As you may know from my other posts, I'm looking to build an S1 system with added super-tweeter and I'm looking for components, one of which will be a horn/lens combo.
I get the impression that the vast majority of members on this forum prefer slant-plate lenses over the conical "potato masher" types, but they won't do in this project--I need these speakers to look good in a fairly formal living room and my spouse doesn't go for exposed plates as a design element. Who knows why, but there it is. So the potato mashers seem to be a reasonable alternative based on JBL's angular dispersion curves, if I don't run them too high where they will become beamy. All transducers will reside behind a grille of some sort.
There happen to be a pair of 2301's up on eBay at the moment. Are there any specific issues with these versus the older design 1217-1290? Any others I should consider? 2370 bi-radial flat front, maybe, with no lens?
