Beryllium center for Avalon Eidolons

generally speaking A focal tweeter isn't easy or at least cheap to get. I know I had to buy some. And speakers are hifgly engineered products that aren't simply one from column a and one from column b attach to crosiossover at point x etc. I think you will run into trouble unles well versed in speaker design and building.

I meant getting the actual speaker, not building it.

Boobeb,
I have the Avalon Indra's and acquired the Kharma Cermamique CeCt-1.0 Center after seeing that an Audiogoner who had the Eidolons and was using the same with great results. It has been a fantastic match for my system. I know they do not come up for sale often, but; if you find one, you will be pleased with it's performance using the Eidolon's. I was previously using a B&W HTM1.
