    I'm wondering if I'll have sufficient amplification for running 3 M&K s150s (89 sens./4ohm) and 2 M&K 550 surrounds (8ohm) clean (minimal distortion) at reference level.

    I have a denon 3802 (rated only w/8ohms and 6 ohms on the specs) running the center channel and the 2 surrounds & a denon POA 5200 (120x2) for my 2 fronts.

    I don't want to run out and get new amplification if I get these speakers. Please give me your opinions-

    The denon will power them although the M&K's will sound better with more power! I powered my M&K's for a short time with a denon 3200.

    I'm not familar with the 3200...Is it the same as a 3802 w/ a outboard 2 ch. amp?

    My Denon 5200 is rated a 200wpc x 2 into 4ohms which seems like it should be fine...It's the 3802 running 1 speaker @ 4 ohms and 2 surronds at 8ohms.

    I do aspire to get a good pre/pro set up in the next two years...in the meantime i dont want to be just barely "getting by"

    The 3200 is an older model. Something like 80x5. The 3802 should be fine.

    Shouldn't be a problem. Give it a try, the receiver will more than likely shut down if it is overloaded but you would probably have to play it at loud volumes for an extended period of time.

    You may know this but it is best sonically to match all your speakers, at least use the same brand if you can.

    This is interesting stuff. Opens my eyes a bit!

    So, theoretically, let's pretend I know NOTHING about Ohms (I know some, but not a lot!). I do know that the "standard" seems to be 8 ohms. So, if I run an 8 ohm rated speaker with a 8 ohm rated amp, that's a perfect match, correct?

    My receiver does 8 ohms on all channels. I am interested in buying the 150 series M&K speaker system. All the speakers in that series are rated at 4 ohm. Is this good, bad, or indifferent? I currently own a Yamaha 2095 receiver.

    Any suggestions on what I should do? I'm glad someone brought this up because I had no idea the 150's were 4 ohm! I thought they were 8!

    Is there a good reason why M&K chose 4 ohm? I guess I just don't understand. Anyone care to help me out?

    Thanks!

    Chris

    Cool, I just noticed that I can switch to 4 ohms on my Yamaha 2095. So I guess I could drive the M&K 150's okay. I love this receiver, but I do know I'll need to upgrade my receiver to get the most out of the M&K's. Separates are my next upgrade.
