Is More Better?


I currently have two SVS SB 3000 subs in a system and decided to add two more.

Will the good people who have been there, done that share suggestions to make

the addition of the two subs a little easier for me?  Thanks in advance.

@janewyman 

what are your approximate levels on your current subs?  

the reason i ask is that if they are on the low side of the range, adding two more subs could over power your room. 

I assume that for music you do not want to increase the relative volume compared to the rest of the music, in which case you will want to decrease the level of the original subwoofers.  

adding two more subs will give most of the room subwoofer impact at higher frequencies and more rumble headroom, not just the sweet spot or near wall boundaries.

SVS allows returns, no questions asked, within 60 days.  If I cannot get the new 

subs to synchronize and complement the existing setup, I will simply return

them. It does seem more complicated than I anticipated, but it will give me

a challenge and something to do on these hot summer days ahead..

My recollection is that most believe there is a very noticeable improvement going from 2 to 3 subs and a bit more going to four, but after that pretty much diminishing returns.
 

Todd Welti is The Man when it comes to multi-subwoofer system set-up and his Harman Kardon article is well worth reading. While there is a  bit of science to it, you can also do pretty well by randomly placing a sub along each wall. I strongly recommend using REW to help guide your replacement. Sometimes the flattest frequency response worsens  room modes, which I think are far more onerous. 
 

I have a version of the Audio Kinesis Swarm and the benefits are significant. My system pics graphically show the differences between subs on and subs off for both frequency response and room modes. My system is all analog and I imagine DSP could flatten it even more. Imaging and depth are also improved and even more so if you can go stereo.
