Why not horns?

Also, Macrojack, John Dunlavy was known for claiming that his later Dunlavy Audio Labs speakers were superior to his earlier Duntech designs precisely because the "new" (at the time) MLSSA system gave him the opportunity to measure far more precisely and implement his theories to a greater degree.
This was late '93, early '94.

Anyway, back to horns!!! (didnt want to hijack this thread, haha.)

Mapman, the original Ohms Walsh driver was not a one way speaker, there were different segments. Though it might not have used an electrical cross-over, there were indeed mechanical cross-overs. Still a brilliant idea, that I think might has been improved upon by the German Physiks DDD, which appears to be a single driver. I think we're getting off topic now.

OK, back on topic, German Physiks has a model that attempts to achieve full range with the DDD driver by horn loading it called the Unicorn.

Has anybody ever heard these? I always found a horn loaded Walsh driver to be a quite unique concept.

Here's a thread from last year that might shed some light on the subject. Please note the same few people chiming in then as now in behalf of horns. That indicates to me the need for a broader base of knowledge on the subject.Too few audiophiles are aware of the performance potential locked up in this technology.

I found this article that mentions both older and newer OHM Walsh designs compared to the German Physiks. The reviewer indicates that the $22000 German Physiks was no better than the $1000 OHMs. Go figure! They must have screwed up the horn part somehow! Horns are hard to do right, you know!
