this is done with an adjustment in the receiver named Input Level Adjustment or something similar.

I don't know that I'll need the extra power in my next room.


The amp i am using for my front drivers is rated for 1200W @ 2ohm, the amp i'm using for my rear drivers is rated for 500W @ 4 ohms.

The front amps is a Krell FBP300cx, the rear amp is a krell KAV 250A. My normal volume is about 90-95db in the room, with peaks well over 100db... My room is a great room that is about 17feetX18feet..


Clean power is the most important thing, Clipping is what does damage to speakers, not power....

With that being said, i will admit, i have way more power than i need... But, i'm ok with that :~)

Would the artifacts added from a scratched cd or bad PVR recording be considered clipping or is there another word for it?
I always worry about the times when the audio signal is interupted for a moment.
Iphones and Ipods connected by wire are the worst.

Thanks. I've got a handle on clipping because of too little power.
I wonder if the issues mentioned above have the same effect. They can happen at any volume.

not if your amp (voltage source) can handel the input signal. The only time you would have a problem is if you are trying to push the amp beyond it's operating parameters.. You mentioned sudden increases in volume, and artifacts within the source. These are just inputs, if you have a substantial enough amp, you're LFR's will play much lounder than you would ever want them to.. I usually listen to my system at 12-15 or so.. Reference level on my processor is 32.. If that gives you a gauge as to how loud it gets... 12-15 will result in about 90ish db within the room... The only way i would measure the DB in the room at reference level would be with hearing protection. At that point, it would just be an exercise to get a number..
