So this appeared on my Facebook feed: 


I am very curious to see what B&C will come up with. They have some catching up to do.

Is there someone that already can tell a little more about these?

Cheers

JBL and Eminence have ring radiators too now. The BLS patent expired.

Had a play with one today.  Very smooth sound.  Maybe too smooth for Rock'n'Roll but I'm sure some people will like it.

Seems like FBT is using this driver in their new MYRA 214L line array cabinet.

Oh and I saw this pic on a FB-page called Swampsound:

there's no way to put all that power at through that size throat over that bandwidth without it distorting.

Can say the same about BMS too. There are plots available for those who ask and you can bet it’s on the VoiceCoil / AudioXpress review list

I would say the same about BMS drivers. reviews typically measure distortion at 2.83V. increase the power by 20dB and you will get a very different distortion plot and realise that at high powers it is throat geometry that dominates distortion, not how expensive your comression driver is.

EDIT: to be fair, throat distortion is mainly second harmonic and less objectionable than higher order harmonics and inter-modulation distortion produced by compression drivers. second order harmonic distortion is so normal that people perceive that as what loud noises should sound like.
