About: Sundown Audio E-Series v.4 10"
This design features a newly tooled, significantly stronger frame meant to resemble the cast frame on the SA v.2 and U series models.The under-spider venting has been upgraded to one of our tooled vent rings to enhance long-term power handling. And, much like the very last of the v.3 series, the motor is fully bolted. Otherwise it is largely the same as the outgoing v.3 and is priced identically.
