In Reply to: Altec 825/825 cabinet improvement posted by Ron B on January 31, 2007 at 19:01:36:
I added about 2" of concrete behind the flares of my 825s.Before add ing the concrete,screw in a bunch of 1 5/8" drywall screws(being careful that they don't go thru the front)so the concrete has something to grip onto.I also added extra bracing to the rest of the cabinet,The more the better,but you will probably have to change the port size to keep the same tuning.
A alternative if you are going to use a sub(LABhorns work well) you can cut the cabinet in half,using just the front horn.A back chamber of about 1 cu ft works well with a 416-8a,although open backed sounds good too...
I recently tried a pair of JBL 2205as in them,sounds better than the Altecs...Sounds better than my round horns,too,even though they are the same flare as the Altec cabinet.:-(

Greets!In which? Better how?
TIA,
Hi!The JBL 2205a sounds better than the Altec 416-8a in either the cut down Altec 825 or my round horns.Maybe I need to send the Altecs to GPA for refurbishing? Altecs sound muddy...
The Altec horn sounds better than my round horn...:-(
I don't want to hijack this thread,and I need to do some measuring before we discuss this further,so I will start a new thread in a day or two...
Greets!Please do, you have me curious. For sure a 416 shouldn't sound the least bit 'muddy'.
