Compact Yet Powerful In order to deliver maximum performance from a compact enclosure, Sonica has four separate amplifiers that are set up in a 2.1 stereo configuration. Two 15-watt amplifiers are connected in a bridged mode to drive the 3.5" bass woofer and two 3” bass radiators with a combined power output of 30-watts. Two additional amplifiers, 10-watts each, power a stereo pair of 2.5" wideband drivers. Utilizing a 2.1 stereo configuration is a time-tested approach that allows for the best possible performance. Amazingly Strong Bass The bass radiators utilized in Sonica are unique for a product in this price category and serve to further improve performance. The two complementary bass radiators are located on each side of the enclosure opposite each other. Not only do they enhance the bass response, they also cancel unwanted vibrations in the speaker enclosure. This ensures that Sonica remains stationary without rattling and shaking when music is played at very high volumes. Expertly Tuned Design Audio systems require very careful design and optimization in order to take full advantage of their components in the best way possible, and OPPO’s engineering team meticulously considered all aspects of audio reproduction and customers’ sound preferences in order to make Sonica a great sounding, reliable, and easy to use companion for music lovers. The speaker drivers, amplifiers and chassis are expertly tuned for a deep, pure, and engaging sound. One of the most challenging problems for optimizing speaker sound is speaker placement. Rooms have a very significant influence on a speaker’s sound and in some cases the room environment can have a negative impact on the sound from the speaker. Sonica features built-in presets for optimizing the sound for different room sizes, speaker locations, and listening preferences. Optimal Ampilifer-Driver Matching The amplifiers in Sonica have been specially designed for each of the speaker drivers, and all of the drivers are optimally integrated using a Digital Signal Processor (DSP) and are individually driven via electronic crossovers that are carefully tuned to achieve the best sound balance. Custom Drivers for Performance Sonica uses very high performance drivers. The 3.5” bass woofer features a heavy magnet system and large linear displacement capabilities. The bass radiators utilize linear suspension with optimized axial stability to avoid distortion at high volume levels, and the 2.5” wideband drivers use a high energy Neodymium magnet system with copper shorting caps that are normally found only in high-end speakers. This dramatically minimizes distortion in the critical vocal range and ensures clarity and natural sound reproduction for pleasant and non-fatiguing long term listening. Structural Strength Structurally, Sonica is molded from tough, glass-filled ABS polymer compounds, and the enclosure’s shape was purposefully designed with curved surfaces for a wider sound field. Multiple internal reinforcement ribs provide maximum stability. The power supply and amplifiers are installed on a solid metal baseplate that facilitates heat dissipation and results in cooler, more reliable long term operation of the active components in the speaker. These internal structural support elements give Sonica a very stable fundation for producing vibrant sound free of distortion.
