I use simple resistor capacitor filters that I put between the amplification stages of vacuum tube amplifiers and do away with the speaker crossover and all its problems altogether. If you major in physics you can calculate the values of the resistors and capacitors involved. the resistors should be equal to the square root of the product of the output impedence of the driver tube and the input impedence of the output tube. These values need not be that exact. The capacitors should have a capacitive reactance equal to the resistance of the resistor. First order crossover is one resistor and one capacitor, second order is two resistors and two capacitors, etc. Make a high pass filter for the amplifier that drived the tweeter and a low pass for the midrange. Reverse polarity of tweeter terminals if you use second order. I do not know if that will help in the future.
Bi-amping???????'s
I currently have a pair of b&w 605's with a Kenwood Km-z1 amplifier (6x115) and a Rotel 960ax pre-amp. I am in college and running on a tight budget. I was wondering if there would be any significant advantage to using 4 of my channels on my kenwood to power my 605's, as opposed to 2 (the B&W's have bi-wiring posts) If I were to do this would I simply split the outputs and run them into multiple channels on the amp? I have done some reading about bi-amping and it refers to adding additional cross-overs, ect..... Any info would be greatly appreciated.
Thanks,
Kyle
