Thanks to the success of the SD-2 8" model I started developing the SD-3 line; this will replace all SD-2 models in 8/10/12" sizes (there is no 15 in this series).
The SD-3 motor and coil design will become under-hung like the 8" model on the bigger 10 and 12" models -- I am also further optimizing the parameters of all models for sealed enclosures... even the 8" model will be tweaked a bit more
So this thread will be used to update about this line as parts are finished. I am starting out with the 10" cone and surround tooling then will make those prototypes first. The tooling process has started for that so hope to have a picture of a prototype within ~30 days or so. Assuming all is good I'll do the new 8" and 12" models next.
As far as release date... by the time prototype is done and production is done probably October or so.
IMO they are going to be pretty incredible... SQ fans have been going nuts over the SD-2 8s and with the SD-3 the 10s and 12s will get a huge SQ boost.
