just wondering if this would be worth my time to build an abc box for my 2 12's. ive built one for a single 12 and it was pretty loud, but i only have like 300w/rms for both subs, is it worth it??? thankx in advance,
Chris

If you are using pipe I would suggest three 4" pipes.
That's three in the big chamber firing out three in the dividing wall, and three in the small chamber firing out. All 19" long for SQ tuning or or 8.2" long for huge street bumping. Anywhere in between is good.
Mount the ones in the dividing wall higher rather than lower, and make sure they have half their length in each chamber.
Then just worry about getting the airspace calculations right. It's mostly down to accurate ratings of the displacement of the sub...I have a cool formula if you want it.
