Full Range Merrill Driver in TriTrix Cabinet

[Philfr]

G'day,
Automatic plans do not work, especially on the site you quote.
I'am Phil on this forum.
If you want a small speaker, maybe a MLTL was a solution or closed box with subwoofer.

You're right, Scottmoose; I used the Tritrix enclosure, but made a new baffle to accommodate the Merrill DCA5.5 driver. Note that I moved the driver to the very top of the baffle. The Tritrix is basically a tapered transmission line (refer to drawing) and when I reviewed Martin J. King's Classic Transmission Line Enclosure Alignment Tables, the DCA5.5 driver turned out to be a good match for the Tritrix dimensions.
