These specially designed interconnect cable types connect your preamplifier or home theater receiver to a powered subwoofer. While a subwoofer only produces the deepest audio frequencies, it can have an important influence on the overall musical or soundtrack presentation right up through the midrange. It is not just about bass response; it is about achieving a real life aural experience. Have a question? Connect with our Audio Gurus at 800-FATWYRE or 215-862-4870 or Send email or use Contact form.
