Current Setup: Axiom M60 7.1 setup with an EP500 sub driven by an Onkyo NR3007 (which has two discrete LFE outputs). Due to SAF, the deal was I could get whatever speakers I wanted (within budget of course) but it had to be a 'clean' built in kind of look. The room is almost square, which I know is less than ideal, but it was the only place I could put the theater.
I demo'd the EP500 in the room before it was built, but as I was building a custom wall-to-wall floor-to-celing entertainment center, I had to get the speakers first, and then build the cabinets around them. I did the sub-crawl, and found the best place for the sub (up front), was off center just a bit. Ascetically we built it into the cabinets front and center. Unfortunately, when we put cabinets on either side of the sub (the top is open- see my build thread for pics) we lost a good bit of midrange punch. There's just not a good place I could pull it out and put it right now due to it's size.
Don't get me wrong, the sub will still bring down the house for those real low rumble/explosion type effects. It still impresses me after several years with it.
But when I listen to music, I do miss the punchy, feel it in your chest, drums I used to get when it was out in the open. I've tried running my front speakers at full range but it gets a little muddy- but I probably could tinker with this setup a bit more to see if they can fill in. Or add a second sub to augment and smooth things out.
Enter the compact SVS-SB12. I've got a couple of spots I could hide this bad boy. I've read good reviews of this sub, especially for music. The only knocks it seems to get is where my EP500 currently shines. The metal grill means I could park the back up against a wall or sofa and keep little fingers off the driver as well.
My question (if you're still reading) is would mixing a smaller sub from a different company be a problem? I can configure both subs idependently with the AVR, and I can still let the EP500 handle the real deep stuff.
