A slight (?) bit off topic, but looking at those tall towers brings up the subject (again) of point source versus line arrays. In fact, we had a discussion of that subject at our all-day-yesterday "System Hop," in which we travel from house to house listening to different systems for (usually) an hour or less eventually moderately lubricated (us, not our systems) by adult beverages. We do this every quarter or so. Try it You'll like it!
Back to my off-topic subject. Some manufacturers argue strenuously in favor of point sources (like Lowthers) and give all sorts of technical reasons why they "must" sound the best. After 60 years as an audiophile (and inveterate classical concert goer), my ears tell me that the best modern sound comes from linear arrays and open baffles. From there it's merely (hah!) a matter of application--'stats vs. planars vs. hybrids vs. cones.
Listening to the Brahms German Requiem (original vinyl: EMI, Klemperer) on my GR Research LS-9s with servo bass really brought it home to me yesterday. Having that magnificent orchestra and chorus envelop the room was what I have been after all these years. I could hardly talk afterward. Oh yeah, the music was pretty great too.
Again, to my ears at least, there is just something marvelous and "right" about the sound possible with the LA/OB combo that is just missing with point-source/closed-baffle approaches. And it's not even close.
I can come up with some good guesses as to why this might be, but I'd love to hear from someone who really knows.
