QSC RMX 850 : Ettoi's user review
« Very good amp for a sub »
For two years he drive in bridged mode on a 4 ohm subwoofer with a 38cm JBL no problem, I removed the clip and the low pass filter and it grows very strong, very low. I tested broadband is good but not great. The fan "Made in China" has quickly become very noisy, I replaced with a sleeve bearing fan without going through the Service as they would have given the same ... and everything is back to normal. Domestic manufacturing is neat and efficient. If you use I in stereo you will not regret your purchase is a great value.
