It may not be appropriate to post here regarding the Lowther speakers, but ...
David Dicks has always been very hesitant to allow his speakers to be reviewed outside his own listening room. This along with NO return policy makes his speakers very tough to buy. On the other hand it must give great amounts of heartburn to hand off your stuff to esentially strangers to review in unknown settings, set-ups, and recordings just so they can post their impressions on the net. And obviously in this game, the reviewer will always have the last say.
At least a couple of folks from the Decware forum, including Steve Deckert himself, endorse these speakers. Again placement is reported to be critical. IMO a decent speaker, let alone a great speaker, shouldn't be fussy regarding placement, set-up, source, or playback volume levels. Yes, each of those factors would, should affect how the speakers perform, but a good speaker should still sound good.
At the recent Midwest Audio Fest I heard several different Fostex based speakers (Omega, Terry Cain's TQWP Abby's, and Madisound bass horns). Each provided, to my ear, some of best sound of show, and at a reasonable price. Funny, but with all the different vendors there and high efficiency being emphasized, I don't recall any Lowther based speakers being there (aside from Welborne Labs AER's). Is the grandfather of all high efficiency drivers ready for retirement?
