    Altec Cabinets

    I have in the past constructed Altec 828 cabinets and also Altec 816.
    Looking at the designs I have I cannot see (or remember) the thickness of the wood used to make the curved horn flare on each design...
    Can anyone help with that?

    Thanks
    Tom

    Thanks for pointing that out...

    I have used the library (that's how I built the other speakers originally)

    It seems that this particular dimension is on the 1968 enclosure plan, but not the 1970 plan (the one that I have been using this time round).

    Thanks
    Tom

    I built one in the 1970's. A neighbor in college had two powered by McIntosh 240's. He had to put his bed in a closet loft they took up so much floor space. I lived in a barn on my parents' ranch with no one for 1/4 mile in any direction (except my parents). The barn was 60 ft. square with sloped ceilings. You could get the beer bottles we left in the exterior walls to dance.
    I found 1/4 " plywood was the thickest plywood I could forced into the curved shape. By cutting grooves in the top and bottom I got the sides snapped into place and glued. The print looks to have a greater dimension but they could have a mechanical means of bending the material with water. Perhaps two layers of 1/4" with "gorilla glue" to cement them together. The glue expands when wet and will fill any voids. My poor attempt prompted a return to the more manageable sized cabinet design (2'x3'x1') that I got from JBL for sound reinforcement. I think the Altec woofer with its' smaller voicecoil would have been preferable also. I had a D130 in it.

    Building Altec Cabinets

    I recently built some legacy Altec cabinets. For the curved horn section I used a product called 'econoKORE'. I bought their 3/8ths thick product. It worked great!

    Here is where I bought it.

    Do a search on 'econoKORE' and the page will pop up. Or here ...
