Torn sound fronts

KingMeander

Hi,

So, during the weekend we had a bbq and as the speakers have been broken in over the past several months we decided to crank up the sound a bit.

So, with the Onkyo 705, the volume works a bit weird, as it starts around -50 and moves positive from there. At 0 to +2 or 3 it sounded ok. Once I got higher than that after a few minutes the two fronts (as those were the only ones being used) started to sound really torn.

I am not sure why it started doing this as the speakers should be quite capable of handling that power output. The reciever is only 100 watts possible while the RTi6's can work with up to 200.

The only thing I could think of was the reciever may have been overheating, though it did not feel that hot.

Would using the reciever biamp help this problem at all, or is it just that's the limits of the reciever?

I'm using 12 gauge monster cable as well.

Any help would be greatly appreciated,
Steven C.

i would never run the volume on a receiver in the + side of the volume... you're just asking for trouble from both the receiver and the speakers.. and as you found out.. one or the other had to give out. the speakers lost that battle.

if you like to crank your speakers in the future.. look for an external amp for your receiver and bigger speakers.. speakers and receiver both have their limits before distortion sets in and blows something up. that is the case in your situation.

think of it this way... would you take your car for a drive today and red line it for 30 minutes solid at 8000 RPM? I would hope not.. that's what you basically did to your speakers.. red lined them for a long time.

I imagine you were clipping pretty good at that level with a 100 watt reciever. It's the clipping that does the damage. You need more power if you want to operate at those SP levels. As a rule of thumb, you want to operate on the first half of the volume knob.

Awesome, thanks. I actually didn't know that as my old reciever hadn't had that issue...maybe it was a built in saftey.

even though a receiver or amp is rated at 100wpc, it's not always pumping out that much power.. as you increase the volume.. it's taxing the amps and power supply in the receiver.. the watts per channel may dip down to only 30 or 40wpc when pushed. and often times if a receiver is rated at 100wpc, that may be what it can pump out at short peaks.. not for a sustained amount of time.
