Monolith MM-3 50W desktop speakers

The Monolith MM-3 is a compact powered speaker pair delivering 50 watts of combined Class D amplification. A 3/4-inch silk dome tweeter and a 3-inch polypropylene woofer are driven by a DSP-controlled bi-amplification system. A rear slotted bass port extends low-frequency response down to 55 Hz for a spacious soundstage.

Ideal for near-field listening on a desk

These speakers suit home offices and bedrooms where wired RCA or 3.5 mm connections and aptX Bluetooth streaming are convenient. A front-panel headphone jack allows instant private listening. Buyers needing higher output for larger rooms or additional digital inputs such as optical or USB should consider other options.

Front headphone jack and aptX Bluetooth

The built-in front headphone jack lets users switch between speakers and headphones without reaching behind the desk. Qualcomm aptX codec support improves wireless audio quality over standard Bluetooth when paired with compatible source devices. RCA and 3.5 mm analogue inputs provide flexible wired connectivity for laptops, tablets or other gear.
