The active stuff works. Think of it as a unit that plays back the inverse of the room's bass modes. Bag End makes one too. They make good stuff. The approaches these companies take wll be slightly different from each other.

PSI rubs me the wrong way with Bob Katz shilling for them and also lacking documentation. Too much Swiss wankery. Bag End I like because they are pro audio and the have publicly available documentation that explains what they are doing and how to configure it. Less mysteries. Less audiophile bullshit.

That’s what annoyed me about this PSI unit. I couldn’t find any descriptions about how it actually worked. Made me sus.

Bag End - there’s a name I recognize from the electric bass world. Didn’t realize they had ventured out of just bass gear.

still quite expensive

Yeah, will probably keep an eye out for Bag Ends on the used market.

Can I point one at one of my neighbor's car? Can't wait for it to get too cold for him to sit around blasting...

It will work against your neighbor. Just record and get a spectrum analysis. Most likely, it will be one-note. The Bag-End can kill up to two distinct bass frequencies. You can set the width of the band.

@purr1n Started looking into it after a quick n dirty sweep with REW showed me why the low-end in my room was annoying me at times. https://i.imgur.com/qg1ujUS.png

If it mostly happens with digital some eq with something like roon could take out a bit of the sting of those peaks. Those electronic basstraps are probably better for the ringing though.

Yeah, it's the decay I wanna try to control.

Maybe the Geddes approach to multi sub is an idea? You don’t strike me as someone wanting to mess with hpf on the mains and dsp on the subs.

More subs would help, yeah. I've done some EQ on the sub I have within the SVS app.

I'm just wondering what kind of solutions for taming low-end decay there are that don't significantly take over more of this living room that I share with my partner.

Honestly i think you should be happy with what you got, or spend big bucks on the e-traps. More subs will smooth decay but not reduce it much. Room treatments for your problem area are probably not feasible even if you were alone.

Maybe a ripole sub? They are more directional and trigger less room modes.

Yeah, Bag End might be the ticket! And yeah, passive treatments for those frequencies would be kind of nuts for a living space.

Would more subs help? I don't know. Maybe if positioned right?

I've never done this stuff, but I remember reading that you can't cure a bass node with amplification, because it would take an infinite amount.

You seem to have to modes at around thirty and fifty Hz, if I understand it correctly the bag ends will be able to deal with these, if you want to get reverberation time done in the whole bass region the PSI will be better. I know some who found it worth the money. At that price a dealer should be willing to loan the PSI to you. Then you can decide whether you think it is money well spent

If you just want to speed up decay times to reduce muddy/boomy bass and not manipulate FR, passive traps work well. Whether they blend into your decor is a separate question.
