while considering speakers i put together a set that has the mains at 8 ohms and the center and rears at 6 ohms. (they are sold this way by MFG (Axiom) I'm under the impression that all speaker ohms must match? my receiver is "100 watts per channel,min. RMS, driven into 8 ohms at 1 kHz" on all channels in surround mode. there is a switch for 4-6 or 8 -16 ohms on the receiver. are you aloud to mix ohms like that? will i be able to drive the speakers(with mixed ohms) without frying my receiver? what is the proper ohm setting(4-6,8-16) on receiver with those speakers(main 8, center and rears 6) and ohms if its OK to mix? should i play it safe at get all 8 ohms speakers? if its so bad why would they sell packages like that? help!! maybe i just don't understand.

Funny I just participated in a very similar thread in Axiom's forum here .
In short, absolutely no problem whatsoever in mixing the speakers with different ohm (impedance) specs. Also, you should set the receiver's ohm switch to "low" (4-6 ohm) if and ONLY IF the power amp's safety shutdown circuit (thermal or overcurrent) ever kicks in. Most receivers can get away with the "high" (8-16 ohm) setting without a problem, when driving efficient speakers like the Axioms. Setting the ohm switch to "low" will reduce the max power output of the receiver (see the link above).

thank you, that link helped allot. im just concerned about spending 2k and then having to spend another grand on a receiver 2 days later, the wife would absolutly FREAK! by your statement and reading that link i should be ok with the setup. after reading and comparing 4 other brands the axioms (price/aesthetics) are the leading contender for me. of course i still have to listen to them.
Actually, while you are in the Axiom message boards, just search on "Ian" and "Alan" as usernames. Ian is the founder and chief engineer of Axiom; Alan is a former editor of a major Canadian audio magazine and currently the "resident expert" for Axiom. Their posts are so informative and enlightening! I guarantee that you will learn a lot in a short period of time.
I do not think you will be disappointed with the Axioms. Good luck!
