Tons of horsepower, great looks, and flexible connectivity options make these speakers the definitive desktop speaker system. Featuring a separate 50-watt RMS amplifier for each of the four drivers, these speakers produce deep and solid bass, without the need for a separate subwoofer, plus clear, clean, and articulate mids and highs. The USB input option makes them the perfect audio companion for a desktop computer gaming system. The dual RCA line inputs allow you to connect to up to two line level audio devices and the Bluetooth® radio allows for easy streaming from your mobile device. An infrared remote control is included so you can adjust the volume and switch inputs without leaving the comfort of your couch. Sound Quality Life is too short for speakers that don't sound great! We believe that the whole point of listening to music is to hear it as the artist intended. Our engineers and audio experts have spent countless hours listening to and comparing various speakers and headphones until we were satisfied we had found models that fit our demanding standards. Connectivity We want you to use these amazing speakers with everything, so we packed them with connectivity options. Use a USB cable to connect to your Windows® or Mac® PC or use the Bluetooth® feature to wirelessly stream music from your phone. The dual RCA line inputs feature a high-level input for connecting to line level audio components, such as CD and DVD players, and a low-level input for connecting to the headphone output of an mp3 player or other mobile device. Power Oh yeah, baby! You say you want power, well these speakers have power and then some. Each of the four drivers is powered by a separate 50-watt RMS amplifier, for a total of 200 watts RMS! Ordinary powered speakers, with only a single amp per channel, suffer when one driver wants more than its share of power, causing the other to be underpowered. This can cause distortion or even speaker damage. By using a separate amp for each driver, we ensure that each tweeter and each woofer gets all the power it needs.
