Hey guys I was thinking of building an SPL enclosure for my MT since I hit only 142.8db on the new termlab playing music with my daily enclosure (10cu.ft enclosure tuned to 33hz using 2 6" Aero PSP ports) Will this enclosure be better?:

Why not try something in between. How about 7 cubes @ 34hz with 100sq.in. of port area.

What dims do you have to work with in your car?

i would say a major reason was the small amount of port area. just do a slot vent

i guarantee your not gonna like the way a 56hz tuned box will sound like on music

Yeah well this is going to be only a comp box, I will switch to my daily enclosure after competition.

you usually peak a little higher than tuning. here ya go this box would be a better place to start

^ the above box is better then the 1st subwoofertools box design. Give it a shot and let us know.

Too bad you don't live in Arizona. I'd let you hear my single RE MT 18 on 2800rms in 7cuft @ 32hz with 100sq.in of port. Just the other day I was told by a car audio shop that my single 18 was louder then (6) 12" T2 RF subs in a blow through that belongs to the manager. They said it sounded like 150db at least. I still need to get meterd.
