Hi, hoping to find some more information on this design. It had a proprietary bitumen damped 12" woofer and a 1,25" Audax tweeter.
The 12" looked through a wide rectangular "diffraction slot" supposedly to enable the heavy cone to extend to 1.5khz with a more even on and off axis response.
Given the aperture size I am a bit dubious as to how effective it was but can find no information regarding any dispersion improvement.
If anyone has information regarding this aspect of its performance.. the design paper by Spendor perhaps, or links to it, I would love to see them!! I understand hifi choice did a review and I think hifi news and may be others. Any links would be much appreciated!
