Radian, beryllium drivers and front loaded horns

[bonzo75]

Hi what are the upper frequency drivers people are using here on top of front loaded VOTT type bass cabinets? I am thinking of a Radian with Altec 817 type cabinet.

Also, anyone using Radian or any other beryllium driver here?

I've got a pair of Radian 1" 475PB and used the 2" 850PB previously. They both sound very smooth through the midrange/treble.

Not heard any of the Be models.

Thanks, what is your horn configuration, and what was it with the 850

Cooky on here has experience of these IIRC.

The 475 are in a Faital Pro LTH102 and the 850 with a 400Hz Stereolab Tractrix.

And the rest of the speaker? Bass and tweeter (if any)?

I used the 850 in a 2.5 way, with a bass driver (Volt Bm251. 3) and a fountek ribbon coming in from 8kHz IIRC. Long since gone.

The 475 was used in a simple 2-way with a Supravox 285GMF, crossing over around 1600Hz but its all packed up in the cupboard until the summer.
