How do you get that nice (curved angle) on the vented horn system as don’t know anything about wood work?
Before I put my components (130A/LE175-HL-91/2402) into the L200 cabinets, they were in the University EN-15 cabinets (like the EN-12 shown but for a 15"). They sounded like cr-p with no real bass to speak of, even with all that twisting going on in the cabinet. The L200 cabinets were a vast improvement.
More pics. Maybe they'll help.

Hello,
I own a pair of Altec Lansing speakers in excellent condition, which I believed to be vintage 820A. Checking a technical catalog on an internet site 'voiceofthetheatre.com'), I realized that overall height of my speakers is only 104,5 cm (41 + inches) and is smaller than 47 + indicated in the 820A catalog. Is it a variant of 820A ? Could it be instead a non genuine Altec Lansing manufacturing with those different dimensions ?
I'm looking for any useful DIY info on the 821 cabinet - the project thread link above was a bit of a dead end, since all project picture links etc. weren't available any more.
If anybody on this forum, has pics, plans or useful links or tips, I'd be very grateful - THANKS!!!
Cheers
Peter
Anybody...please?
Altec made a mini variation of the VOTT for portable sound, I forget the model number. The problem has always been how get good bass from the speaker.
Most of the designs in this thread are from the 1950~early 1960s, They were in the first book I bought on speaker design. How do you get a big horn into a small space, the "K" horn was the best over all comprise, remember most everything is a comprise.
FYI, check here.
