I'm a new to proaudio gear.. EXPERT level in hi-end home and car audio...
We decided to use the crown XLS 2000 DC series amp to drive a single subwoofer for an outdoor aplication.. we needed high power and this seemed perfect
Sub- TC sounds LMS single 4ohm coil 1500w RMS 3k peak so we are running the amp bridged
The crown amp is fed a full range signal by an onkyo Integra reciever via front L/R RCA pre-outs and we are using the integrated LP crossover at 80hz
The amp display reads: MONO LP.. so i believe it is set-up properly...
To see the amt of power we were going to get, we free-air played the woofer with a 30hz test tone.. using the gain knob on the crown amp we drove it to what the LCD display said was "clipping"..
To our suprise we arnt getting anymore excursion than what we saw from our Velodyne 500w class A/B sub amp we had been testing with..... with 2000wRMS of GUARANTEED power I should have been able to bottom that sub out free air.. What gives??.. do we need a line driver to up the imput voltage? (like a samson sbox?) I didn't bother testing the power the sub was seeing.. but I can tell you it was no where near 2100w that the spec sheet says..
