I just received my new subwoofer (PB2) Tuesday. Before having this, I just had my 2 RF-25's hooked up and that's all. I hooked up the sub to my receiver with a cheap Radio Shack cable, set the gain to about 1/3 up and plugged in the sub. Turned on the receiver and started up RotK. It didn't appear that any bass was coming from it. Thinking it might be an issue of having the Klipsch set up as large, I switched out receivers as I lost my remote for the one I was using. Without the remote I couldn't change the speaker size. I switched over to a Kenwood VR-6060 receiver. Hooking it up with the same cable I setup the fronts as normal (instead of large) and set the sub to on. The other channels I disabled. I left them all at +0dB and the gain on the sub was still around 1/3. I used the test tones to check the the sub. Nothing intially, if I turned up the gain it would make a small sound but nothing massive. Thinking that maybe it was maybe the powerstrip, I plugged the sub straight into the wall. No difference. I then procedded to switch cables to ones I had used with my HTIB sub and they didn't make any difference. I then got out my HTIB sub and hooked it up. It won't make a sound at all not even the slight rumble the PB2 makes. I unhooked the right front as the cable was touching the sub cable thinking it might be interefering somehow. No change. I'm going to buy a better cable tonight but I doubt if that is what it is as the cables I have now worked before with the HTIB with this same receiver. I will also completely disconnect the left front and just play the sub by itself to keep anything else from being in the way. Does anyone have any ideas of what I've done wrong? I am assuming it is a setup issue that I just can't figure out. I have the PB2 to use the receiver crossover which I am not sure what it is as it is not documented in the manual. Phase is set at 0. I am using a coax cable to run from the receiver's sub preout to the PB2 input (can't remember if it is R or L but I tried both). Receiver is set to stereo sound and all eqs are turned off. Loudness and Bass Boost are also off.
