what is a Bose Bass Cannon anyway ? ...  :green:


I've got one of those sitting in my living room. The driver is housed in a 3.5' tube, and it has a bolt-on 10' extension tube.

Bose Acoustic Wave Cannon System. The driver portion is labeled AWCS-1, 8 ohms.

Anybody have any info on these?

Now, maybe you don't, or shouldn't, grab the ribbon for far-harpsichord, nor the hot condenser for snare-kissing... yet often we do.

Is the cannon a 1/4 wave distance mounted speaker in a tube?

I'm not sure if it is a 1/4 wave distance setup, but it looks that way from the odd distribution of pipe length. I need to thoroughly read that article to understand the concept.

The driver is facing the short length of pipe at the lefthand side of the picture, right at the junction to the long length on the right.

By the way, that guitar amp build looks rock solid.

Thanks!  :grin:

The chassis and transformers are taken from old Executone power amp. I put couple of extra 6L6's instead of rectifiers. Unfortunately, I had to remove that impressive looking capacitor because it is rated for 450V only, without it the amp looks not so impressive. :(
By the way, mouse pads made of great stuff to damp tube vibrations!
 :razz:
They may be used, I suppose, to damp vibrations in tubulr speakers, but I doubt they can do that.  :cool:

Hmmm... Leslie used an electro motor to rotate tweeters. What if to move the piston in a pipe, like in the automobile engine? One more comb-filter-effect device!

 :grin:
