I know the feeling .....None of the yamaha stuff i have owned liked my klipsch....With my marantz they make sweet love, perhaps down right dirty sex !

I due believe I have a fair understanding of what you have all so kindly shared with me ! I did try bi-amping them earlier before my first post, and they definately sounded better...without any doubt. The increase in sound quality started me thinking about impedences and crossovers. A then I began to question my thoughts ....and got myself in a tizzy. Just out of curiousity, does anyone know what order of crossovers each driver uses ? (1st 2nd ...4th). These speakers seem almost magical ! I have always found I liked speakers that used 1st order more. I actually these Klipsch so much they probably will end up as the main speakers on my old gem Levinson amp. My guess is the use a 4th order because crossover frequency is so low for the tweeter.

So basically.... The when the bind post straps are on, the total impedance averages 8 ohms. When the straps are removed each section would about 16 ohms. I assume that the drivers and there crossovers are connected in parallel to the inputs, not in series, as then the crossovers would not function properly. Just so everyone understands where I am coming from....I have a seven channel surround amp that I only use three channels of (L R C). I can control the crossover frequencies to each channel. The amp(s) say 8-6 ohm load. In the amplifier manual it does tell me how to bi-amp a speaker. The amp is a Marantz NR-1601.

Okay....I read my speakers owners manual again. I have RB-61's, the owners manual for it says bi-amping is possible, but it does not give any more info other than that. The RB-61-II manual,(available online) says bi-wiring is possible. Knowing the minimum and maximum impedances for each driver section would help alot.
-
My amp is not rated to drive a 4 ohm load. The idea in bi-amping was a little more power and cleanliness. I am not sure....but I do assume that as I am able to control crossover frequencies to each channel(I don't know weather or not the crossover frequencies are applied before or after the signal is amplified I would assume before), that each channel would only be amplifing the necessary frequencies for each channel more or less. I would love to know the impedance curve for each section individually (binding post straps removed) and together. I have no desire to take chances with my amp or speakers.

Thanks speakerfritz ! Duh ....I checked the manual and it says nothing about bi-amping...it just says bi-wiring is possible ! So i guess it's a no go for bi-amping ! Thanks again for the wake-up call !

I have a pair of RB61's I am thinking about bi-amping with my HTR as receiver allows it. (I only use L R C ). Now my question is the RB61's are rated as an 8 ohm load. Is this only when binding post straps are in place ? If straps are removed does the speaker become two 4 ohm loads ? I measured each set of posts and I cannot get a reading for the top posts, bottom posts read about 4.7 ohms, with straps in place it still reads about 4.7 ohms.
Why have flat speakers if Audyssey is going to roll them off in the treble?

When I run audyssey on my amp I actually brings the settings up in the treble range....Like + 4.5 db at roo16 khz and lower treble settings vary from +1.5 db to +2 db. Ithink audyessy calculations vary wildly by room and speakers. I use this amp mostly for music (90%).
