Studio > SLF Series

Good quality audio reproduction hinges on the quality of audio production. Sonodyne, India's premier audio design and manufacturing house of 30 years, understand this. To allow for high-grade production values in audio recording and broadcast we present the new SM active studio monitors.

These monitors were created with the utmost attention to detail. It features high-grade components throughout. These are the key elements of the SM series of active studio monitoring loudspeakers.

Monolithic aluminum die cast cabinets: At Sonodyne, we have been studying in detail the effect of cabinet vibration. Confident that this has a significant colouration, we have designed the SM enclosure to be exceptionally rigid. The entire cabinet of SM 50 and 100 is a 6 mm thick monolithic aluminium die cast. For SM 200, the front baffle is aluminum, and the sides and rear, 15 mm MDF. Additionally, The interior walls are coated with a specially formulated deadening compound to prevent ringing.

• Mechanical precision: All sides are anti parallel that greatly reduces formation of standing waves. The inclined baffle also contributes towards horizontal time alignment. Additionally all corners are rounded, and all controls, well recessed to minimize edge diffraction The twin bass ports are flared at both ends to minimize turbulence. The vent area has been optimized to prevent power compression at loud levels.

• Kevlar woofers in metal die cast chassis: The woofer for each monitor has been designed with 2 objectives in mind : As a bass unit, it should provide fast, tight and low distortion bass from the modest sized enclosure, and, as a low mid unit it should yield a smooth frequency response, good transient response and minimum cone break up. Kevlar was the obvious choice of material. The bass performance was achieved by optimizing the T/S parameters to suit the enclosure volume and by equipping it with a powerful motor and long throw voice coil. The mid performance was achieved by optimizing the cone geometry and the dust cup.

• Integral waveguides: The 26mm dome tweeter, for the 100 A, has a wide dispersion at high frequencies made possible by the integral wave-guide. In conjunction with the waveguide, the dome produces smooth response out to 22 KHz. A rear chamber design pushes the tweeter resonance peak to below 1kHz allowing for a low crossover frequency thereby minimizing phase errors due to horizontal time alignment. The SM 200, with a new waveguide design features excellent off axis response, that allows it to be placed farther from the console.

• Advanced Electronic Design: The LF and HF units are biamped; i.e., powered internally and separated via an active crossover. The internal amplifier and crossover are dimensioned to the respective drive units. This provides for an optimum utilization of amplifier power. The amplifier features very low THD and IMD and exhaustive protection measure to ensure safety and reliability. Use of a toroidal transformer, selection of low noise op amps, minimal signal wiring and careful PCB layout contribute to a high S/N ratio which creates a very low self generated noise level. The crossover is a 4th order design. The steep attenuation of out of band frequency components creates minimum overlap resulting in smooth off axis response, as is evident from the polar plots. User operated controls include a gain control and 4 bass tilt and treble tilt DIP switches for workstation boundary compensation. Also included is a master volume control and power switch. Input is via fully balanced XLR or TRS sockets.
The resulting sound obtained is objectively represented in the on axis frequency response, polar plots, 2nd & 3rd harmonic distortion plots and the cumulative spectral decay (waterfall) plots for each model .The subjective effect is a neutral, transparent sound field with a wide sweet spot and precise imaging.
