The black version of the EGG150 Monitoring System from Munro Sonic features a pair of analog EGG speakers with an amplifier control unit. Each speaker has a rigid and resonant-neutral curved egg-like monocoque shell enclosure that minimizes diffraction, standing waves, and resonant effects that can distort and smear sound. The speakers feature a 150mm LF driver and a 25mm HF tweeter. Each EGG speaker is connected to the amplifier using a 9.8' (3m) speakON cable (included).


The dual-input amplifier control unit features a Class-A headphone amp, two main balanced XLR inputs, and two unbalanced RCA phono connectors for adding an external CD or media player for reference listening. The unit also features volume controls for the main input channel as well as the Aux input, along with a source-selection switch for comparing the two independent inputs. The unit also features LF and HF trim pots for each channel to tweak the sound as per your requirement. The mid-band equalizer control on the front panel emulates the mid-range response of both HiFi and NS10-type speakers. All electronics are housed in the amp itself.


Rubber nest bases are included to facilitate exact alignment of the speakers in any operational situation. Each nest features a contoured surface, allowing axis tilt in forward or backward directions without obstructing the base port or cable entry.
