This way you'll be able to proudly tell people you built them yourself :D and they'll be even more impressed!
2xT30 (20", 3012LF)
2xT30 (21", 3012LF) in progress
4xOtop J-array (Beta12, melded/straight piezos)

Thanks for the reply Bruce. looks like I'm building 3015LF boxes...at least 4 of them. now to narrow down that perfect top.
Build them as wide as you can transport. From what I've read in the reviews, 30" seems to be a favored compromise without going the full 36". Although, the sensitivity of a 36" T48 is pretty phenomenal.

Build in process - 2 WH6, one Alpha 6a loaded, one PRV Audio 6MB250-NDY loaded

Two 2x6 shorty SLA Pro's
One T39, 16", 3012LF loaded
Tall AutoTuba, 20" wide, 2x 8" MCM 55-2421
TruckTuba, 8½" wide, 2x 8" MCM 55-2421

i just read through the plans and it seems that the Lab15 offers quite a bit more output than the 3015LF. am I reading that correctly? If it is almost double then I have no problem going that route. more output per cabinet is always welcome. price is not an issue. just checking with you guys again before I pull the trigger.

The LAB15 has 14% more Vd than the 3015LF, which would be close to 1dB more peak output.

The LAB15 is also a 6ohm driver, so at 50volts it's 600 watts, whereas the same voltage in a 3015LF is 450watts.

Four LAB15's weigh 96 pounds, four 3015LF's weigh 36 pounds.

The LAB15 does have the advantage in maximum output. Up to you if the cost, weight, and slim margin of advantage is worth it. If it were a permanent or semi-permanent install, I'd go with the LAB's. Otherwise, I'd choose the 3015LF. Ultimately up to you though.


There's waaaaaay more to be gained in maximizing cab width than there is in driver choice.
