Disassembling Acoustic B200 combo

I have an Acoustic B200 combo. I use it for recording. I'm also a carpenter. I was thinking about building an Acoustic 361 cab which incorporates a folded horn design. I would remove the amp and speaker from my B200, build an enclosure for the amp and put the speaker into the 361 cab. It's basically an Acoustic 360/361, but with Acoustic B200 parts. Could it be done? The speaker would be permanently wired to the head just like a combo.

Well first of all the ACC 360/361 was a preamp only head (360) and a self powered folded horn cab (361) loaded with a 18" Cerwin Vega driver. No relation to your G.C. Acoustic B200.
That said, do not scale down the cab. It already has a high roll-off point. Whether the 15" G.C. Acoustic speaker will operate well in that speaker "plug" is unknown. Could be a fun project if you don't go into it with any expectations.

I hope you do it! For many many years I've imagined a 15" folded horn cabinet and this would be a good test. I think when I was in college my friend took apart the Acoustic cab, then scaled down the dimensions. It was 40" tall by 20" wide and 15" deep. There was a 3" wedge in back and horns top and bottom. I don't think it was so scientific but it looked cool lol.

Another bit of trivia: In the late 70's Kasino, a subsidiary of Kustom, built a combo amp with just the design you have in mind. It was tall and narrow, the amp was built in, and if you pulled the grill off you would see a mini folded horn design. It even had kickback wheels!

Please keep us posted on this super cool project!

Good luck! :bassist:

Many years ago I built a folded horn speaker based on the [Invalid or Expired Link Removed]. It was a challenge, but it ended up sounding and looking amazing. To truly be a bass horn, it needs to sit in the corner as it utilizes the walls to extend to its full length. I'm sure there are designs for smaller ones, specifically for a bass cabinet, that can be placed anywhere. Good luck, it should be an interesting build.

Oh wow, I remember those Klipsch Khorns! Only got to hear one time, and it was thunderous.

In the 70's and 80's a small company called Speakerlab manufactured a do-it-yourself kit with all the components for a Klipsch style cab. It was very popular.
