Imperial Plans
Some Jensen stuff. While I believe the SketchUp files are accurate - use at your own risk.
The Imperial Corner Horn
If there was a Klipschorn competitor, this might be it.
(Though, there's a reason the KHorn is still in production, isn't there?)
The SketchUp model has an extra brace under the top shelf (Part A in the original plans) and inside the woofer chamber. Also an additional cleat at the bottom for the removable rear panel.
Bass Ultraflex 15
The Ultraflex for a 15" woofer. The original plans called for some silliness with a short add-in piece to trim the bottom. I tweaked the bottom so the silly little piece wasn't necessary. Also added another cleat at the bottom for the removeable back panel.
