Sub advice needed

I have a pair of Velodyne HGS-15s and a pair of HGS-10s.  Does that count as four subs, or do they need to be the same size?  Tim seems to think it does.  He's been urging me to give up my idea of separate pairs of subs for stereo and HT setups.

Do multiple small subs extend the lower end of the frequency range by multiplying the radiation area?  For example, might three HGS-10s be the equivalent of two HGS-15s with a total radiation area of 30" in each case?  I don't understand acoustic propagation well enough to know the answer.

If you go with four subs, they don't have to all be the same size or even brand.  I have two SVS SB13 Ultra subs and two Rythmik F25 subs in my 4 sub setup for my 2 channel system.  Completely overkill, but they are also used in my home theater system.

To the OP, you could get four Rythmik F12-300 subs within your price range.  It looks like you're using the Brooklyn as a pre-amp?  It appears to have two sets of outputs and your amp has only RCA inputs, so I'm assuming the amp is connected to the Brooklyn using the RCA outs.  You would need to get a couple of XLR Y splitters and then XLR to mini-XLR to connect the subs to your Brooklyn using the XLR outs on the Brooklyn.

You don't need a remote control for the sub's volume.  If your sub(s) is set up right, the bass will be there when it's in the music and it won't be when it's not.  You want to have the subwoofer set up to blend in the bass, not overpower the rest of the frequency range.  Once you have that, leave it alone.

veerossi, I'd skip it for now. You are better of with what you have than trying to fix yourself up with a sub system for that kind of money. The Audiokinesis Swarm is probably the best for the money at $3200 which is a great price for that system. Otherwise you would have to do something like two JL Audio Fathom subs the cheapest being $7000/pr. Do not do just one sub unless you plan to buy another down the line.

big_greg, can the Ultra be used as a master controller to output its DSP processed and preset signals to slave non DSP subs?
Are you able to simultaneously connect your two channel and your HT to the Ultra with the caveat of using the two channel or the HT one at a time?

If I'm not mistaken the JL Audio F and G series subwoofers can master control their more economical E series and possibly other powered subs with an XLR input. 


dbphd, in my room when I replaced a more than ample single Velodyne DD-18 with two DD-12 Plus' I gained an across the board presentation improvement. I attribute to a second sub reducing the rooms modes along with newer design amplification and certainly their far more advanced Plus Room Optimization and equalization. 

Crossover integration is the subwoofer industries unaddressed secret. Once you've heard it done properly you'll immediately realize that a single crossover point telling the sub to begin outputting is stunningly inferior to multi-band parametric filter frequency, level, and variable Q adjustability. 

big_greg, can the Ultra be used as a master controller to output its DSP processed and preset signals to slave non DSP subs?

Maybe?  It has XLR and RCA outputs.  I've never considered doing that.  The manuals should be available on SVS's website.

I haven't done that, I'm using outputs on my two channel pre-amp to send signals to the subs when the HTBP is engaged on my two channel pre-amp.  Doing it that way I lose bass management from my home theater processor.  I'll have to give that a try, that would be a better solution than what I'm currently doing.
