Help me build a 1X15 guitar cabinet please.

[Gravity]

I've used 10's and 12's and now I want to try a 15" for guitar.

 

I'm figuring on one of the 15" eminence drivers ... probably the Big Ben.

 

I play pretty dirty and the tone of the Big Ben was described as throaty. I like throaty.

 

 

A friend of mine has all of the tools and know-how to make something like this. But, I need to come up with a design first.

 

I do know that I want to make it wide and deep enough to sit beneath any of my three amps (a 100 watt head, a 50 watt combo and a 20 watt combo).

 

But, Is there any rule of thumb as far as dimensions go?

 

How does the size / proportions of the cabinet affect the tone?

 

What kind of plywood (or other wood) should I use?

 

Thanks:thu:

"Guitar Cabinets: Open Back (or infinite baffle)

 

Open back guitar cabinets are extremely easy to design, and typically require the least amount of construction material to manufacture. They have a very bright and full tone, and make great recording and live cabinets due to the fact that they have wonderful "room filling" properties.

 

One does not need to worry much about internal volumes, calculations, and other design criterion. Designs are mostly centered around form and weight.

 

To design these types of cabinets, start with the number of drivers. Most open backed cabinets contain 1, 2 or 4 speakers, but choose any number that meets your needs. Remember that twice the number of drivers doesn't necessarily equate to twice the sound output, due to acoustic coupling and standing wave cancellation in the room. However, more speakers is definitely louder due to the increase in cone surface area.

 

The design starts with the baffle. Make sure it is big enough to hold the speakers while giving at least an inch or two of clearance on all sides. So for a 2x12" design, the length of the baffle would need to be at least 2*12"+4 = 28 inches. The width would need to be at least 12"+2 = 14 inches. I usually design open back cabinets to be a physically small as possible, so that I use less wood and the overall finished weight is as little as possible. But the design criterion is up to the designer, and poetic license comes with the job."

 

i built a large 1x12 out of 'birch plywood' (4x4 sheet). it could easily fit a 15.

There are some other cool things on there, but the 1975 enclosure specs include a design for an instrument cab. Of course, it's optimized for a JBL driver.

 

Update: we just bought the wood for this, it came to two 24 1/2"

Sorry I can't post a link right now, but I've seen on Ebay a

booklet offered by either Hiwatt or Fane that gives plan specs

for many speaker cabs. The idea was to get "pro" cabinets made

with the least amount of wood sheets.
