Description:
The Superior Dynamic Sounds (SDS) Series provides the smallest
but highest-quality subwoofers in the industry today. Leveraging the
best in Danish craftsmanship, but manufactured to be very
affordable, these audio transducers are ideal for use in small
surround sound systems, but can also be used in a wide variety of
end user products and applications. The speakers in this line are
combinable with subwoofers in the SLS line--for example, these two
products work extremely well together in home theater solutions.
