Does anyone have any info on this driver? I've got one in a box someone built years ago, but the box is too small and it sounds boomy. Any designs out there that would work with this driver?Josh

Whereas that driver was made in the day LONG before T-S...I doubt there are any parameters that are "official"...you could always measure it yourself with the appropriate gear...check out parts express...they have a T-S measurment gizmo they are offering.Steve

SO are there any box designs out there that will work with this guy? I assume that back in the days when they built these they did everything by ear? or how exactly did they get everything tuned? Also, what kind of glue should I use to glue the cone back together? my finger whent through one side when I tried to lift the heavy pig.
