Re: Retrofitting Altec 612 cabinet for a 4pi build
There you go! That's a fantastic idea!
Evan Flavell (Zilch) would love that cabinet. He'd be proud!

Cabinet design, port placement and internal standing waves
Damping material placement
Altering Dimensions
I realize you are talking about reducing the inter...

You can read the full backstory on this thread on DIY Audio.
I was encouraged to a...

Re: Download the app, of course
Hi, the ESLs are different from conventional speakers as they present more of a unified sound stage and less of a point source type of sound. They do both direct and reflected sound and are a bit tricky to set up and honestly will not work well in all roo...
