Hi, this is my father's Altec Stonehead DIY project.
He is 50+, and a litlle crazy in the head (I thought for a long time).
We experimented with differend drivers and crossovers for nearly a jear, build a pair of nice cabinets, and so here we are. The top is made of Belgium Granite.
For LF we use the Altec 416-8b, for mid Altec 808-8b with Stereo-lab 500Hz horns, and for HF the JBL 075 ring radiator. They sound pretty good.

you may well be right about him being crazy- most people have the roof outside the house. Looks like a super job on the speakers though :applaud:

Hi, thanks for your reaction.

-macaroonie you may well be right about him being crazy- most people have the roof outside the house.

it was my grandfather who build that roof in our basement, he was a bit like my father.

-SEAWOLF97Do they sound good as they look ?

Yes they do. Fisrt there was a sort of Altec/JBL competision in our house. I have a pair of JBL L220, and my father is a "Altec man". Until 6 months ago my JBL's were the best sounding speakers in the house. Then one day my father bought a pair 416-8b LF speakers and I changed/upgraded his crossovers. Now the sound is warm and open, the 808 drivers sound realy well.

You know me, Al, I like folk art, and that's some of it right there.

Dirk,

Nice setup. Could you post another picture showing the Stereo Lab horn and how it is mounted to the granite slate? Is it a 1" throat horn? What is your impression of it?

Thanks,
T.

Hi Mr T. here are the pics you asked for. The driver is a Altec 808-8b 1'' driver with aluminium diagram.
