Am I missing something here?


My MC352 arrived last week and I have yet to find speakers. When the amp arrived I hooked up an older set of Energy's. The speakers are rated 94db/W/M and 200W. Max. When seated approx 12 feet away I am getting a reading of around 92db on my spl meter, just before the speakers are about to explode. Rule of thumb is 3db increase for power doubled. At 200 watts I should read approx 116 db 1 meter from speaker. 94db/W/M are very efficient speakers. The thing that is driving me insane is the speakers I have an interest in are 88db efficient. (Revel F50a) Let's say the Revels handle everything this amp throws at them (350WPC). According to my estimation I should get a SPL reading of almost 3.5db less????? I would have to throw 700WPC to achieve the SAME volume as those crappy little Energy's? I was using a Harmon Kardon AVR 7200 before and got the same results. I knew the McIntosh would be much cleaner, but still I figured the MC352 would blow the HK away, It's almost triple the power!!! Am I losing my marbles or what??? Please help....Thanks

hmmm,why do you say that your energy's are crappy,ive heard a few pair of energy speakers & i thought that they sounded damm good & offered great value in this insanely priced hobby of ours.

if your looking for high spl's while running the mc352 the revels are an extreme mismatch ,any 4 ohm speaker that is 88 db is going to require a boat load of power,convert the ohmage of the revels into an 8 ohm load & you get an 85 db efficient speaker, bad news for spl's.

everybody has their own idea of what loud is & some will say that the mc 352 will drive the revels easily, it wont, from your post i gather that your looking for spl levels of around 120 or better, you have done the math & you know the revels wont give it up with the mc352.

your also comparing apples to oranges in speakers, the energy's are designed to rock & the revels are a hifi job designed to image.

the solution is simple, either look into a more efficient speaker or sell the mc352 & get an amp that doubles down in 4 ohms & push some serious wattage to the revels, either way the mc352 is not a good amp for the revels if high spl's are desired.
