Big, beefy, adequately "full-range" for my purposes, nicely efficient, and best of all designer / builder Duke LeJeune understands the issue of room acoustics / interaction and factors those concerns into his designs. All of his stuff is of interest to me and I'd love to be able to listen, and scratch this particular itch! - String

I went with a custom Planetarium Alpha setup from Duke. These speakers have integrated down firing subs and come with a seperate amp to drive them.
After owning them for several months I spoke to Duke and added a pair of satellite subs so now I basically have the Swarm. I have been listening to these speakers for almost a year now and am very pleased. I won't say you would be happy with a pair of Jazz Modules because one can't really know how someone else will judge a speaker. But I will say that Duke is terrific to deal with. And from what I have seen everyone who owns a pair of his speakers has nothing but great things to say about them.
My setup is a little more expensive than the Jazz modules. The base system was $6,000 (they might have gone up a little since I bought them) and the pair of satellite subs added another $1,200. It really is a sweet sounding setup. Cymbals and brass are so life-like with these speakers.
I'd like to think these will be the last speakers I'll buy. But I honestly felt that way with my Omega Max Hemps so never say never.
