something, not sure

I know Cone + Port firing in to another ported box, is called a "Bandpass Series double tuned Box"

That I think is 6th order quasi

I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

4th order t lines I build all the time, well, usually when I build t lines

It looks just like a folded horn. IMO it sounds best

looking forward to how it goes goremaster :)

Since you have 4 18's why not something like this? :) Adding some angle to the inner-walls so its narrow at the start and wide at the end would make up for "lack of room" to keep the t-line at the correct size for 4 18's.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

the reason im not going to do the 4 18's is because im not going to recone them and if they blow have to take them out and recone again... i also work at a audio shop and im going more towards all rockford product. and if i do that its going to be maybe 4 t1 10's or 12's or 2 t2 12's. the main reason i dont want 4 18's is the weight. i've droped from close to 400miles a tank to 260miles with how it sits now. and i believe 4 t1 10s would look sexy how im thinking on doing the mounting of them. plus i would only need one 2500bd and i'd use 2 kinetic 2000 batteries so it would drop almost 500pounds

I think there's an issue with your truck if you lose that much mileage.

You're spending too much time idling/reving and doing demos :P

I'm planning on using a 4" subwoofer to build a t-line. I think it's fs is around 52hz; because this is higher than the fs of most woofers being used in a t-line, should I tune it higher too? Or should I still tune the box to my desired frequency? Right now my box would be 8.3 ft long with a "port" area or 15.2 sq in, which seems pretty fricken big for a 4" woofer.

masterbation is free, and even saves you money.sorry but someone had to say it

sorry, Jimmy...beat you to it (no pun intended)

LOLDON'T get a wife. Best advice I never got, and now it's too late <_<

My build: 12" DCON in a dorm room.

New/current build: 8" woofer, custom amplifier block, fiberglassed speaker pods
