RE: ET LFT-8b in Harry Weisfelds system

sbrook---the woofer problem is a matter of the driver having a resonant peak way above it's 180Hz x/o frequency, which because of it's shallow 1st order slope is audible. Davey came up with a cure for it, adding a couple of electronic parts to bring the woofers response at that resonant frequency down to the point of inaudibility. He will provide the specifics for the filter he came up with if you ask him, I believe. It is buried in this forum somewhere too. The woofer problem is found in all three versions of the LFT-8.

The output level of the tweeter was increased in the "b" version of the speaker, in response to complaints of the LFT-8 and 8a having a too soft high end. Davey feels otherwise, finding the b version to sound to hot for his liking. Others feel differently, for the usual reasons.
