For those of you who find the MAHL's to be sibilant because of the efficiency mismatch here is your solution. So far tested on KLF-20's and Forte's where the more efficient B&C drivers can get ahead of the stock Klipsch drivers. I also have use this same exact set of resistor values on a complete speaker build I am working on and they realy even things out. No more fighting with those variable output L-Pads that drift and require cabinet mounting and access to the adjustment knob.

  All soldered assembly is plug and play and you go by the attached picture for directions. Price includes Priority mail small flat rate box.

  For those of you handy with soldering the parallel resistor is 4.3 ohms and the serial resistor is 5.1 ohms and refer to the second picture for what this means.
