Small or large sub for music

dbphd,
Acoustical engineers have proven that bass response performance in any given room improves as the number of subs is increased and that the size of the drivers in the subs is much less important than the actual number of subs in the room. 2 will perform better than 1, 3 better than 2 and 4 or more is just exceptionally good.
Of course, these experts realize that there’s a limit to the number of subs consumers will allow in their home rooms; or at least that consumers’ significant others will allow in their home rooms.
Through research, they discovered statistically that using 4 subs in a room provided the vast majority of bass performance benefits of using many more subs did while still remaining a feasible number for home use if reasonably sized.
In your situation, I’m almost certain that using 4 moderately sized subs would provide significantly better bass response than 2 subs randomly placed with one behind each main speaker. I believe this will hold true irregardless of the price, quality or driver size of the subs you choose based on specific scientific research on this very subject and my personal experience supports this conclusion.

If you have a decent sized room and want state of the art bass response, I suggest you at least read the Absolute Sound review of a DBA (link below) so you can make a more informed final decision.

dbphd,

Sorry, I linked the wrong link for The Absolute Sound DBA review.

Here’s the correct link:

I also forgot to mention that the Audio Kinesis subs are positioned facing and within an inch of the wall. So all you see of them in the room is the attractive wood you choose covering the top, back and sides of each sub (connections are on the bottom).   I use the supplied spikes for each on my carpeted floor. My wife says they look like art gallery pedestals and usually has a vase of fresh flowers atop 1 or more.

Have you tried daisy chaining all four?

" Have you tried daisy chaining all four?"


m-db,

No, didn't think there was a need.  The Debra system's 1,000 watt amp has 'A" and 'B'  sub/speaker output sections, each with its own 'Left' and "Right' sub/speaker outputs, so  4 sub/speaker outputs total.  I run separate custom speaker cables to each sub  that are routed through the crawl space underneath my room.

Sorry for being so brief. I meant to say daisy chaining the four powered HGS subs via the Dayton's EQd line level (RCA) connection using each subs 1000 / 1250w amplifiers. 

I'm not sure of the ohm rating of the two HGS drivers. I'm assuming if they're anything below 8 ohms you may have presented the Dayton amplifier with a less than its combined 4 ohm minimum load which could affect the subs performance and possibly damage the drivers.

Blue Jeans or MonoPrice cable offer reasonably priced custom lengths of RCA cable.
