When you going to add the 3rd one?

Ha ha, If I had multiple rows I'd consider it. Its a long rectangular room and the back half has a pool table and small bar so the HT seating is 1/3 of the way into the room and every seat has great sound with the two subs in the front stage. I'm going to invest in a couple extra absorption panels to tame first reflections on one of the sidewalls but that is it!

I'm planning on going 7.2 with all subwoofers.

@GTABeancounter I'm guessing Gik Acoustics or another similar brand of absorption panels?

No knock on GIK, but I know they are more expensive than what I'm willing to spend. I have previously purchased a couple panels from acousticpanels.com for my ceiling (its a basement HTR beneath a sunken main floor room so the height is only 7' and the reflections were quite bad). Those panels did the trick for that issue.

FWIW, I have no bass traps so I'm relying on EQ to fix the bass. I recently upgraded to an Anthem AVR and have played around with ARC and learned a few things about my room in the process including that by moving the couch forward about 12" a serious 150hz null was virtually gone (there really is something to the 1/3 rule!!!)

You still using the Anti-Mode as well?

The antimode is in the chain for now. I did a great deal of research and found that antimode works in the "time domain" unlike arc. Anthem itself recommends using their PBK correction in addition to ARC if multiple subs are in use.

The DSPeaker folks say the antimode is an easy way to address phase between two subs and this may be why Anthem recommends PBK even with ARC. I'll live with it for a couple weeks before seeing what happens if I run arc without it.

I’ve actually been listening looking at the pb-1000 and sb-1000 this last week. Glad to see the PB-1000 gets the nod here at sbaf.

I think a lot of folks here might suggest you go sealed. Especially if you are most concerned about music AND your room is small enough to give a sealed sub enough boost via room gain. Having said that I have no issue with how my sub handles music. But that could have something to do with Arc and/or the anti mode.

Hmm, this makes me wonder if having a <Sealed-design> (also) in our L/C/R front-speakers, themselves, (for a HT setup), would also make any logical sense? You know what I mean?
Like for a better / tighter fit (closer to walls) w/ more positioning choices & therefore, simpler room integration & also having less need for Acoustical Panels or maybe ONLY for First/Ceiling Reflections, w/ a thick/absorbent Rug. Thoughts?

Flat Acoustic panels, rugs, furnishings will do nothing for bass frequencies. There is also really no issue with placing a front ported SUB in a corner if you are employing eq. SUB eq will do an adequate job with pulling down peaks but there is nothing you can do about nulls.

DSPEAKER actually recommends corner loading a single SUB to minimize nulls and allow the eq to pull down peaks. If your room is 2000 cubic feet or less a pair of sb1000 in the front stage would be great. Especially with decent eq. (Arc, xt32, direct, antimode, mini dsp etc.)
