What is the filter type and order on the PLX 1202 and PLX 1602 power amps ?

The filter type is Butterworth and the order is 2nd.

Thanks. I guess my next question would be, in a 3 way bass guitar cab loaded with 2 Eminence 3012LF woofers, what HPF setting on the PLX 1202 would be better, the 30 hz or 50 hz ?

What is the frequency response of your woofers?

Thanks for the data sheet. The usable frequency range of the LF driver is 46Hz - 2.0kHz. HPF setting on the PLX 1202 would be 50 Hz, closest to 46 Hz.

Ok, thanks. When running the amp bridged, should both channel hpf's be switched to 50 hz ?

No, only Ch1's HPF setting would affect the output. For best performance in bridged mono, Ch2's clip limiter should be OFF and Ch2 gain control should be set at minimum (fully counter clockwise). Use Ch1 gain control to set your desired output level. Below are suggested settings:

SW1: CLIP LIMITER (optional)
SW2: FILTER ON
SW3: 50 Hz (match with your loudspeaker's frequency range)
SW 4, 5, & 6: STEREO
SW 7: BRIDGE MONO ON
SW 8: 30 or 50 Hz (doesn't matter)
SW 9: FILTER OFF (doesn't matter)
SW 10: CLIP LIMITER OFF

I hope this helps.

Thanks for your help.
