With those two speakers running paralleled,the combined resistance is about 3.4 ohms.That is hard for an amp to drive. 8+8 ohms =4ohms.4+4 = 2 ohms.8+6= 3.4286 ohms.
Running 4 speakers from a 2-channel amp
I love the sound of 4 speakers playing at once around me. I've got a simple old SS amp, Luxman L507 (mid-1970's) that runs 4 speakers at once. I'm running a pair of Yamaha NS-1000x (6 Ohm) as mains, and a tweaked set of B&W 805Ns (8 Ohm) as B's.
I'm talking here about 2-channel sound, 4 speakers, not 4-channel surround sound.
I've been looking for a higher-end amp, but find almost all are two-channels only, with ports for only two speakers.
Some great old Luxman tube amps offer 4 channels, but only one pair at a time is available on the selector ("A or B," not "A and B"). One shop told me they could have one modified for me to be able to play 4 speakers, at only a small cost.
Another shop told me that playing 4 speakers at once, even on my current old Luxman, which has the "A and B" option, overburdens the amp and shortens it's life.
I wonder - can't we wire-up 4 speakers, say two on each side in parallel, like in so many car stereo setups?
Am I really limited to only 2 speakers with a 2-channel amp?
