Question about Audio Players & Recorders
Hello: Can you help me? I'd like to know how to set the crossover frequency on the subwoofer.I have 2 "Q series KEF IQ9" speakers and the Model "PSW 3500 Subwoofer".My receiver is a JVC RX-5000VBK which has a subwoofer output. When connected it sends (unknown frequency) bass frequencies to the subwoofer without affecting frequencies to the 2 main speakers. There is no crossover setting and according to JVC all frequencies are being sent to the IQ 9's.Since the IQ9"s go down to 38 Hz and the Sub's crossover frequency seems to start at 40 Hz should I just not set the crossover at all (?) or would setting it at the first or second LED light-I believe 50hz-- or-- 60hz allow for a smoother transition?(My other settings on the sub are "music" " slope 24b" " low pass" )Thank you,Irwin Rubin

Onkyo to Onkyo, sub/receiver, problem fixed by inceasing volume on receiver. Seems the sub audio input does not pick up LF's below a certain output level from the receiver. So, guess I have to live with that. I only hope my nieghbor in the apartment below me can too!

SOURCE: Kube 2 subwoofer hum
The Kube Sub-woofer is earthed via its 3 pin plug. The Onkyo and other components I have in my system are not (they are double insulated). During normal operation, a difference in electrical potential can exist between these components in the system. I found that this potential was finding a path to earth via the audio cable and on through the subwoofer's earth. The path was via the earth portion of the audio cable and so gave the hum irrespective of volume levels set either on the Onkyo or the sub.
The fix is to ground the Onkyo to the sub. I used a length of electrical cable between a panel mounting screw on the back of the sub and a screw on the casing at the rear of the Onkyo. Try it out with a piece of cable manually touching screws with the bare ends of the cable until you find ones that give continuity( the hum will go immediately). I then crimped a small fork end electrical fitting onto each end of the cable which can be slid under the slighly loosened screw head and resecured. All I hear now is the fan on the Blu-Ray player!

The problem is you are dealing with two different brands of speakers, I know because I ran into the same issues you are facing now, I had a Bose sub matched up with two Radio Shack Satellites and sound was not balanced it was awful. Finally I broke down and bought a pair of Bose Satellites and I have never regretted it since. The point I'am making is that when you mix brands the sound will be unpredictable, the problem with most subs is they have a very low roll off frequency even without the crossover making almost impossible to match speakers.
