I am interested in the 15's you like better, as I am just beginning my horn journey and experience is quite a money service.
How bout a good deal on those terrible 416's
I like the Altec 416, it is far from terrible and i like them in a vented box used up to 800 hz crossed to a good tractrix horn and 1" compression driver. My Altecs are not for sale i horde speakers.

A real sleeper 15 that is modern is the Celestion 1530. They are better then the Altec in the midrange when I compe them but won't go as low in a bass reflex. There are others, Eminence Delta 15, peavey 1508, TAD 1601, JBL 2225, all have a place where they are good, many others, the 515G Altec I use in a folded bass horn mono system up to 300, it is excellent for that

I would say some of the differences between some of the older and newer large cone drivers were the efficiency that the old driver had to have to work with the lower powered amps available at the time. It is the difference between a light weight cone and a very heavy damped cone used in most professional application. Now we have very stiff suspensions to handle the power loading and heavy cones for both power handling at elevated level and larger motors to handle high power. Some of the m-roll surround used today are so stiff it is unbelievable. One company that I never seem to see mentioned here is the McCauley line of pro audio speakers, another high power handling speaker. The TAD cone loudspeakers are very much the analogous of a JBL as they had the same designer. The TAD 15" are really a very good copy of the JBL 2225 at a much higher cost.

yes, some older drivers surely deserve their place in modern hifi systems, - many modern drivers are very good too, many are the lower end from pro manufacturer where power handling isn't the emphasis

here is a modern compression driver that I like a lot for high treble - it's from Celestion too.

I recommend using these little drivers from 5K up regardless of what the manufacture says. If you want to crossover lower and sacrifice the top octave extension a little try the Dayton polymide 250 driver at Parts Express. It's around 50 dollars and sounds pretty darn nice down to 1200 HZ in a good horn.

I guess most of 1" should be used over 3k regardless of what the manufacture says

I have used the JBL 2470 and TAD 2001 down to 500. Many others 800 or 1200. Using a horn that loads it properly is recommended though - Here is the Dayton 250 polymide driver - reflections above 10k are bad - it sounds good 1.2K up even in a short horn like the SEOS waveguide. That's what it was in when I measured this

ok, thanks. i have a pair of the jbl CD horns, the ones in the studio monitor, and want some nice drivers for them. don't like the harsh sound typical of most horns.
