damn, why???

concerts or did you just want to make something huge???

RacerXtreme · 23rd January 2005, 12:09 AM

That's not huge.........

This is huge:

They are the big Altec Lansing Voice of the Theatre (V.O.T.T.) cabinets.

They were first designed in 1945 and went on sale in 1946 if my memory serves me correctly.

I've got two of the A2's or four of the A4's - complete with wings.
Each A4 cabinet w/ dual 15's weighs 430 pounds. In an A2 configuration they are 9 feet wide. Got good casters (with reinforced stainless steel backing plates) so they roll around pretty easy.

Bought the entire P.A. system 20 years ago out of the George Burns Theatre when it closed. Used to DJ big weddings and parties with them. Some outdoor rock concerts too.

Why? ......... Why not? I like loud music.

I'm going to laminate the horn section of the V.O.T.T.'s and am installing 400 watt JBL 2225 15" woofers in place of the original 60 watt Altec 515B's (with Alnico magnets). The cabinets are going to be stiffened up internally, and some of the volume of the box will be reduced to make the JBL drivers feel more at home.

Eight JBL Pro woofers in those boxes ought to really crank.

I'll let you know.........

It wasn't intended to stand much scrutiny.

Guy,

Haven't you got off your sorry @ss and veneered those yet? C'mon man we've been waiting for you to stop dilly dallying so we get to see how good they look.

Oh, and those dual 18's. In a square box? Shame on you. Why didn't you build some oversized Ubangi's?

Something about not having the drawings I suppose.

Hope your Sunday was a good one.
Your friend,
Cal

i like it. why did he do it? because he can? why do we DIY anything, because we can.

how do they sound? do you get a good response out of them? what are the drivers?

RacerXtreme · 24th January 2005, 08:31 AM

Hey Cal,

no I haven't started working on them yet. We just got a foot of snow dumped on us and it's pretty cold here. Haven't got motivated yet, but I will. Hope to have them done by spring-time.

The dual 18 cabinets sounded really good. With the VOTT's and four 18's there was all the low end you could ask for.

c-ya

I still wonder what these JBL 2225 got over a real 15 inch subwoofer driver.
