The tpl150 is really happy with a crossover in that 1200 plus range.
The 10 inches i use are jbl2123, which definitely are mids. That said for a 10 inch driver you want to push the crossover frequency lower rather than higher.
Knowing I would never reach nirvana interns of beaming from the 10 in her I use 1700hz as the XO.
It works for me.
I would hesitate at tryibg this with a 12 or 15 inch driver.
As muds, I cross them to 18's at somewhere in the 200hz region if I recall.

Sure, my '50s era Altec 515B are rated 20-5 kHz, though the GPA Altecs are 'only' rated to 4 kHz. This high a performing 15" aren't cheap though regardless of brand.
Generally speaking, these super high performers are for horn loading with 1200-1600 Hz being the normal max XO point to a mid and/or tweeter horn, so if using another type of tweeter it's often required to use multiples or even make a proper line array to increase tweeter LF power handling.
OK, but the [mid]bass cab still needs at least an octave below the XO point, so still 'talking' a 15" or dual 12" for high efficiency.
What GM said, FaitalPro makes some real nice 15" in this regard as well. I use their 15PR400 and am happy with them. I've crossed them @1khz 4th order and 1.2khz 2nd order. Both applications sound very good.
If you intend to use your subs you could get away with around a 3cuft sealed enclosure. These will reach pretty low but you'll be looking at really pushing them with EQ and the enclosure will want to be 6-7cuft (critically damped). In a sealed enclosure of this size, they are down 3db @35hz in my room.

There is a good choice of drivers at:

I think they are the biggest in the uk.

The TPL 150 does not impress me at all. It does not have the air and clarity of the Faital HF10AK or HF108. these two have detail and beautifully smooth top end!!!!!!!!!
Thanks yes I did and found a canadian company selling them so I ordered the 2 comp tweeters with horns and 2 2515 mids in 12" size as they model in about 1.6 cuft sealed.
I will mount these in separate boxes and try 1 woofer with the tweeter and then add the second and just stack them up or try a mtm style before I put them in one enclosure.
I’ve seen people comment the best horned and non horned tweeter they’re heard are compression drivers period.
An awful lot of this epic thread talks about what you're thinking.
Is it possible to cover the whole spectrum, high spl, low distortion with a 2-way?
Also +1 for the FaitalPro 15PR400, lovely driver.

Pano, that is an interesting observation. Assuming the crossover is well behaved do you think it is related to cone breakup harmonic distortion and a shift in source point between the center of the drivers? Do you think a coaxial like the Altec 604 would exhibit the similar behavior?
Agreed. 15" beams badly by the time it can pass to a 1" CD.

Good questions about CTC distance and coax. From my experience with 12, 15 & 18 inch coax, they do pretty well, although some of those 15 and the 18 had 1.4" compression drivers. Coax often have the problem of the cone waveguide/horn not being deep enough to fully support the low end needed for the low/high crossover point. The coax usually does do voice well. I've enjoyed the Altec and Urei, and some others like Tannoy to a lesser degree.
I have used dozens of different models of pro 2-way speakers with horns. Many modern versions have horns that are wrap around the woofer - one would assume for better CTC distance. And yet I've never heard a 15" woofer and 1" horn that sounds natural on voice. 12, 10 and even 8 inch woofers with a 1" CD almost always sound more natural, especially on spoken voice. With singing, you can get away with a lot.
So yes, maybe it is the CTC distance. I had not thought about that, it just seemed to me like the 15" woofer wasn't sounding right at the top of its range where it crossed to the horn. Good point.
