Got the response from DLS and here it is:

Hi Sam,


Thank you for your email,

We expect first shipment of UP-4 to arrive first week of March, I will then test the x-max.

Fs raw (not broken in) 94Hz
Fs broken in 85Hz
Voice coil diameter 30mm

I good guess of the x-max would be 3 or 4mm one way.



Best regards

Peter Flodkvist/DLS
