It sees half as much impedance because it has to supply twice as much current for a given voltage. With most amps the red speaker terminal swings back and forth from plus to minus while the black is fixed at ground potential. So lets say at some instant your red terminal is at 8V across 4 ohms and you'll have 2 amps of current flowing. If bridged to mono you'll be hooked to the other channel's red terminal which will be at -8V while the other is at +8V for a total of 16V across the 4 ohms which causes 4 amps to flow. If you ask 8V to supply 4 amps it is seeing a 2 ohm load.
Is it good to drive the magnepan 3.6?
I have 2 classe Twenty-Five power amp, and I just purchased a pair of Magnepan Speakers: model 3.6 and its rate is 4 Ohms speaker. I was wondering, if I "bridged" my power amp to function as "monoblocks" to drive a pair of magnepan 3.6. Will it cause the amplifier to "see" a 2-ohm load? Does that stress the amplifier's current capacity and will the amp be overheated?
Here is the power amp's rated output:
Rated Output :
8 Ohms Stereo: 250 Watts
4 Ohms Stereo: 500 Watts
8 Ohms Mono: 1000 Watts
4 Ohms Mono: 1600 watts
I don't have that much of experience on this audio system, so can any one give me some advice , please e-mail me.
Thank You
