I'm looking for something that can handle 1500 to 2000 watts RMS daily at 1 ohm and can play low. My box is 2 cubic feet after subwoofer and port displacement tuned to 32hz. I got about $250 to $325 to spend.
I have a nice very stiff suspension old school DD 2512 Dual two with the cast basket these things can take the power a hand built beast not Chinese assembly line ...for $250 shipped it has a dimpled dustcap..but not bad
I bet you'd be pretty happy with that Blem FU Audio 1500Ti. It is hand built in the US also. I have been very happy with all the FU Audio subs that I have ran.
