Recommendations for FI Q Series for Odd Shape Enclosure

[Sound Wave Mobile]

Hello,

I'm looking for some suggestions as to a couple different options I have in regards to using 2 FI Audio Q Series Woofers. My vehicle is a 1992 Camaro. I've already built the enclosure that will house the woofers. The enclosure was built using MDF and Fiberglass and is 3.85cuft gross. I've built the enclosure to be as large as possible being that the space is rather limited in the rear well of a thirdgen Camaro. I figured I could always fill the enclosure in with something to make it smaller if needed, but I'm not sure what that would be yet. I figured I'd cross that bridge when/if I need to. I'm looking for recommendations of whether I should go with 10'' or 12'' woofers and whether it's possible to go ported rather than sealed. I'd love to go 12'' Ported, but I may not have enough enclosure volume for that.

I haven't ordered the woofers yet, but would like to order them early this week based on feedback from this post. I think I've included all necessary information to describe my setup and desired results, but if I haven't, please let me know if there's additional information needed. For convienence, I've included the specs for the woofers at the bottom of this post. I would really appreciate all the feedback I can get. Thanks in advance.

Goal: Tight/Loud Bass for a variety of music, such as Rock, Rap etc

Tuning if ported: 32Hz Preferred

Woofers: Two FI Audio Q10 or Q12 depending on recommendations from this post

Amazing post!

Haven't gotten to hear the q series yet but I'm eyeing them all the time. If it were me I'd go 2 12s in a sealed box.

Agreed I am tuned in waiting to hear also.
