Just hooked up my HTR-5550 and balanced it with the AVIA program. N26 mains, N-center, NO SUB YET (PB12 on the way) Using the speaker balance in AVIA I get the following levels: -18db volume (85db Avia) -28db volume (75db Avia)(Movie volume for my liking) -33db volume (70db Avia) -31db volume (comfortable TV watching) Maximum volume on this system is 0db Does it seem that for movies I will have enough power for the dynamic sounds (headroom I think it is called) given that I only have 18db more volume left above reference? This would mean that full volume would be 103db (I think that is correct not sure). Can the db level exceed the full volume in dynamic situations. I notice that the RMS power is 75watt but the dynamic power for an 8 ohm speaker is 95watt?
