Title: Sunn 12" SPL-91212 Pro Series
Post by: bigobassman on March 30, 2020, 12:58:58 am

I may have asked this before, but if I did, I can't locate the thread.  In any event, I've had this speaker for several years.  It looks in like new condition with a huge magnet.  I've looked and looked for information on it and don't find anything.  I have a possible use for it, but would like to know the performance details/specs first.  Your help appreciated,   :-)

I have some data for a SPL 912E and a SPK 912R. Those are naked Speakers. Nothing for an SPL 91212. Is it a naked speaker or a cabinet ?

Thanks guys.  Ever since I posted this thread back in March, I could never hit reply for the thread and it work.  Wasn't ignoring anyone, just some glitch that I've never had before.  Periodically, I would try reply for this thread and until tonight, it never would work properly for me.  Oh well!   :-)
