Based on past observations with my sound meter, I rather suspect that the bass drum peaked at over 100 db in one place near the end of the piece. Now, if very much of that number had been that loud I would have had to put my fingers into my ears to attenuate it, but in this case the whump was musically and emotionally very proper and effective. If you are getting only 70db from 1 watt, you'll need 1000 watts to get 100 db. Perhaps you will want to work very hard at making your listening environment very quiet before you get serious about CD's and/or DBX records as reproduction of deep bass at 1000 watt levels would entail considerable expense. BTW, does anyone know the comparative effect of 100 db of low bass compared with the same power level (no weighting) in the midrange (re hearing loss, etc.)? -- Chuck Forsberg, Chief Engr, Computer Development Inc. 6700 S.
