My guess is that you won't gain much performance by going the passive bi-amp route, especially if you intend to use an identical Yamaha, because both amps would be running full-range. However, if the Yamaha amps can be bridged for monoblock configuration, resulting in twice the power output, then you could use a pair as single bridged monoblocks, one to drive each speaker. That would give you a bit more headroom. If you were going to use an active crossover and bypass the speaker's internal passive crossover's then bi-amping would be more advantageous from a performance perspective. There are some other possibilities worth considering, such as using a different, higher-quality amp to drive the mid/top with the existing passive networks; or using different hook-up wire to the respective bass and mid/treble sections, biwired to the same amp but optimized for driving the different frequency ranges of the two respective speaker sections. Good Luck!
BI-AMP/WIRE basics? INFINITY KAPPA 9
Help-
I am getting a pair of INFINITY KAPPA 9's and I guess they are notorious power hogs so I am considering bi-amping them. I understand they are set up for that, with jumpered binder posts. But I have no knowledge of what the benifits of bi-amping might be. Even if you bi-amp aren't the amps still working the entire frequence range? Is the benifit that the ohm load will be greater and therefore less likely to overdrive the amp? The speakers are rated at 340 watts RMS at 4-6 ohms, but I have read that it can drop to 1 ohm on certain frequencies. The amp I have is a Yamaha MX-1000 and I will be buying another identical one if I bi-amp. The specs on the MX are as follows----RMS 260 @ 8 ohms 0.003 THD / 295 @ 6 ohms 0.007 THD /330W @ 4 ohms 0.02% THD. Dynamic Power 450 @ 8 ohms / 560 @ 6 ohms / 740 @ 4 ohms / 960 @ 2 ohms / 1000 @ 1 ohm. What kind of performance increase might I see by bi-amping. And this may seem like a silly question, but what exactly is bi-wiring? Obviously if you bi-amp you need to run 2 sets of wires, but does bi-wire mean running 2 sets of wires to the
same amp? If you do, do you run them to the A terminals or 1 to A and one to B? It sounds like it could create problems possibly. My pre-amp is a YAMAHA CX-1000 that has 2 sets of outputs. I have 1 going to the MX-1000 now and one going to the line leads for a powered sub. I still plan on running the sub, but now I will need 3 outputs what do I do? ANY help would be greatly appreciated. I realize my equipment may not compare to what most of you guys run, but it is the best I can afford right now. Help me make the most of it. Thanks you guys (I appreciate the feedback on my "shipping heavy speakers" post. I have chosen to use DELTA AIR FREIGHT based on your recommendations. I think it will be safe,cheap, and fast)
