I am modelling two setups..... two LMSR 15's vs two Ultimax 18's in a 500 liter (17.5 cubic feet) box tuned to 15hz. I get a slot port length of 4 by 24 inches wide for 56 inches long. At 1000 watts both of them seem fine for excursion, and port velocity is 17 which seems decent. The 15's graph nearly dead flat from 15hz up through 200hz at about 117db. The 18's taper off quickly in the upper and lower frequency ends but have almost 120db around 40hz.
Am I missing anything obvious?!!?? Just looking for someone to double check my work and make sure I didn't overlook anything.
I am thinking about powering them with an inuke 6000.
The 2 TC sounds 15's will be about $250 more than the 2 Ultimax drivers for similar performance..... If you had to choose which would you get?
