Current vs. Watts??? Need clarification.

Are you driving one set of speakers or are you driving two sets simultaneously?

Just to add to the mix that pre-amp overload may also play a part. Sometimes some form of attenuation is needed between source and pre. Especially if you are only getting limited volume adjustment.

Gentlemen, That is a great set of answers. Thank you.

To clarify a few things.

1. Beavis - I'm just driving the one pair of speakers. There is only one set of posts on this amp.

2. Viridian - It is interesting that you mention the S5e, as I actually had that speaker in the house for a month or so before trading up to the S8e (not enough bottom on the 5s.)and I did experience the same problem on at least one occasion.

3. Mlsstl - I have to confess that 1/3 is up pretty high on this system. I sometimes - foolishly - try to make up for either ambient noise or lack of detail within the system itself by turning up the volume. Although, as I've lived with the system for a while I learned it's limits better.

Thanks again. G

W = E X I X P.F.

P.F. (Power Factor in %) refers to the phase shift between current and voltage at various frequencies. Some speakers are more prone than others.

So, the more phase shift you have the more current required to achieve the rated watts.

A sufficient power supply will help sustain the voltage during larger phase shifts, and some amps are able to deliver more current.

I guess there are a lot of ways to skin a cat and some amps do it better than others. :-)....?
