John Reekie from Hifizine, the enthusiast's audio webzine, documented an amazing design in the following 2 part articles. This is a prototype speaker dubbed the "Mini Convertible," which uses drivers from Seas of Norway (http://www.seas.no/) and a miniDSP PWR-ICE125 plate amp for amplification and DSP crossover.  The prototype has a removable baffle for experimentation with different baffle profiles and cabinet bracing, but the final speaker will have the baffle glued (i.e. no screw holes).

The DIY speaker project is written up in a series of three articles covering design and prototyping, construction details, and detailed measurements and crossover configuration.
