Also I have to dissagree. You canot make a 8 ohm speaker magically become a 4 ohm speaker....Your not adding impedance to the speaker.....Your merely taking of the voltage.
Some people say that when an amplifier is bridged onto a 8 ohm load, it 'sees' a 4 ohm load. While it is true that the same current flows whether the amp is bridged on a 8 ohm load or a 4 ohm stereo load, the amplifier is driving a 8 ohm load across its outputs. A single 8 ohm speaker can never be a 4 ohm load.

Originally posted by Glen BYou were explaining the basic concept behind a speaker, and that's fine, but IMO did not answer the original question. I did not say that an 8 ohm speaker magically becomes an 4 ohm speaker. I was only making a caveat that some amplifiers when bridged will not safely drive loads of less than 8 ohms. This also includes so-called "8 ohm" loads that dip well below 4 ohms for a significant portion of their frequency range, in regions where there is a lot of musical content, and worse, present a severe phase angle (like B&W 800Ds). Such "8 ohm" speakers should be treated like they were 4 ohms. That is not magic, but fact as borne out by the impedance plot, and IMO a sensible approach.
Therefore my 370W amps at 4Ω should be good to goFarming looks mighty easy when your plow is a pencil, and you're a thousand miles from the corn field."Dwight D. Eisenhower- Bottom

I realize the dip in ohms.....the 8 ohm is nominal.....thanks
The question was originally about current. So, I explained the basics behind current and the electromagnet........I appreciate the debate tho....Ryan

Is 370watts enough at 4 ohms? That depends.. 370 watts will make your speakers go very very very very loud... That does't mean it will sound good..Main System:
B&W 801D
Emotiva USP-1 Pre-Amp
Chord SPM-650 Stereo Amp
Oppo BDP-105
Squeezebox Touch
Second System:
B&W CM7
Emotiva UMC-1
Emotiva UPA-2
Oppo BDP-83SE
Grant Fidelity DAC-09
