This is a pair of Pyle active monitor speakers that feature Hi-Fi Full Range Stereo Sound Reproduction and Pro Audio studio performance. They are in excellent brand-new condition. They are designed for high quality performance in your home studio setup or desktop studio system. The right speaker is active with the built in 2-Channel Digital Audio Amplifier and rear panel Control Center. The power output is 300 Watts Max and 150 Watts RMS. The bass response is excellent for these size speaker cabinets that are 10.6" high, 6.7” wide and 7.5” deep. These speakers really kick with a 5.25" woofer and a 1.0” aluminum dome tweeter with an impedance of 4-8 Ohms. They are compatible with all computers and digital audio workstations. When you’re ready to listen to some professional mixes, this system is set up and ready. Email me if you have any questions.
