2 x 35 Class D amplifiers give you a combined 240 watts of amazing peak power Two speaker drivers: a 3⁄4 inch tweeter and a 4 inch woofer. Connect two speakers wirelessly or using cables, to use the stereo setting One speaker serves as the left channel – and the other one serves as the right channel. With the stereo setup you get a real reproduction of three-dimensional sound; sound that pans from side to side, goes up and down, and moves back and forth. A dedicated DSP algorithm, taking its foundation from the stereo experience, creates an ambient sound from one single speaker – and that sound has the spacious characteristics of a stereo setup. You can use the ambient setting whether you have 1, 3 or even 4 speakers in your setup.
