In Reply to: Pro Amp without a fan for subs posted by Dwight St on April 8, 2006 at 21:09:33:
I assume you are using the sub for home cinema purposes thus the reason for the unacceptable fan noise. In this case I have found that the Yamaha P series amps (the P7000 in particular with 3200 watts RMS) offers really exceptional power / price / weight performance and along with their highly efficient EEE engine and switching power supply technology hardly generate any heat thus keeping the multi-speed fans almost always off. And even when the fans do startup, they only turn for a few revs at very low speeds producing no audible sounds. My setup uses one P 7000 driving an Audiobahn 18†in a 12 cf tuned enclosure for some really earthshaking effects.
(Note only the P7000 & P5000 amps have the switching power supplies).I have also use the Yamaha CP 2000 amp (2000 watts RMS with no switching power supply) that has only one fan with equally satisfactory results. I would tend to believe that the Yamaha P 4500 could also fall into this class with slightly higher power and lower distortion, but I have not tried it myself.
All of these amps can be purchased from eBay although the CP 2000 is seen much less often now-a-days
