How does adding a second subwoofer improve your systems SQ?

And is it the same as the first one?

That would be the way to go, you wouldn’t have different left and right main speakers.

And don’t run them of the "sub output" if using a HT amp, set the programing to "no sub" and set your left and right mains to large and get the signal for your subs from left and right main pre-outputs

Or if using a normal stereo pre amp use these on it’s L & R outputs to supply both your poweramp and your subs

Since bass trap advocate Erik Squires is playing the "cultist" card to discredit multi-sub advocates

@audiokinesis

I’m not discrediting multi subs. I’m discrediting the cultish behavior on the proponents on Audiogon. As I’ve written, it is characterized by:

1 - Refusal to accept other solutions are possible or more applicable to specific questions by posters.

2 - Insistence on the swarm being a solution to everything a poster asks about, regardless of application. "Help I have noise on my left channel." 30 seconds later ... "You need a swarm!"

3 - Lying about what other prominent professionals have stated.

I have no particular interest in whether some one finds the swarm a useful solution in their environment. It’s the cult-like behaviors above I find distasteful, and that you seem to be happy to misstate my position despite how clear it is. I also don’t care if you promote it as a possible solution to the general problem of finding good bass in a system.

I do care people I interact with do so in a respectful and sincere manner, and this has definitely not been consistently the case around this issue and as a result I have grown a profound distaste for those who promote it. I don’t think that’s unfair.  Your sentence, quoted above, reaffirms my choices.

What's that?  Cake and eat it too?  

I use a "swarm".  I guess that's what it is, I have 4 subwoofers.  I encourage people to give it a try.  Is that "promoting" it?  I guess it is.  Why would you have "profound distaste" for me doing that?

I don't have bass traps (I do have some acoustic panels however).  I also don't tell people that my way is the "only" or "best" way nor would I or have I told someone that using bass traps can't be effective. 

My friend has the best system for bass I've heard, hands down.  Two subs.  Bass traps. Diffusers.  No swarm.  It's awesome!  To me.  Someone else might think it's too much bass.  Or not integrated enough. Or whatever.  He loves it.  I think it sounds amazing.  Someone else might have a different impression.

One of the great things about this hobby is that for many aspects of it there are a multitude of ways to achieve the outcome that is "best" for the individual hobbyist. 

"Best" being subjective because everyone has different tastes, spaces, and budgets to name a few common variables.

@erik_squires

So it sounds like you’d rather have an internet squabble based on exaggerations, accusations, and maybe even "distaste".

I don’t blame you. That clip I posted kinda makes you want to steer the conversation away from the relative technical merits of bass trapping vs multiple subs, doesn’t it?

In case anyone missed it, just watch for thirty-one seconds, from 37:37 to 38:08 (it’s cued up):

For the record, I agree with Erik that bass traps are beneficial. I don’t think I have ever said otherwise.

Gee @audiokinesis

I'm not having a squabble at all.  You said I played a card to discredit a technology and I corrected you. Now you are again taking a curious angle to my very clear and direct statements.  

As I have said, I don't care if people chose a swarm or not.  I do care how people behave in my environment. Calling out poor social behavior for what it is is not playing a card or discrediting a technology.

I suggest in the future if you'd like to carry on undisturbed that you avoid using my name in vain and I'm sure I'd be leaving you alone.

Best,

E
