@TitaniumTroy, As I understand it, Greg isn't developing a new line of speakers as such, but a new Reference model. Here is what I know about the new model thus far..
- It will be a larger 3 way panel consisting of a newly designed planar woofer, midrange ribbon and tweeter ribbon
- It will extend the frequency extremes beyond the GTA3r
- This Reference model will implement larger line source drivers, the overall speaker size will be approximately 90" tall x 28" wide
- This model will be in the $50k range
Knowing how good the existing planar magnetic & ribbon drivers are on the GTA3r, this new model should be outstanding. Hopefully Greg will be able to achieve similar frequency response to the Alsyvox Botticelli (ie: 22hz - 40kHz) with high sensitivity, whilst maintaining very smooth even response across the audio spectrum like the GTA3r.
What is noteworthy about the new reference model is, they will be massive & about the same height as the Infinity IRS-V's (ie: taller than the Apogee Full Range), which means there would be little to no floor to ceiling bounce. And because they are a dipole design where the front and rear waves meet and cancel out, there would be almost no sidewall interaction. So whilst these bad boys will need atleast a medium-large room to enable them to be brought well out into the room, they shouldn't be too critical re: room treatments. Exciting times at GT Audio Works!
