The only real downfall is the potential extra time needed to get them to constructively align.....
Its taken me a bit to get to where I feel they are complimenting each other and work well in my room....
But the extra time spent and the result are WELL WORTH IT, so dont get me wrong...
I'm a HUGE PROPONENT of AS MANY SUBS as you can get into your room as extra overhead is ALWAYS a good thing, it means you need less power, have less THD....

In my case, the front sub does the CC's heavy lifting & LFE duties only. To set the Surrounds to Large I must set the LR* to Large.
*Good to the low 30s
I pray the 976 allows independent setting of Large or Small as I choose. Of course if I happen across another B1.39 or two more Evidence subs, well...
I'll cross that bridge when I get there. Tony

Two subs were definitely better than one. Three were certainly better than two. Now let’s see how number four pans out.

These days each “corner” has its own sub - by EXO for their respective channel.

Crazy? Maybe but movies & music are a real kick.

You guys must have some serious theater rooms. I can't imagine using another sub. I'm afraid the windows are going to blow out as it is. -

@Airplay355 It's not about getting more bass necessarily. Multiple subs will work to break up the standing wave issue that ALL rooms have and therefore give you BETTER bass. That plus the fact that more means that each one doesn't have to work as hard.
So it isn't just about maximum output (although for some bass heads it might be) It's about smoother frequency response and better quality bass that isn't being mucked up by the room. -

Hey @gp4jesus
Since my CS1000p center has built in subs with power ports, does technically mean I have five also? -
Okay all four subs (*well five if you wamt to include the subs in the CS1000p center speaker*) are set up and running. Four is DEFINITELY BETTER than two! I'm not hearing as many issues with the usual room induced peaks and valleys (caused by standing waves) AND there seems to be a bit more impact on transients that I didn't expect to hear-like sudden sounds that come out of nowhere that they love to mix into movie soundtracks in order to startle you. Something falling to the floor for example.

Watching the reboot of The Mummy with Tom Cruise.
Bass is amazing!
Excellent transient impact and no boom whatsoever when the THX processing with the Audyssey EQ is turned on. Dolby True HD is sounding gooooood

Having a CC F3 of 35hz is great. RTi A7 & 9s “subs” dig into the low 30s too. But most would agree “they ain’t the real deal (true subs).”
Most would agree, “...at minimum well into the 20s.” Some would argue “you’re not serious unless” you’re in the the high teens at 90+ dB, under 10% distortion.

Using that stringent criteria then most subs that are being sold out there in the marketplace would not qualify as true subs then.
Oh well I’m just having fun with this (*after all fun IS what this is supposed to be all about riiiiiiiiight??*)
Was watching Justice League on HBO yesterday with one of my former audio store bosses and there was this bass note that was really deep which partially pressurized the room. All of a sudden I can’t recall what scene it was in. I bought the 4K Blu-ray combo pack week before last and now I can’t wait to pop it in the Oppo! -

@rpf65 Neither do I. I'm just happy!
I guess that makes me a bad man???

If you’re so happy about audio that you confuse yourself, you’re in the right place.
That sounds like something between a motto and a maxim. -

Horror flick...monsters that hunt by sound.
Steve, the ambient noises make it a good atmospheric movie. Lots of other animals and noises to hear and when the monsters are moving around in the woods or a corn field, it produces a lot of surround effect."Some people find it easier to be conceited rather than correct."

Was the first full movie we watched after getting my beast, scared the crap out of the whole family, not for the content (which was bad by any means) but by the sound mixing. It was fantastic. -
Watched James Bond Die another Day first on cable. Then halfway through decided to pull out the DVD and listen to the 6.1 channel DTS-ES mix. I DO NOT remember it sounding like this!!

Sounds like you're enjoying the H e l l out of your system there @honestaquarianSo, are you willing to put forth a little effort or are you happy sitting in your skeptical poo pile?

Oh yeah the CONS part!
Uuuuuuuuuhhhhhh four subs take up more space than one or two??? -
The only con I can think of for multiple suds is more things to dust.
-
Hmm, cons... well, when I had dual subs there was way too much bass for my small room, which ended up making it kind of muddy and undefined. But I have a small room, so my experience probably doesn’t apply.
You guys probably have subs costing 10x my entire system as well, so it applies even less

@mlistens03
TURN YOUR SUBS DOWN!!!
I have stereo subs in my bedroom (2 PSW-200’s in the plexiglass enclosures) and that is what taught me that valuable lesson. Once I turned the volume on the subs way down, they stopped overloading the room and exciting all of the room modes so much and everything sounded MUCH BETTER. My bedroom is very small, hence the overload issue. That taught me to do the same when I started getting more subs in the living room theater system (*well that and the Audyssey set up has you setting them for 75 Decibel volume level which is pretty low*) -

They didn’t go low enough! By the time I got them to almost perfect, they would cut out completely. I guess that’s my fault for having too big of subs, when I switched back to one, it was better.
So just saying, if you have giant subs and a pretty small room, then it may not work well. Otherwise, two subs are better in every way (except space saving) but in my 12x13 or so room, two super powerful tens were just too much. -
4 PSW-150’s in the living room and 2 PSW-200’s in the bedroom. Multiple smaller subs almost always work better than larger ones (exceptions to every rule obviously) These are not expensive subs and I got them on eBay used every one.

I know that, but at the time I was planning on getting mains that would cover the bass frequencies better. Now I’m heading towards the idea of a small set of speakers and two small 6 inch subs or something (like the Polk MicroPro subs, those are 8 inch subs, yes?)
