*Crystal-clear highs blend nicely with mid and even low level sub-bass (lower bass than I expected from a 6.5" speaker.) *Glass Fiber Composite woofer has very sturdy construction

*Tweeters a bit too high, but that can be corrected by changing jumper position in crossover (or adjust EQ settings.) *Crossover boxes are HUGE. I had a hard time finding room to mount/hide the crossover boxes, but the electronics inside gets the job done.

I had first heard the Fanatic Q 4" set in a friend's car and pleased with what I heard. So when I got the truck I decided to go with RF Fanatic Q's. I have them installed in the doors with the woofers mounted in OEM locations (lower door) and mounted the tweeter on the sail pannels where mirror controls would be. I personally think these are some of the finest speakers I've heard in car. I have them powered from an MTX 4244, and they set up a warm, full sound stage up front. With the woofer properly mounted in the door the low end was remarkable in that it sounded like a subwoofer playing at a low level. The high end was equally impressive, though a bit too harsh for my taste. However the crossovers do have a nice feature that I use to soften the highs a bit. There is an attenuating jumper that where you can set the volume for the tweeters at 0dB, -3dB, and -6dB. I keep mine at -6dB and the highs blend in nicely with the lows.
