Title: Wardsweb does DIY speakers
Post by: Wardsweb on November 23, 2009, 08:43:22 AM
This all started around Jan 2006. My DIY Brazilian rosewood JBL corner horns were nice but just didn't have the high end sparkle that I wanted. This after my custom Altec A7 Voice of the Theatre didn't were not that great at near field. Imagine that a speaker with a 15 foot bass fold not working well in my living room. So on to a new design.

Baltic birch and MDF with CNC bracing and kerf MDF sides.

I filled the kerf with some glass microbeads and spray the interior with rubberized automotive undercoating and add fiberglass batting. These cabinets are DEAD!

Added JBL 2235H woofers, Altec 802-8G drivers mounted to Altec 511B horns and JBL 077 slot tweeters. Used some perf metal covered with JBL blue grill cloth and they become speakers. Just in a raw state.

Years later I finally pulled the drivers out so I could veneer them. They look nicer being the focal point of my living room.

Here they are with three coats of DEFT lacquer on. More to go but they're already looking pretty good.

I turned some 3"x2" 6061 billet aluminum feet for them.
