To do it or not to do it...2 FI-X'* for $153 or one IDQ...

What kind of sound quality should one expect out of an FI-X?

well Fi are known for both unbelievable spl and even more SQ. And they are handbuilt, with customer support bar none. Im not sure how much those subs usually fo for but $70-$80 for a handbuilt Fi sub is stupid cheap. Fi'* lower series of subs arent cheap (price, quality or sound wise) like Kicker, Rockford, ect. If i had the money i would get one myself! or 4!

Look threw this thread.

the Fi X'* are extremly efficient also.

You know, I love the idea, I love the concept, and if I didn't know about the IDQ I'd do it, but after what I've read about everywhere about the IDQ and the knowledge that I could have 2 of those in the future, I think I'm still sold on those. I want ultimate SQ right now and even if I get the Fi subs I'll constantly have the wonder in the back of my head haunting me of what the IDQ would have sounded like by comparison. I'd rather know that I got the best SQ for the money and that nothing else I could have gotten would have sounded better.

I agree with you. Not to mention, in the slight chance ur unhappy with the Fi X'* i dont want to be responsible. )

Hey X, check this out

Not sure if you know that guy, but he'* well known not only on that board but in CA circles here in Cali as he'* a regional promoter of MECA competitions out here.

Both of those are mine. Hell yes. I already replied to that thread and its awaiting moderator approval.

I sent him the payment for both of them. Can't wait to get these in. He recommended 400-800W RMS, but said that 1000W RMS should be fine so long as I turn the gain down.

Dude, u got one hell of a deal there! I hope u like them as much as i do. As for the gain, what i would do is use the gain chart to set it with a dmm making sure to set it to the appropriate level according to the chart for the amont of wattage you want to give the subs. Im happy for you X, let us know how u like them.

So when does the box build begin?

Box build begins once the 15" Hifonics and 12" Diamond sub get sold...

He recommended I line the inside of the box with fiberglass. Never used fiberglass before...
