siucsaluki11 Posted February 17, 2010 Report Share Posted February 17, 2010 Well, to be honest, i dont know shit about bandpass boxes. I know they have potential to sound good and get loud. So im thinking of trying one out in the build im hoping to start in the next month or so (about damn time). The woofers are best suited for sealed supposedly, but they liked a ported box, got loud and low. But im in the mood to try something different, so heres this. It will be for 2 Clarion 12s, gettin around 400 each (supposedly 450 but i doubt that). If this doesnt work i can always just build a regular old ported box. The box will more than likely end up facing forwards firing into the seat back from my trunk, sealed from the rest of the trunk. Rear seat doesnt fold, but the box is pretty big, and theres no holes in the rear deck. So id be afraid of the enclosure blocking all the sound from getting into the cabin.

Ebes Posted February 17, 2010 Report Share Posted February 17, 2010 I had a similar problems with the seat not folding down in my car so what did i do I TOOK IT OUT lol. I still have the bottom part in and finished off the back rest with foam and carpet over it so all there is is the opening. Try to do something like this you arent hearing half the bass compared to if you didnt have the seat in there Quote Link to comment Share on other sites More sharing options...

siucsaluki11 Posted February 18, 2010 Author Report Share Posted February 18, 2010 Ya, im going for loud and musical. Ill be happy if it works, if it doesnt, guess i will just have to keep trying more and more. I still got a few months to read up though. Might buy the loudspeaker design cookbook to give myself something ill actually want to read and gain some knowledge.

Loudcivic Posted February 18, 2010 Report Share Posted February 18, 2010 from lookin at that chart it looks like your gonna peak at like 90-95hz which is high as hell. you dont want that at all cuz it wont hit no lows at all with a peak that high. and it finally comes to 0db at just over 40hz. so idk if your try for a high tl score cuz thats all that box from the chart would be good for Quote 2015 silverado crew cab nothing atm but soon...

rmzsuzuki89 Posted February 18, 2010 Report Share Posted February 18, 2010 I'm no expert by any means, but the sealed chambers look pretty big, and the ported chamber looks small.

uhoh_45 Posted February 18, 2010 Report Share Posted February 18, 2010 I'm no expert by any means, but the sealed chambers look pretty big, and the ported chamber looks small. x2 you want smaller sealed chambers and a bigger ported area roughly 3-1 ratio (ported to sealed) and your by looking at your port length it looks like your trying to tune it low which is what you dont want Quote R.I.P!

The sealed chambers tend to seem really small. For instance, my gf's two 10"s are in .7 cubes, into 2.1 cubes.
