I would like to build a speaker similar to the 4343 monitor. I have most components except for the 2307 horn and the 2121 10" driver.
Probably could build some short round horn to temporarily substitute the 2307 until eventually one surfaces on ebay.
The 2121 is probably much harder to get though. I saw in some similar earlier thread some proposals. Some suggest to use the 2123. That pops up on ebay from time to time too. Now someone offered me Electrovoice DL-10X as some possible alternative. I wander if anyone has used these drivers and could share some experience.
(hope it is not considered offensive to ask this question in a Lansing Heritage forum; actually most stuff I have is JBL and Altec!)
