Hi All,

Any suggestions for good alternatives to the M222-8  12" drivers in the JBL MS112?

I have 2 with blown drivers, compression drivers are fine.

Thanks!

M222-8 T/s parameters (thanks to _djk_ for the link! http://www.jblproservice.com/pdf/Thiele%20Small%20Parameters/Theile%20Parameters.pdf)

FS   QTS   QMS  QES   VAS  EFF    PE    XMAX   RE   LE     SD     BL    MMS FLUX
71   0.48  3.6    0.55   41.9 2.62   300  6.35    4.2   0.43 0.053 12.8 48     1

There's a starting point. Finding drivers with near to these T/s parameters won't be easy, but work out the box and port dimensions (doesn't need to be precise, just a ballpark figure), model it, model alternative candidates and compare plots.

Beyma 12MCS500 may be a good option. Fairly similar on several counts.
