I mentioned this in the Definitive Technology speaker thread, but a few years ago I bought a pair of BP7001s that come with a 10" 30 ohm powered driver attached to rwo 10" passive radiators and powered by a 1500 watt amp. Well one of the subs was bad so Chet at DT sent me a new driver and a new amp, it was the amp that was bad, so for two years, I have had this 40 pound driver sitting in a box collecting dust.
So last weekend I am shopping at Ultimate Electronics and they have a damaged Def Tech Prosub 1000 (driver was punctured) for literrally pennies, since I have this powerful driver at home, I figure I'll put that one in. Well the issue I have is the driver that was in the Prosub is a 10" 4 ohm driver and the amp is only 300 watts, while the driver I want to use is a 10" 30 (thirty) ohm driver (the 30 ohms was confirmed by Chet at DT) and was made to handle 1500 watts (especially made for peaks above 750 watts)
My main purpose of this sub is to use it as a sumpliment to my center channel speaker only, using the speaker level inputs (which means the crossover is fixed at 80hz and I'll have the center channel crossed to my seperate SVS sub at 40 Hz so this sub will only handle 40-80hz for center duty only. This way my center bass frequency can keep up with my 7001 mains.
A few more thoughts, the driver in the 7001 is the same exact one in the supercube 1 subs and those also come with a 1500 watt amp. The dimensions of the supercube 1 has a total cubic volume of 1.172 feet while the dimensions of the Prosub 1000 is a cubic feet volume of 1.31 feet (almost the same) my concern is because the amp is only 300 watts and only has one 10 " passive radaitor as compred to the two PR
in the supercube ones, and the vast differences in ohms am I foolish to install the 40 pound 30 ohm driver in place of the 10 pound 4 ohm driver.
I understand that the 30 ohms driver will be easier to drive but require alot of power to reach the same levels as a 4 ohm driver with 300 watts. but since this is gonna be a mid bass driver I won't need that much power.
Sorry so long, I know very little about subs and would appreciate any help.
