    QSC GX5 reviews

    GX5 500 Watt 8 Ohm Power Amplifier is rated 4.5 out of 5 by 6.
    Rated 4 out of 5 by from I would buy this product again and again This amp is cold even in the few hours of work. It is very quiet and low roar. The only drawback is its weight.
    Date published: 2011-06-09
    Rated 5 out of 5 by from QSC GX5 is solid. Running (4) JBL PRO single 18 entry-level subwoofers with (2) of these amps with no problems. These amps see a 24/7 duty cycle with a wide variety of listening levels in a Las Vegas lounge. They do the job cleanly and without worry. As other posts will point out, they are not light but I would rather have a bit heavier amp with the stability of a toroidal power supply.
    Date published: 2016-02-01
    Rated 5 out of 5 by from Good Value for the money Using this amp to drive two 15 inch subwoofers. Amp handles them without a sweat. Good quality build. Only con is the bright blue power on light; it is annoying, especially while watching movies using a projector in a dark room.
    Date published: 2010-11-29
    Rated 5 out of 5 by from Great Amp Worked perfectly with JBL 19cs and 26c speakers. Clean sound and crossover feature. This amp is very heavy. In my installation we used two of these. Make sure the rack can handle the weight of this amp.
    Date published: 2015-05-17
    Rated 3 out of 5 by from The fan is too noicy... Great power. I used it with two EV 15 and worked perfect... Great power but if the sound is too clear you can hear the fan of this amp as part of the music. Replaced it with the Crownd XLI 2500.
    Date published: 2016-06-13
    Rated 5 out of 5 by from Solid Amplifier Easy to use, robust and powerful. Great physical size and value.
