Ultralight,
I have also been following this thread and waiting for the new 8" sub design to be finished. I have built and owned 6 different GR designs. Epiphany 20/21, LS-9, Super V, X-LS, X-Omni & X-Statik. All of Danny's designs in my opinion, lean to the warm side ever so slightly. Full rich midrange with excellent bloom and resolution.
the "Wedgie" bass and lower midrange will most likely depend on the (pending) sub woofer design, location in room and settings on the amps. The "Wedgie" rolls off at 200HZ so I don' think use as a stand alone monitor (without a proper sub) is an option for most users.
The 12" twin OB woofers in an H frame is the best option available to date but it is a "full size" design and may not fit into everyone's room décor ideals.
