Testing waters for these. Matching front stage in Cherry. They are bookshelf, but they are pretty big and have very decent bass on their own. I used a pair of these without a sub in another setup (they are -3dB at 55Hz). Selling because I basically have too many speakers, but held on to them for so long because I really love their sound. I bought them used but replaced all drivers and rebuilt the x-overs (Air core foil inductors, Sonicaps) when I received them to support the latest version of the tweeters. I bought them from the person who was building the cabinets for GR at the time (Brian Rutledge); they were his personal pair and he built me the matching center for them as well.
Midrange performance is where these shine as GR has the M130 woofers built to their spec, but GR's "fisheye" tweeter is also very well known for smoothness. Tons of detail, particularly suited to vocals, which is why I bought them. NOTE: they are true 4 Ohm speakers and really do need decent power.
Looking for $600 + shipping. You can't build 1 pair for that price unless you build your own cabinets and even then it would be $414 for the kit without the cabinets. They are heavy too, 38lbs each because the cabinets are reinforced 3/4" MDF. You can see in the pics the veneer is high quality. Pics are old, but they have not changed and have not been in regular use for a few years. Magnetic grilles, lined with "No-Rez" liner to keep internal vibrations to nearly zero.
