Monoprice 8-inch Powered Studio Monitor Speakers (pair) The tweeter is a 1.25" silk dome design with magnetic shielding, which is designed for a flat frequency response and accurate musical reproduction. The woofer is a 8" Kevlar cone with magnetic shielding, rubber surround, and a high-temperature voice coil, for long hours of high volume work. This use of dual amplifiers ensures that each driver has the power it needs without compromising the output of the other driver, ensuring that the audio output remains crisp, clean, loud, and distortion free at all times. Each monitor enclosure includes two separate power amplifiers totaling 120 watts (RMS).A 40 watt amplifier is used to drive the tweeter, while a 80 watt amp drives the woofer. Each speaker is separately powered, is bi-amped with two dedicated amplifiers, and uses both balanced XLR and balanced/unbalanced TRS/TS audio input paths. These speakers are professional quality studio monitors for a flat frequency response for studio recording, mixing, and mastering duties.
