    I bought some old JBL PA speakers very cheap. Both JBL G135A-8 15 inch full range speakers sounded pretty cool when I tested in my bass cabinet. Very bright and jazzy.

    Yet the JBL horns are blown on both boxes. OEM JBL horns are very expensive. The big decision is whether i want to save the PA speakers or just junk them. I was seeking advice from anyone who had experience with Selenium off brand horn D250-x drivers for about 40 bucks each. Or would you just junk the old boxes and keep the speakers?

    Thanks for your help.

    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.

    Basscooker: Went and checked out your webpage. Most cool indeed. I built my own little cabinet, not as professional as your. Only has one 15 inch...at a time.

    What speaker brands do you prefer to use?

    I wish I could find a cheap source the blown 2616H JBL horn diaphragms that came in the cabinets. Everyone seems high on the cost I have found.

    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.

    I had even considered finding some high wattage tweeter and replacing the horns all together. Something cheap but functional until you mentioned theses.
    Are these the ones you use?

    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)
