Hey All, Check out this link to an interesting tech for bass / subwoofer management I found while searching for my own low tech bass management solutions. So far best placement seems to be 1/4 width of front wall for sub’s left and right. https://www.ecoustics.com/news/trinnov-brings-perfect-home-theater/Looks pretty interesting although expensive. Anyone here use bass management and can tell me where I might start to learn more reasonable cost tech to improve bass response. ? I’ve built a super basic theatre 5.2 in my unfinished basement all from used market, all about 20 year old vintage. So I doubt any current tech will apply. Curious to see if any one has any good ideas. Thanks all. Cheers.

I'm assuming these conditions from a previous post are still applicable? https://www.axiomaudio.com/boards/u...ow-my-speakers-sound-bad-help#Post447434I still recommend the SubZone app in the Apple App Store or Google Play Store for $1. It's very limited in functionality but you get to trial a bunch of listening positions and sub locations to get a gist of what the room is doing at bass frequencies. Things are dialed in today. But I played around with places i used to live in, and none of the ideal sub placement suggestions were decor friendly. Anecdotally, I swore off full range tower loudspeakers because I just couldn't tame the standing waves when placed for best soundstage or decor-friendliness. This was years before my first AVR and the miracle of internal electronic crossover settings, so you might have a different experience.

Yes for the price of new mid-priced car you too can have something you didn’t know you needed till now … Ok … I’ll admit … I want it but not enough to pay for it … My next car, probably a low end Prius, would come in at under 30k usd which I don’t think would cover the cost of a 32 channel Trinnov let alone the subs.
On the bright side other room correction players are also making noises on this front …

Thanks for the reply. Yes those conditions and all still apply for 2 channel. Sounds amazing with straight 2.2 channel with my beefy Hafler amp and pre. I have an old pair of paradigm monitor 9 in that basement space now and m60ti are back upstairs in the big room. Sorry I forgot to mention the change in setup, y’all don’t live in my house, how would you know otherwise!! Ha.
But with the Yamaha AVR now in there with the monitor 9’s it’s not as good while watching movies. It’s not that it sucks at all in fact it’s pretty good but I can tell that it could be better.
I just downloaded the manual for the AVR. Wow. ALOT of menus and settings to go through to get the this unit setup properly. I havent tried anything yet but I think there’s likely a solution with in the AVR itself. There’s various DSP and other settings / filters that may be affecting it all. I will report back when I get time to dig into it. I will checkout the apps you suggested too.

I'm not sure the room compensation programs of mass market AVR's will do much. I leave the Onkyo AccuEQ off; it makes a slightly audible difference, but not one favorably better or worse. But running the calibration program will enable basic bass management such as phase alignment at the microphone position. It doesn't turn off unless you enable direct/pure mode. PSB's Paul Barton discussed room correction in recent podcast (time cued). Bigger rooms don't seem to benefit as much as smaller rooms: https://www.youtube.com/watch?v=TcqTK0rwEPI&t=1079s

Thanks for sharing! Paul is a really good storyteller. Great information. This is why I enjoy this “hobby” there’s always more to learn and improve and enjoy.
Being that my rooms, I think, would be considered large, I agree, not sure how much impact this tech would have. I’m considering adjusting the listening position relative to speaker placement more. I also haven’t tried the traditional subwoofer crawl yet either. I’ll have to give that a go and see where it puts the placement of my sub’s. Is there a 2 subwoofer crawl procedure? I’ll have to find out.

Just for clarity too, I’m looking for improvements on what is already pretty good in my opinion. I think the large space really helps as the low frequencies have to room to be effective and dissipate naturally. When I added the second subwoofer things improved, smoother and more whole room encompassing, I’m hoping for more impact and subtlety. I think adding the second d sub made me rethink placement too which was an improvement.

The current consumer version is SOTA and surpasses the antiquated 6-Axis, Logic 7, and Pro Logic Iix. I can never go back to stereo listening. DTS:X adds some unwanted equalization in my setup, but that could also be something to try.
