Another newbie blue-sky design question...

Assuming I'm aesthetically set on a 2-way smallish tower with one or two 5-7" woofers, is there and reason NOT to build a transmission-line style speaker? What are the potential drawbacks of MLTLs? Something like this from Troels Graveson.

Cabinet complexity (within reason) is not an issue.

There is no reason, except perhaps size. Every loudspeaker is a large set of compromises.

Here is our 2-way 6.5” MTM ML-TL.

A typically well-designed project from Martin -I'd expect no less. If I was nit-picking, I'd prefer a bit more suppression of the woofer's stopband modes in the 3KHz - 5KHz region (passive or active versions), but he's done a good job with very few components, and whether you'd hear the difference is debatable anyway. You could do a lot worse.
