Thanks to all who responded so far. I should have probably asked for speakers marketed within the last 10-15 years Nah!! because I always thought the Rectilinear 3, and the original large Advents sounded natural were easy to listen to....but that is ancient history
The results so far have been interesting. with Magnepan MMG getting 5 hits, and the 30 year old Spica TC-50 getting 3. Epos ELS-3 were about 2. However, this thread is not intended as a survey.
Occasionally, you see a pair of Spica TC-50 for sale on AG, and just recently a pair Angeluses with their flying nun design.
Is Spica still in business, or has someone bought their inventory of drivers??
