I have been building speakers since the seventies. The work of Neville
Thiele, Richard H. Small and J. E. Benson had yet to trickle down to the
DIY community. Things have changed!
This build is composed of an elliptical, bent plywood and barrel back
design maintaining the volume dimensions specified in the plans. The
electronics are housed in the top for easy access.
Initially the sound was much too bright and fatiguing. There are three
systems in my home and i found the same result with all three.
Disconnecting the tweeter did not elevate this. I have made this mistake
before and began to systematically strip out the silver plated wire
replacing it with Cardas Crosslink for the mid. The result was a very
smooth and laid back.
The bass is glorious and the supra cable remained.
The tweeter was an issue. Several wire combinations were attempted
before deciding on Crosslink before the crossover, Cardas for the point
to point on the board and Belden 18Ga mil-spec silver plated copper from
the board to the tweeter. A strange combination but it works. Before
this modification, the silver plated wire created highs that were all a
sibilance of F’s and S’s or at the other end the sound was like someone
had thrown a blanket over the system with too much copper. In the end a
3R5 attenuation resister was used giving the appropriate amount of
detail and air.
You have come up with a beautiful design that can be tuned to builder’s
