Hi Vaughn,

and of course the whole readers here,

I am from germany..and my plan for a semiopen 2 x 12 back cab is to make it

closedback..but with a oval opening at the back.

Anyone knows which size or place this opening has to be???

More above..or more down under the speakerback???

 

By the way is it a good idea to choose the following speaker mix

 

ET65 plus Reaper 30 ( for a full 50watt soldano head)

or Reaper 30 plus Veteran 30 ( more equal power and output)???

Musicstyle: with strat and Lespaul

moderate Rock, clean blues, no heavy..no high gain sounds too much..

 

Thank you guys for all your hospitality.

 

Vaughns viedeos are damned good and gives a piece of background..

Holly

Do you know what the dimensions and configuration of the cab will be (vertical/horizontal ... speakers side by side or diagonal)?

Hi Vaughn,

thnak you for reply. Sorry when I only send the dimensions in german cm??

 

the 2x12er has 72 x 55 x 28 cm ( is it eventually then 1.75 x 1.35 x 0.68 inch

Ill mean width x high x depth.

Its just a little more like a marshall cab JVMC 212, but homebuild.

 

greetings Holly

Hi Vaughn, the configuration is plywood like a marshall JVMC but custombuild.
the cab is a 2x12 horizontal, speakers side by side.
greetings Holly

Hi, okay, so first, go for a good, light plywood ... Baltic birch or similar (it will sound good, and your back will thank you).  Next, the oval rear port:

When you state: "the 2x12er has 72 x 55 x 28 cm ( is it eventually then 1.75 x 1.35 x 0.68 inch)" ... I think your measurements actually equate to about 28" x 22" x 11".  First, I would suggest a little more depth in the cab - maybe go to about 35cm.  Now, for the oval rear port - if you want to augment the low-end with the port then make it apx. 1/3 the size of the cab back - in your case approximately 24cm wide and 18cm tall.  If you want a traditional open-back tone, then simply make it as large as is possible.

Hi Vaughn, that's great, of course you are right..the measurement is 28" x22" x11" ( I was wrong with the change

by cm to inch, sorry).

So your help is very efficient and I see you have all the ideas for a good tone. Thank you very much!

In that case I will start and take WGS Speakers for the future.

Good luck and again thank you for your help.

Best wishes to your ideas, Holly

I'd put the port right in the center of the cab.
