With the prevalence of computer based music editing solutions, there is a greater need than ever for a great sounding set of small, shielded speakers, such as these 3-inch Powered Portable Monitor Speakers from Monoprice!

These monitor speakers are designed to produce a flat frequency response, which makes them perfect for use by audio professionals or anyone else looking for true and accurate audio reproduction. Powered by a built-in audio amplifier, these monitors can be used anywhere AC power is present, while magnetic shielding ensures that they will not interfere with computer monitors or television displays.

The master speaker contains the controls, connections, and built-in 30 watt amplifier (15 watts/channel). It connects to an audio source using L/R stereo RCA jacks. A 3.5mm jack on the front allows you to connect a pair of headphones, which disables the speaker output. Another 3.5mm jack on the front allows connection of an auxiliary audio source. A Bass Boost switch on the back of the speaker increases low-frequencies by 3dB, for improved volume and greater bass presence. The second speaker connects to the first using standard speaker wire.

The tweeter is a 1" silk cone design with magnetic shielding and internal damping. The 3" paper cone woofer is coated in polypropylene to produce a flexible, but incredibly strong, speaker that is capable of both accurate reproduction and loud volume levels. The woofer is magnetically shielded and uses a high-temperature voice coil, so it won't fail under heavy use. The drivers are covered with a protective grill, making them easier to transport and better for use in rough environments.
