The poweramplifier instructions for operation and kit assembly caution: if the speaker fuses blow, some distorted sound can be heard therefore if amplifier malfunctions, always check.
Beagle said: why bother well the hafler idea is a lot of fun, it is even 'natural' by some definitions i believe i read (way back in the 1960s) that if you used the hafler set-up to play a record miked with a crossed figure of eight pair, as was done with some early hmv recordings, that you would actually be playing back exactly what the mikes were putting on the tape with respect to spatial.

The hafler circuit is a passive electronics circuit with the aim of getting derived surround sound or ambiophony from regular stereo recordings without using costly electronics the dynaquad system works using similar principles.
All hafler products are designed and hand made in north america, using the finest components while every possible effort is made to reduce odd-order harmonic distortion, minimize phase shift and broaden the frequency response to ensure the signal transfer from source to destination is pristine and color free.
