I currently run a DD 9515 on an American Bass 3000 watt amp. I'm thinking of switching to a more SQ based system (the DD sounds great but they are not the best at hitting the lows below 40 hz or so).

So, I'm looking into maybe 2 Fi Q 15"s, but I want the new system to at least be as loud as my DD while gaining a little in the SQ department. The Qs would be run off the same amp getting 1500 each, and I would get their upgrade for power handling (forget what it's called).



So whats your opinion, will the Qs have better low end, and will 2 of them be as loud as one 9515?


All feedback is much appreciated :)

ill give you 200 bucks for that 9515!

2 fi q 15s would be pretty damn good! i honestly dont think there is much better.

So you think the 2 Qs would be louder than the DD? Thats what I thought also but I wanted to make sure........


And I've already got a $350 offer on 9515.

2 15" Q's on 3kw? That sounds like a bad azz setup right there

2 18" Qs? At least you'll know you're going to get the output you want.

Definately think you'll be gettin the output your lookin for

consider a single Q 18" instead of the two fifteens.
also, if your DD isn't hitting low, consider a new box instead. something sealed, or ported lower.
Rarely is the response of a sub not a direct result of it's enclosure design.

dd9515 wont work in sealed. its an spl woofer.

You know how much I hate to agree with Bill But ^ He's right.
