8″ Subwoofer
Type Number:
Features:
 830667
The SLS line combines high quality performance with an 
affordable design. These transducers are ideal for use in systems 
with high power handling requirements, and are logically 
combined with the SDS line. 
Driver Highlights: Coated paper cone, 39 mm voice coil, AL 
shorting ring in magnet system.
