model:1514d 15" dvc 4 ohm sub
pros: very efficient, cast aluminum frame,good owners manual,came with gasket foam. had a decent amount of t/s info available. good general box designs included. versatile mid"Q" design. good connectors
cons: only 14.5 mm of xmax,trade off on low bass for efficiency sake. only 350 rms watts. tend to get muddy with higher power.
opinion: a good entry level subwoofer when you catch them on sale. they work in lots of different boxes. just don't expect miracles and this sub will do great in a budget system. break in time was about 1 week to get any reasonable low bass out of them. these subs wont break windows in low quantity's but they wont break the bank either.
