Sonodyne PM 4040 Near Field Monitors Speaker – Pair Overview:

The PM 4040 is a cost-effective solution for high-quality near-field monitoring

The stereo set comprises a pair of monitors one active and the other passive. The cabinet material is MDF and the front baffle has a unique molded shape. The 1-inch silk dome neo-magnet tweeter is nested in an elliptical custom waveguide for a smooth response and wide directivity in the horizontal plane but controlled directivity in the vertical plane. The LF is a 4 glass fiber cone woofer. The system is powered by a 2-channel class D amplifier.

The resulting sound is detailed with a wide sweet spot and frequency response at appreciable loudness.

There are both unbalanced and balanced inputs and also a headphone output. A master level controls other overall volumes of the pair.
