Hello Jose
I heard very good things about the Bethoveen designed by Mr. Linkwitz. The special thing about his design is the active Crossover at line level which buffers first and then separates freq. while correcting the drivers function to be finally perfectly flat, this is done by a complicated array of opamps at line level, you can see a functional diagram at his site, extremely interesting.
The part that atracted me the most to this design was the use of one amp per driver directly connected to the speaker terminals, avoiding coils etc. In his triamped system he recommends simple chip amps (Gaincard style) for each driver, I was of course thinking of using tube amps for mids and tweeters but gain discordance was a problem, and I didnt want to tinker with such a complicated and succesfull active Xover desing.
I lived for a while with Lowthers on open baffle on top of Altec 416, Bazzilla style (bought the plans but strayed from the original design) and realized open baffle is not my cup of tea, at least untill a get a bigger room!
