Hi Folks: Thank You very much for the feedback regarding my query about whether I should use the 4-ohm or 8-ohm taps for my Herey II's. I haven't got off my lazy can to switch back to the 4 ohm taps yet, but I will do this shortly. Anyway, I was watching the power meters on my amp (McIntosh 2505) during a listening session earlier this evening. At normal volume levels, the meters indicate that the amplifier is producing less than one watt. Yes, you heard right and no, that isn't a typo. At about 50% of full volume (almost ear bleeding in my room) it develops +/- 12 watts. And this is an amp that is conservatively rated at 50 wpc RMS, and probably closer to 70 watts from what I'm told. Needless to say, I don't have the cajones to crank it all the way up. I've used the amp with other speakers (Fishers, 'stats I believe) and those meters really danced, even at low volumes. So what is it about horns that make them so inherently efficient?

Hello, I picked up a used pair of Heresy II's on eBay about two months ago. All of the literature that I can find pertaining to this model states that it is an 8ohm speaker. But when I unpacked this pair, one of the first things that I noticed is that on the back of each cabinet it says "nominal impedance 4 ohms." So, here's the question. I am driving these with a McIntosh 2505 (250 with meters) which has taps for 4, 8 and 16 ohm speakers. Logically, they should be wired to the 4 ohm screws, but they sound much better on the 8 ohm leads. Better dynamics and they play louder at the same position on the volume control. Will I damage the speakers, or the amp, by using the 8 ohm taps? Were all early Heresy II's (mine have a copyright date of 1986) 4 ohm, or are mine an anomaly? TIA. -Scott
