Oh, just the extended portion, yeah I was wondering about that myself. I originally drew them extending a full inch above the top, in subsequent drawings I've reduced them to 5/8 for that reason. I could reduce them even further if it might help the sound.

Easy for you to say
Actually, I think I could handle that. If I cut the bevel on the end before I beveled the sides of the strips it should work fine.

Hello,
I am planning to build a pair of the Castle type micro Towers. How is the brace
for the top firing EL70 notched. A sketch or drawing maybe?

Thanks,
Cambe

Dave. Does your remark about the Mark Audio speakers'"outstanding high frequency response" apply to his CSS EL70 design?

Yes,

The EL70 was the 1st driver Mark did with the tech that also gives the extended HF seen in the Alpair7 and Alpair12.
