"Blackwood"
A
few years ago while in Tasmania, I purchased a rather nice plank
of Blackwood about 8" wide. This project was aimed at using
that plank. I had four Vifa M11WG's and a pair of Jaycar
120wrms 10" poly woofers, so an MTM+W 3-way seemed the obvious
choice. I chose a Peerless 811582 tweeter because of the 80mm faceplate,
it has proven to be a very nice tweeter.
Gumby's open back arrangement
was so nice I decided to do the MTM as an 'open-back' design. The
10" woofer was too wide for the plank, so the design needed
to have bulged sides around the woofer. For aesthetic reasons, it
was decided to trim the woofer with a ring of blackwood. Also, to
align the centers a bit better, and aim the woofer up away from
the floor a bit, an angled front was applied to the woofer section
As usual, a series x-o was used,
in this case a linked 3-way series x-o.
