Need help placing a second subwoofer.


Need help placing a second subwoofer.

If indeed two is better than one, can I get some opinions of placement for both?

Anyone try putting the second one behind the listening position?

All feedback appreciated.

Dali Euphonia MS5 speakers. M&K dual 12” sub. The second sub is some semi lame 10”, but hell I only paid $5 for it at an estate sale. (Velodyne CHT-10)

Here’s a link showing a photo of my set-up:

Excellent, thanks! I think I'll start experimenting...
But by what I'm hearing, the main sub shouldn't be front and center like mine is, but closer to the main speakers and probably lightly forward because of time delays of the lowest frequencies, is this correct?
just put them where they look best.  you wont notice a difference anyway.  
+1   millercarbon's statements.

And I'd run those Dali's full range unless you feel the need to high-pass for whatever. Unless your amp is small I think the midrange will do fine with the woofers tagging along and not high-passed. Plus they go low, and I'll bet very well on their own.

Set your two subs in good locations to maximize the number of room nodes, not the volume of only one or two, if you want the smoothest bass. Two corners are a bit suspect, especially if you cannot equalize them.

Your bass should not get louder. You should just hear more of the lower bass and it will sound louder because of that. Plus most well-positioned subs add a sense of air and recording venue.

Have fun and good luck. Add two more subs when you can...  :-)

Correct in the sense that is what you are hearing from people, but incorrect in the sense it is wrong.  

Subs put out low bass. Low bass is very long wavelength. So low we don't even hear it until one cycle. So long by the time we hear it the wave has traveled across the room. At low enough frequency it has time to travel back and forth being reflected and canceling itself before we even hear it. 

Time delays in other words are irrelevant.

According to this from a very reputable source with years of industry experience and thousands of customers there is a best setup for 1, 2, 3 or 4 subs that includes front and center if just one.
