Stereo & Electronics - Sail Panel Speaker Alternative

These could make an interesting alternative for the hard-to-find Rockford Fosgate 6.5" subs.

Opinions?

I doubt it, without more detailed specs. What's the frequency response, nominal (RMS) power requirements, and sensitivity? Just because it says subwoofer, doesn't make it a good replacement. With a max power rating of 200W, I'll bet it is REAL quiet at the normal power ranges the Monsoon amp puts out.

I was right in one respect. I found a spec sheet for these that shows a sensitivy of 77.3 dB/W/M. That's gonna be whisper quiet with a stock system.
