I recently purchased the Polk LSi7 Bookshelf Speakers, which are 4 ohm. Being a "newbie" to the audiophile
world, I am just learning about "nominal impedance" and such. I have a
Marantz SR7500 Receiver (105/ch x 7), which gives 8 and 6 ohm ratings,
but not 4ohm. I have read in on-line write-ups that it possesses a
high current amp, which is required for these speakers. The write-up also states that it has Current Feedback Topology amplification. I have 28 days to return the LSi7's, and so far, I can detect no "clipping" at high volume (Pink Floyd Animals sounded AWESOME). I now am looking to upgrade the Center Speaker to the LSiC, also 4 ohm. I must act quickly and pair them w/ the new Center Speaker to see if there will be any problems. I am driving the High Freq w/ the Surround Rear (Speaker C) channel, and the Low Freq w/ the Main (A) channel. My question
is: should I have any concerns driving these as L/R/C in 5.1
setup with this receiver. Any thoughts would be greatly appreciated!! Thanks so much.
