I just picked up a pair of brand new SP-1s ( I know they are discontinued, but I got a good price ).
Anyway, I am not sure the powered sub is working properly. I have a Y-adapter plugged into my receiver, and then a sub cable going to the LFE in on the speaker. I have the switch set to auto. When I play a CD or DVD, the ligth on the speaker does go from red to green. But I don't seem to get any bass.
If I play the test tone on the receiver, when it gets to the subwoofer, nothing. If I go to the THX setup on a DVD ( like Star Wars Episode I ), and go to the subwoofer x-over test. It plays the tones and goes down, but you again don't get anything.
I have the main speakers set to small in the receiver. I have the bass being sent to the subwoofer.
Any suggestions? I certainly hope there is nothing wrong with the speakers as they are brand new out of the box.
