    Stuck between a few different 18's... Psi, Fi, Aq?

    I'm doing a daily build, space isn't an issue. Will be ran on 2k. I'm looking for something that will smash the lows as loud as possible in the 30-40hz range, with extension into 25hz range.

    I've been looking at a few different subs, I don't want to go over $400 on the sub. Anything I buy i'll get all the extra options on.

    PSI Platform 2 18''

    FI BL 18''

    FI Q 18''

    AQ HDC3 18'' (Copper coils)

    I hope i've given enough details.

    FI Q is a very bottom heavy sub and rolls off pretty fast in the upper 40's, so it would probably be perfect for your application....

    That's what I was thinking, but I was leaning towards the AQ just cause of how loud it gets. But I'm concerned as to how "low" it will play, in say 6cuft @ 36hz. I heard they like to be tuned high, but my concern is that this will make it sound peaky, then drop off below tuning.
