Panasonic 37" Plasma, Onkyo TX-SR606 Amp, Kef 1005.2 Surround Speaker Package,Sony Blu-ray BDP-S360,QED Silver Micro Cable. I have this system up and running a while now and i would be grateful for some feedback on my speaker crossover settings.I did auto speaker setup with amp and had to ajust some settings manually but have no clue about crossover frequency.In the speakers manual the crossover frequency is 3khz,and on the sub it tells you to turn up the crossover frequency to 140hz,the actual setting on the amp for all sats is a crossover frequency of 150hz ,would this setting be ok or is there a strain been put on the sub or sats.ive heard you can damaged sats/sub with the wrong settings ? HELP
