Looks real good man. Cant wait to hear it in July.

Just as a tip: I've been told from a respected competitor that staggering the ports to where they aren't symmetrical causes subs to load funny.

you mean on the single 12 box... that may not be an issue as my buddy is just a minimal daily bumper and I dont believe it will mess with anything.

My comment was more directed towards SPL and situations where the sub is being highly overpowered. Just something to keep in the back of your mind.

yes, completely agree, that single box is a buddies and he is happy so its all good... now on my setup i'm concerned with the subs in such close proximity at these angles... i'll just keep an eye on the cones and see if they flutter or move out of phase with each other.

i believe my tuning is a bit below 50 hz right now, which puts my peak in the low/mid 50's, which may be pretty decent for this car and type of setup...

Believe it or not I prefer setups that peak high; lows are overrated, imo. With my current setup the highest that I've gotten it to peak was 44 hz and it's making me miss my 50hz setups

weird.. never heard anyone say high freq > low freq..

unless they're a meter humper.

nice build.. why didn't you just do it in one box...

I am to a point. For daily I prefer a flat response so that the sub plays more musical, but for SPL a high peak feels more uncomfortable to your organs than a low note. I could sit in Snoopdan's truck that does low 150's at the headrest on music at 33-35 hz all day and the low note doesn't phase me. But, as soon as the song hits a strong high note my lungs start to feel a little weird

i'd rather sit in mid 50's @ 29-35 hz. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

COOL. i guess i was asking for a reason behind building 2 boxes, advantages/disadvantages.. but whatever ***.

my back didnt want to deal with another 70lbs to carry //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

and I think two boxes may help reduce cancellation (if thats even possible, given what i'm trying to do here) and there are alot more walls to two boxes than one so its probably quite a bit more rigid just the way it is.

If I could swap out the four 12's for like six L7 10's i'd do it in a heartbeat though, easier to work with and I can fit them better in my car //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

the vehicle is going to determine the peek freq. more so than the tuning of the box.

hey, the builld looks great! I have one question, why 2 boxes? im not trying to criticize I just wondered because Ive never seen 4 subs like that b4
