Designed as a great replacement for most OEM speaker applications, the S Series speaker systems offer great performance at a great price. We even improved our tweeters to make sure that even the most discerning listener is satisfied. This range offers a complete line-up specifically sized for OEM drop-in replacement of 2.75″, 3.5″, 4″, 4″x6″, 5.25″, 6.5″, 6.75″, 4″x10″, 6″x8″ and 6″x9″. We invite you to put our S Series to the test and compare them to speakers priced much higher. Our proprietary 2-layer paper cone features DDC, allowing you to hear smooth and rich bass all the way through the mid-range tones. For the high frequencies, we feature a low profile, pure silk dome tweeter like the type used in expensive home systems–to make sure you get a complete hi-fi experience.
