Jim and Richard were friends ( RIP Jim - another on the list of greats lost early ). They certainly shared many design objectives; First order filters, minimum front baffle, time and phase correct. They differed on a few points but much more in common back then. … Until recently i maintained a set of CS 2.3 + in an ancillary system w Quad ESL 63, Apogee Stage, Magnepan LRS, Heavily modified Cornwall…well the list is long…. and what did i say about casting a wandering ear ? Probably the biggest Theil design departure is the philosophy of flat at listening position…. which presents as bright to some people in some systems in some rooms. Both Jim and Richard are measure AND listen guys…. these are just facts…
Vandersteen do make a coaxial speaker w cabinet in cabinet the VLR - Signature which incorporates the carbon tweeter. They are designed for near wall, stand mount and pair extremely well w Vandy subs 3 or used 2’s. A set of stands from sound anchor and away you go. Can’t say who but a guy w many platinum records use VLR on his mixing board…. It’s ALL fun…
Enjoy the music
