Danny Ritchie has announced his partially open-backed version of the RAW/GR Research RA-8. The yet-to-be-named speaker uses the same WWMTMWW arrangement and drivers, but opens the back of the MTM section and adds a GR Research SW-12A 12″ driver with plate-amp to the bottom. The additional 12″ driver brings the -3db point down to 25Hz, making it essentially a true full range speaker. The speaker is also shorter and the 12″ driver has its own sealed compartment, but the speaker is also deeper which likely makes up for woofer cabinet volume that would have been lost otherwise.

This is yet another speaker I am looking forward to seeing/hearing at the Rocky Mountain Audio Fest.

See details in this AC thread.
