Bass Horn Project - Part Three

A Fully Horn-Loaded Loudspeaker Made Entirely From Parts And Materials Recovered From The Dump.

This is a continuation of Bass Horn Project - Part Two.

Part Three was supposed to be about constructing the third "throat" section of the Bass Horn.  Instead, the present two-thirds of the Bass Horn are now set up as the bass portion of a fully horn-loaded speaker in the barn attic.  The bass driver currently connected to the Bass Horn is a twelve-inch woofer taken from a KLH model CL-3A.  The woofer is connected to the crossover network also removed from the CL-3A.  The plywood midrange horn is connected to the midrange wiring in the same crossover and the Sansui tweeter is connected to the tweeter wiring.  I set the midrange and tweeter horns on a box so they are about the same distance from the listening area as the Bass Horn driver.

I am listening to the speaker powered by one channel of the Lepai 2020A Class "T" amplifier.  I have only one speaker like this right now so I have been listening mostly to monaural LPs recorded in the mid 1950s.  The sound is surprisingly good.
