Ok here goes.
Is it actually bad to add a second sub to my system that doesn't match the primary sub in size or watts or is it just not preferred?
I have a 20l x15w x12h three walled sunken living area open to the rest of the house above.
The setup is all in a floor to ceiling full wall built-in bookshelf.
Sharp 65" SE LCD,
Pioneer Elite SC-67 AVR
Pioneer Elite BDP-62fd
Mac Mini media server and Apple TV
Klipsch RB 61 II l/r and RB 52 II center
Ceiling Klipschs for the surrounds
Paradigm 14" DSP-3400 Sub on the front wall below and right of the TV
I'm 90% happy with the way it all sounds now but every time I tweak something it just gets better.
I sold the Yamaha Aventage and got the Pioneer SC-67and that really helped everything. (probably just a setup issue and aesthetics but still its gooood)
I finally ran the PBK (had it for a year) on the Paradigm sub and wow. What a difference! Really tamed the response curve. No more BOOM
My wife even likes it a LOT now.
But while sounding MUCH better, the PBK software revealed a significant suckout of response centering at around 100hz that it helped but couldn't totally fix.
My thinking was to attempt to round out the sound by getting another smaller Paradigm PBK enabled sub (maybe a 10" or an SE) in a sealed cabinet to bring different strengths to the game.
My logic told me that the big 14" DSP-3400 with the ports would handle the bottom end and then a sealed 10" could add punch to the middle and hopefully fill the suckout hole at 100hz
I don't have the room to go bigger than a 10" cabinet because of location constraints and that is even pushing it with the wife. I am even thinking about a Milleniasub just for its form factor which would really be the best scenario as I could hide it between the couch and the short wall.
The DSP-3400, though huge, fits perfectly in its dedicated cubby next to the equipment shelves and really it sounds good now... but I know it can get better.
Then I spoke to a salesman about all this who told me no,no,no. That I shouldn't do this. But was he just trying to sell me two new Sub 12s?
So... back to my question... is it considered death to have two different subs in the same room - or is it really no big deal and just might work.
It would be nice to hear from the theorists and hopefully someone who has tried this as well.
By the way my AVR has 2 sub outs for the main zone if that makes a difference.
