dbx 100 Boom Box Subharmonic Synthesiser

Rediscover the depth of your music with the dbx 100 Boom Box, a device that regenerates the low-frequency bass often missing in recordings. It meticulously recreates the bottom octave, enhancing the accuracy and power of live bass notes. The Boom Box brings back the solidness and three-dimensionality of bass heard in live performances, allowing you to physically experience the richness of sound.

In the recording process, engineers often limit the depth and excursion of record grooves to fit as much music as possible, which results in the lower frequencies being deliberately cut off. This makes life not all highs—there’s a need for those deep, resonant lows that make music feel complete. The dbx 100 Boom Box addresses this by restoring those essential low frequencies, giving your audio the full spectrum it deserves.

Most recordings provide an accurate account of music’s frequency range down to about 60Hz, but the crucial octave between 25 and 50Hz is often missing or very weak. The dbx 100 Boom Box recreates this lost portion of the audio spectrum by utilising the program material in the region above 60Hz to synthesise signals one octave lower. It then mixes these synthesised signals back into the program, effectively restoring the lost bass frequencies.

The dbx 100 Boom Box features two main controls. The first is a synthesiser control, which acts like a gas pedal, allowing you to set the amount of synthesised low frequencies you want to introduce into your system. The second is a low-frequency boost control, specially contoured to produce a smooth blend of the synthesised notes with the existing music. This ensures that the addition of low frequencies feels natural and enhances the overall listening experience.

Using the dbx 100 Boom Box is straightforward. Insert it into the tape monitor circuit of your receiver or amplifier, and adjust the low-frequency boost control until your ears tell you it’s just right. This process fills in the gaps in the lows that often rob you of the sensation of a live performance. The Boom Box can be enjoyed with almost any component system, making it a versatile addition to your audio setup.

For those with higher-powered systems, the Boom Box can create a completely new dimension of sound. You can turn up the system until the sound becomes a visceral sensation. Huge blasts of air from the pulsing low frequencies can be felt in your chest and stomach, producing a sensation unlike anything you’ve ever experienced from recorded music. The room fills with low-frequency energy, turning you into a resonator and creating a “superreal” audio experience.
