I’ve had the SVS micro 3000 matched up with the CW4… So cool to be able to stream music or play CDs and have access, hands on, the Subwoofer! I just cannot imagine having a Subwoofer that is not adjustable like the SVS micro 3000, and right from my iPhone! Active adjustments to the types of music and all the variables that you can possibly run into filling in more or less on the bottom, as necessary to your particular ear! Not the ear of the manufacturer.
