Hey guys. Trying to get rid of some excellent equipment that I simply no longer have a use for.

The first item is a QSC PLX-3402 PA Amplifier.

I am posting rough specs below, you can see complete specs and amplifier information here: QSC - PLX Series Amplifiers

16 ohms (20 Hz-20 kHz 0.1% THD) 1400 W
8 ohms (20 Hz-20 kHz 0.1% THD) 2200 W
4 ohms (1 kHz 1% THD) 3400 W

Signal to Noise (20 Hz-20 kHz) < -107 dB

Input Sensitivity @ 8 ohms 1.9 Vrms

Input Sensitivity @ 4 ohms 1.7 Vrms

The amplifier is in excellent condition, save for a minor surface scratch on the bottom of the amp, which is shown clearly in a picture below. The amplifier has been well cared for, and is in fully functional condition. Power cord is included. I paid about $1200 for this amp brand new.

Here are the pictures for the amp:

The other item that I am selling, is a Paradigm X-30 Crossover.
This is a fully active XO


HP 3x(pair) - 50Hz, 80Hz, 120Hz (stereo) - 12dB/octave

LP 1x(pair) - 35-150Hz Variable - 18dB/octave


1x(pair): Line level RCA (stereo)

CONTROLS(LP out only):

Phase Control - 0 - 180 degrees

Level Control - -70 - 0dB

LP Frequency - 35 - 150Hz

All 3 HP outs can be active at once. I purchased this at a local retail audio shop for $175+tax. I no longer have the original AC adapter, but a suitable variable AC to DC adapter will be supplied with the unit. Also included, although not pictured, is the original single 20' shielded RCA cable that came with the unit. There are some very minor surface scratches, one on the top of the unit, in the upper left corner, and one on the front of the unit, at the very top, between the two dials. I have circled both scratches, although the front one is VERY hard to see.

Here are the pics of the XO:

I would like to sell them both as a pair, for $850 + shipping. This is a great deal on some great gear. I will also consider selling them seperately, cost for the amp would be $750, and $100 for the XO (plus shipping). I will accept buyers for both over seperate, as that's what I prefer to do. I am NOT interested in ANY trades, so please don't bother emailing me or messaging me with trade offers. I need money, not trades. You can either respond on the forums or simply email me at [email protected] for a faster response. You can also message me on AIM, my SN is drakhi

I have been a member of these forums for over almost 7 years, but I really haven't ever posted much. I am quite active and have been for a number of years on car audio forums such as caraudioforum.com caraudio.com sounddomain.com and carsound.com so don't worry about me trying to rid you off. Just trying to get rid of some gear I no longer need. Thanks!
