Speakers and Horns Question

I only see benefit in restoring them to original, or letting the boxes go and keeping the woofers.

*unless*

You are a tinkerer with the space and time, and hate to see solid pro-built cabs go to waste. Maybe you could use a pair of pa cabs for your group and want to try your hand at retrofitting these.

But both restoring and tinkering costs money; possibly/probably more than just tossing the boxes and buying newer used pa cabs.

 

You can get diaphragms for those horn drivers - kind of like a recone. "Selenium RPD250-X Diaphragm For D250" from www.parts-express.com!

The G135-8's are decent, but have a relatively short cone displacement (Xmax). They are very efficient and should help get the most spl out of low power amps (in a properly tuned bass cab). http://www.jblpro.com/pub/obsolete/G125-8_And_G135-8.pdf

 

I use MCM drivers, but each cabinet's design considers commonly available same-size drivers. Each cabinet will work well with slight port length changes with at least one brand name driver.

 

Might find better sources for diaphragms if you search on the correct part number... 2416.

Diaphragm replacement is the best way to go and should be less expensive than replacing the driver.

 

Replace the diaphragms mate they are expensive for a good reason. They are very good compression drivers indeed.X

 

Cheap parts are cheap for a reason. You will never regret spending the money to get the good sound, but you always regret the cheap stuff. (Don't ask how I know. lol)
