Default modern version of church monitor

Someone please direct me to a driver/enclosure that would have a similar sound to this EV CM12-2. I sits in front of me on stage and I like the sound. If I'm reading the specs correctly is has a SPL of 97dB/W/M.

Eyeballing the frequency response, the 12" Fane triple-cone might do what you're after.

It is a coax with a dome tweeter from what I see. I don't know of anyone major league who makes a monitor that way anymore!

There are coaxial monitors made but as far as I know they almost all use compression drivers. With the perhaps lone exception of the Martin Le100. But it is not cheap!

With good reason. Dome tweeters have very limited output. Compression drivers, by nature, can have bigger voice coils and more radiating area - more power handling and more efficiency = more output.

The current Martin LE100 has a compression driver.

That tweeter was used in lots of EV products. S100 & 200 "Entertainers" as well as most of the Sentry product line. I have several in one of my listening systems that I just cleaned-out, re-diaphragmed and ferrofluid and they now sound wonderful again. Any of the EVM or DL-series 12" woofers work great with them so it wouldn't be too difficult a project to build your own and mount the tweeter in the same way using a bridge (instead of finding the special co-ax type woofer.)

98dB but you will need to develop your own XO.

B&C 12FCX76 12" Professional Coaxial Speaker 80 x 80 8 Ohm

Less pricey stamped steel frame 97dB. Add $30 compression driver from PRV etc.

Eminence Beta-12CX 12" Coaxial Driver

Couple questions.
1. Why are PA speakers bad for home hi-fi? If I like the sound I'm hearing on-stage, why wouldn't I like it at home?
2. If the B&C 12FCX76 has a FR from 47 to 18,000 Hz, why would I need a XO?

1 - They don't, necessarily. The frequency response of the EV monitor isn't what I'd call HiFi, though. PA components can work well for home HiFi.
2 - It's a coaxial. Two drivers in one.

This is my opinion. PA speakers are designed for efficiency and ruggedness. Sound quality is typically not refined sounding like good monitors or Hifi gear. There are exceptions of course. In general, PA sounds a bit harsh and gritty. Much of that can be blamed on compression drivers which don’t do well at lower frequencies where they have distortion and a spitting sound. They really should be operated at 2.5k and above but are called to go down to 1.5k or lower.

The coaxials from any pro audio company is just the drivers and they are capable of the range specified but need a XO to accomplish the integration or use active XO with DSP and multiple amps.

So, merely because the tweeter is situated in the center of the woofer, that doesn't mean it's functional; it requires a cross-over circuit to operate, correct? Wow, today I learned!
I suppose that's why a coaxial isn't technically a full-range driver?
