For all you DIY subwoofer guys looking for a killer deal on a killer amp, someone on ebay is selling a bunch of used Crest Pro7200 amplifiers.
For those not familiar with the brand, Crest Audio has been one of the premier bands of professional touring amplifiers for at least 40 years, built to take the most punishing environments, such as an outdoor summer jazz festival, and keep on working. AFAIK
, they do not make any “budget friendly” products and typically new models are only available through pro audio dealers at list or near-list prices.
The seller on ebay has been auctioning off a large number of 7200 amps since the beginning of the year. They were originally asking over $500 for them, but the price has been steadily dropping along the way. Currently they are asking a mere $305 for these beauties + $50 shipping. That’s practically a give-away for an amp that originally listed for $1800!
These 7200 amps are EIA rated at 590 watts stereo @ 8-ohms, 1000 watts stereo @ 4-ohms, and 1650 watts stereo @ 2-ohms.
FTC ratings for 20 Hz – 20 kHz should be in the 500 watt range at 8-ohms, 900 watts at 4-ohms, and 1500 watts at 2-ohms.
Bridged power is 2000 watts @ 8-ohms and 3300 watts at 4-ohms.
I bought one for my bass guitar rig but unfortunately haven’t been able to play out with it yet, due to Corona madness. (I wish I had waited, I could have saved $75!) I contacted the seller ahead of time asking if these were touring amps or from an installation. I was told they were touring amps.
Typically I avoid pro audio gear that has toured, but you can see from the pictures that they are in very-good to excellent condition. The pictures you see at each auction page is the amp you will be buying.
I did connect the amp to my home practice rig which has a small EV ZX1-90 PA speaker, which has a sensitivity spec of 123 dB. With the gains all the way up and no input, the amp is dead silent. That’s very impressive for any amplifier connected to a high-sensitivity speaker.
The main caveat, the front-panel LEDs are ridiculously bright. I’m talking “light up the midnight sky” bright. I covered mine with 8% window film, and it’s still too bright for my taste. Depending on your installation situation, you may want to just cover them with black electrical tape (I recommend 3M).
