick reply. Sorry for the noob question. So I don't need to set any HPF filters?
Great channel!!
Have you thought of doing the firmware/software upgrade to the 2x4HD to the DDRC-24 so you can get Dirac Live implementation?
Thanks! No I'm not a big fan of above modal region auto eq when the room is setup right and you have good speakers. I'll be shooting my preferred setup methods in a few days where the reasoning being that approach will be explained.
Great channel but hate the intro noise
Thanks! Yeah it's getting old for me too. Im currently playing with a new intro.
Would it be possible to make a video on how to set up the miniDSP for something like Crowson Actuators?
Sure. I actually have a MiniDSP Flex coming in for review so I'll be using that. I will have tactile transducers in the near future so I'll absolutely cover dialing them in.
@@hometheatergurus Awesome I'm looking forward to it! There's not much info on how to set these up so that will be great for the community!
I was under the impression you wanted to do this before ever running my sub (full marty) but in episode i believe 7 you set it toward the end after running sweeps,aligning etc. Does it matter if set before or after sweeps?
You can do it either but the important thing is to make sure you don't set it then boost it under the filter during eq which negates the filter.
I don’t have a laptop to do this so I’m going to get one at the pawn shop. What software do I need to make sure it has to program my mini dsp hd
You'll need to go to the minidsp website and download the HD 2x4 plug in. If you watch the beginning of ep 7 I walk you through the process.
What’s your email address. I ordered a laptop a umik and a mini dsp hd. Do I need the 2x4 hd circuit board kit also
@@shawnulery51 no you'll just need what you have now. At the beginning of Ep7 I cover it all more in depth as well as how to get connected etc.
Will you also be covering when to apply the Low pass filter?
We don't set that in the subs amp. The avr or processor sets those which was covered in a few videos. The latest is the audyssey video. Also ep 9 covered it.
@@hometheatergurus thanks. If you are referring to the 80hz crossover at the avr yes that is set in the avr. I was just wondering if there was anything additional.
@@diybuildandlife207 you also have a LFE Lpf.
@@hometheatergurus thank you
You're welcome. Ohh and we did use a lpf to filter noise in the sub hum video. Forgot about that one.
What would you set your cut off frequency in the case of using port plugs? My PC4000 is 17Hz standard, but with a port plugged is 15Hz. Do I still want to use 17Hz for the cutoff even if I have the port plugged?
No, you can change the HPF if you plug the port
Is there somewhere that will CNC MDF and send it to you?
You mean for the hammer sub?
@@hometheatergurus I mean for a sub or any project. I can draw boxes in CAD all day. Wanna maximize space in my Honda trunk. I’m just not up to cutting wood in the driveway like I did in high school.
