[QUOTE="sundownz, post: 6512224, member: 549523"] I am not planning an 8" for this line any time soon... but I am planning 10s, 12s, and 15s... also... I do not have an ETA just yet, first prototypes are on the way then testing will be in order for a while to make sure the design suits all of my requirements. Just though I would offer a sneak peak of the 15" model. [IMG]http://www.sundownaudio.com/misc/protos/E_Series_v2/E15.jpg[/IMG] I AM planning to use spring loaded push terminals on production... I don't like the spade connectors. Some T/S Specs measured on the Klippel machine at the factory... I will measure them myself as well once my prototypes arrive.
