    Default RM6000 Sub Setup Problems

    I'm looking for some help/advice. I have the rm6000 series which have been fantastic speakers for my small home theater. I have always wired them via the preferred method of running the fronts through the sub. I recently needed to buy a new receiver and on a budget settled on the Yamaha HTR-5930. I set up the speakers exactly the same but no matter how I tried and tried to configure the receiver I could not get an acceptable blend between the sat's and the sub. Atleast nothing like it used to sound like with the old receiver. It sounded to me like I was losing a lot of the midrange and when I would adjust the low-pass filter on the back of the sub I couldnt percieve any change in sound. I then decided to try the sub output on the reciever (lfe?) and plug it straight into the sub (looks nicer). This solution seems better but still not as good as it used to be, the bass is better but the mid's are still lacking. I know the manual explicitly says to NOT connect the sub this way but I could find no other way. Does anyone have any advice on how I should set this up to get optimal sound? Was it just a bad choice in receiver? Is it the sub? Is there something I am missing in the receiver setup? Any advice would be helpful as I seem to find so much confliciting information on the web.

    (Also, the on/off switch on the back of the sub seems to have three states (on/off/?) but I dont know what the difference between the on state and the middle state are - they seem the same?)

    Thanks,
    -Jeff

    Hi! Whatīs your setting of the speaker size? Large or Small?? If you go with speaker level setup you must use Large setting and Sub to off.

    The middle state of the switch is "auto on".

    Cheers

    I tried that and still wasn't able to get the blend right. I think part of my confusion is that the receiver had muliple bass settings (Basic Settings -> Sub Woofer: yes/no, then in Input Settings -> Bass Out: SWFR, FRNT, or BOTH) and none of them were quite right. I feel like I tried every conceivable combo to to no avail...

    whats the difference between Auto On and On?

    Thanks!

    When the sub is in Auto, and no signal is coming from the receiver the sub waits for a little time and automatically turn off. Although when the sub detects input signal automatically turns on. You could stay in auto and forget to switch it on and off your sub any time that you go to use your system.

    When connected through sub out, what crossover setting are you using? You could start with 120 hz to 150 hz range to try what is better for your ears.
    Itīs very important this setting to blend the whole system.

    Regards

    Perhaps thats the problem - there seems to be no way for me to adjust the crossover frequency on my reciever. Thanks for your assistance charliez! I may see if I can still return the receiver.

    Default PSW10 Setup problems

    I am having trouble with my PSW10 subwoofer. I seem to get random pops, rumbles, and other sounds from it. Sometimes it seems to work ok on TV , music, whatever, for a minute or so then it starts popping or making these other LF noises - unrelated to the sound source. It makes these noises even with the volume on the sub turned all the way down.

    My Setup is:

    Denon AVR1706 Receiver
    Polk CSI25 Center
    Polk M50 Towers
    Polk PSW10 Sub
    MTX Ceiling speakers in rear.

    I've read that the manual is in error and followed the advice to hook up the SUB out on my Denon to the LINE IN on the SUB (with a Y adapter). I run RG-6 in the wall to the sub.

    I've set/re-set my Denon speaker settings to SMALL; the crossover frequency to 80 hz, etc. and I've tried various settings of the crossover on the sub itself. I've tried reversing the phase. Nothhing seems to eliminate this noise.

    I'm am new to Home Theatre, and I am at a loss what to try next.

    The RG-6 cable in the walls was perhaps 15 feet in length. The external cables (from wall outlet to AVR or SUB) are 3 feet, tops.

    If you disconnect the sub cable, the noise disappear?
    Perhaps exists in the run of the cable any source of interference, you could check for that and try a different run, seems to be interference received in the cable. Another idea could be try a better cable. But first try to found the origin of the problem.

    Good Luck.

    Default PSW10 Subwoofer noise, pops, etc.

    Charlie,

    Yes, if I diconnect the sub RG-6 cable the noise disappears. There is no residual hum or ground loop in the sub that I can detect.

    I guess I'll try to feed the speaker outputs to the sub and then hook the speakers up to the output from the sub (per the manual) to see if that works.

    I switched my main speakers to small late last night from large. I have not had a chance to try it out yet. Is this what I should do based on my equipment or is more of a matter of personal taste?
    I like speakers that are bigger than a small refrigerator but smaller than a big refrigerator:D

    Scott, I think you did the right thing by changing to small. I have my rti8's as small with my xover set @60hz. What you have done is relieved the receiver from pumping more power to your speakers and allowing your sub to handle the lows, which eat up lots of the AVR's power. I believe you will have cleaner/detailed mids.
