Axiom Home Page Forums General Discussion Technical Questions From a 1909, how much better SQ to 2809. To 3808.

Dave, you wouldn't notice "increased sound quality" with the incremental increases that you describe, because it wouldn't exist. At the specific average listening level that you propose of 75dB(which is in fact a good level for average use without causing hearing damage)and at a listening distance of 12'(in-room sound levels fall at a rate far less than 6dB per doubling of listening distance), I calculate that the M80s will be using about a tenth of a watt. Brief split second peaks(say 20dB) on the most dynamic program material with the widest dynamic range would use about 100 times that, i.e., 10 watts. This is easily within the limits for audibly flawless amplification of any of the typical HT receivers with ratings anywhere in the 100 watt area. Adding incremental increases in maximum power output which amount to about about 1dB or less at each step can provide no benefit if the available max is already more than sufficient. Unused headroom is simply that: unused.
