The directed subs are very good. If you went to Doncaster this year, there was a blue 106 there with 4x 15" Directed subs the same as the ones that i have priced up. They were being run off a couple of Directed 1100d amps and he was knocking out about 14
b...not bad at all.
The specs on the subs are as follows:
Dual 4Ohm Voicecoils
350Watts RMS (600 Watts Peak) they will take much more though
60Oz Magnet
90db Efficiency
12mm X-Max
used for both SQ and SPL applications
in other words top notch for the cash. That Rockford amp would give it about 320 Watts RMS and about 470 Watts RMS @ 1ohm with another sub on it...for future upgrades
Let me know if you are interested in purchasing anything or would like more details.
