Compact Powered Speakers with AMT Ribbon Tweeter

The Monolith MM-5R is a pair of powered multimedia speakers built for desktop and near-field listening. Each enclosure houses a 100-watt Class AB bi-amplification system driving a 5.25in polypropylene woofer and an AMT ribbon tweeter. A slotted rear bass port extends low-frequency response down to 42Hz for punchy bass from a small footprint.

Ideal for Desktop Audio; Not for Large Rooms

These speakers suit home offices, bedrooms and compact workstations where high-resolution sound and multiple wired inputs are needed. Buyers who need wireless multi-room streaming, voice-assistant integration or room-filling output for a living-room setup should look at other solutions.

100-Watt Class AB Bi-Amplification per Speaker

The defining specification is 100 watts per channel of Class AB bi-amplification, which directly determines the system's dynamic headroom and ability to drive the AMT ribbon tweeter and 5.25in woofer to reference levels in near-field use.
