Default Good 2" compression drivers?

Hello all, I'm looking for a good 2 inch compression driver to go into some new cabinets I'm building. I favor jbl's 244* series, but they are so heavy it's not difficult to snap off the neck of a horn without a support structure. Any thoughts? Thanks!

What's your budget?

Here's a neo mag one from Selenium.

Almost all compression drivers (at least serious 2" units) will require a support bracket, including the Selenium Neo unit (at 7.5 lbs). This is a good bit of weight to hang on to an extended horn. In the old days, most horns were made from cast metals, but today, almost all are fiberglass or ABS. Use a bracket!!

Thanks Cal and Ron, we had looked at that selenium driver, have you heard it?
After looking around at 2 inchers, it does appear that any driver worth it's weight is gonna have some mass to it. It is going to be mounted to a 110 degree horn in a line array box so the neck won't be too long but it's still a lot of force to be hanging there.
Budget wise, considering what jbl gets for a 2446, probably anything less than one of those. Around $200 per would be a nice max though. Thanks!

Radian Audio is another possibility. I have used their diaphragms (both 1" and 2") in JBL and TAD drivers and they sound very good.

Just another option. Good luck

I'm not familiar with these drivers but I have heard a few titanium diaphragms. I really didn't like their sound compared to the aluminium diaphragms. Maybe someone here has more experience with these drivers.

I like the B&C 1" exit with the mylar diaphragm, but I haven't heard any of their larger drivers.

You might also look at BMS drivers - they have one that's more of a dedicated midrange as opposed to trying to cover the midrange and high frequencies. They use mylar ring diaphragms.

Though I don't have any personal experience working with 2" compression drivers, I've heard good things about the BMS neo coaxial unit (the 4594ND). Though the measurements in VoiceCoil magazine are pretty simplistic, the Beyma CP-750Nd was measured and the results looked just like the published spec.

It also like B&C and Beyma are on the top of people's lists these days with respect to state-of-the-art compression drivers.
