Sonodyne SM 300 L,R - 3 Way Active Reference Monitor


OVERVIEW

During summer 2010 we set ourselves a challenging task - that of designing a high quality active loudspeaker that would combine the detailing of the award winning SM 100Ak with the dynamics and bandwidth of the SM 200Ak. Additionally, the size would have to be very compact since the target user would place it on a console or desktop. Many design debates, prototypes, and user reviews later, we are delighted to present the SM 300, our first 3 way tri-amplified reference monitor.

The key features in this new monitor are:

  • A compact cabinet which has double MDF top, bottom, front and rear; and aluminum extruded sides. Unique, and exceptionally rigid.
  • The HF and MF transducers are housed in a separate Aluminum die-cast plate, designed for controlled dispersion and linearity
  • 3 AB Class amplifiers rated at: 150, 75, 75 watt that drive the 8" kevlar LF, 4" kevlar MF, and 1" silk dome tweeter respectively
  • 2 shelving EQs for LF and HF, 1 bell EQ for MF, 2 Bass Roll Offs at 80, 100 Hz to compensate for room modes and for optimizing off axis response
