Probably not that quick. I'm working on the first draft of something else now, and I'll be traveling for a week in June, so my time will be a bit limited. I do have it hooked and running though, so I have started jotting down some notes at least.

If you take yourself too seriously, expect me to do the exact opposite

I'll post some pics this weekend. Hopefully my wife lets me move them around.

We are moving in next 60days. My back has been hurting a lot!! So I might just leave them in the boxes. 600lbs of subs.

What kind of spl do 6 FV15HP's produce at 20Hz and 10Hz?

What is your in room -3dB point with 1 port 14Hz high damping rumble filter off?

Curious...

Looking forward to the review. Especially because I don't recall you reviewing a large ported Rythmik unless I missed something.

Are you a reviewer of subs/speakers? Or is the FV18 for personal use? Just wondering based on your posts about the FV18.

Don't have all 6 together yet but I'll let you know. Even know I'll never run them at 14/high with rumble filter off.

Will have to watch more content but I can already tell it's much improved.
Glad to hear it is improved. This is with or without the minidsp? Setting the sub to 60hz will loose some of the good LFE content above it, I am not sure I want to do that myself.

He Reviewed the Salk/Rythmik sub, which is very close in performance to the FV15HP:

http://www.hometheatershack.com/foru...er-review.html

He also reviewed the L12R, which could be a big ported sub (depending on what you think "Big" is):

http://www.hometheatershack.com/foru...er-review.html

He also reviewed the sealed F8 and E15hp:

http://www.hometheatershack.com/foru...f8-review.html

Rythmik E15 vs SVS SB13 Ultra

That's all that I know of in terms of Rythmik. I follow his reviews closely, since I am planning a dedicated theater room very close to the size of his room and he goes through things thouroughly with both music and movies: output, impact, detail, etc. I'm looking forward to reading his thoughts on the new FV18.

Thank you for the kind words, and the links to my Rythmik articles! You hit them all - that's the full catalog.

I missed that first one; have read the rest, especially the LV12R one, since I got that largely because of the review and how it outperformed the SVS PB-1000/SB-1000 reviews by him.

Yeah, the LV12R is pretty big, more than twice the L12/F12 but the 15 and 18 ported models are truly huge and 2-3x the weight.

This is with the miniDSP and boost still.

What frequencies are you boosting to the subs? I do some boosting for TTs but always use cut-only for sub PEQ filters. Cut-only generally increases subwoofer headroom while boosts eat into it.

I'm just adding 12db of gain to the outputs on the miniDSP 2x4 HD because I was only getting .5V out of the outputs at reference MV. So not boosting through PEQ, just Output gain. Seemed like the 1.5V coming into the miniDSP 2x4 HD was being split by the 3 outputs being used.

I am using PEQ to input 1 which routes to outputs 1 and 2 that go to the FV15HPs. There is no boost in the PEQ filtering now.

Although I thought I got it dialed in well yesterday, I was disheartened today when I threw some other demo scenes up only to go back to hearing the very boomy sound. I've also have a weird freak summer cold for about a week so I wonder if it could just be some stuffiness causing it. I probably sound like a crazy person flip flopping in opinion daily but there really are times where I'm listening and have a big smile on my face and other times where my ears are literally hurting. Been trying to figure out what to do all day. I'm considering returning the second FV15HP and taking the hit on the shipping, then getting an upgraded AVR. I'm really not sure if the second sub is helping at this point and if anything, think it might be hurting my SQ because of my room and limited placement options.

If you want a avr I'm selling my denon 4200. I'd give you a very fair deal.

With them stacked it should not be hurting. Make sure they are getting identical signals and are setup identically. Measure with REW and generate waterfall to check decay. did you try 14/Mid yet. Low damping is boomier.

Yeah actually today I've been running 2 port, 14/mid. Actually busting out REW now. Will post those graphs soon.

Thanks @Timothy1180 but I need a 9.2 channel AVR. Have any of those lying around?

Go to your local Audio store, buy a x4300 Denon, leave your minidsp out and run Audyssey calibration on your subs using both sub outs of the X4300. Let subeqHT does its thing, bump your trims up and see if you are happy. If not, return it free of charge. I really think the boominess you have been experiencing is from your minidsp. Have you even tried what I suggested? Leave the minidsp out that is?

Denon 4200 processes 9.2. Only has 7 internal though. Be great time to get power amp. I'm going to get a onkyo rz1100 for a great deal. Might be replacing Yamaha 3060 in my bedroom. Interested in Yamaha?

Here are ones I just ran with 1 port mode, 14/mid.
