The newly developed RBS-52 passive studio monitor from Earthquake Sound is designed to be as versatile as it is technical and beautiful. Perfect for a home theater set up or a music studio, the RBS-52 was engineered to maintain high-fidelity sound quality in a compact enclosure, and all for an afordable price.

Earthquake Sound has always understood the importance and relationship of sound quality and enjoyment of the user’s experience. That is why Earthquake has designed the RBS-52 with 25mm silk dome NEO tweeters to allow a faster response, as well as a better frequency range. This feature, coupled with the 5.25” low-mass rigid carbon fiber midbass driver with patented PistonMax™ technology provides you with 25% more accurate sound pressure levels as well as lower harmonic distortion.

The finely finished matte-black cabinet is designed and engineered with the same care and attention to detail as every component of the speaker and holds an equally important part. Not only was the speaker designed with an aesthetic finish to fit in with any decor, but the cabinet is precisely tuned to 40Hz. This enforced bass reflex, double-ported enclosure reproduces superb low-frequency extensions without resonance. This feature, combined with the speaker’s compact size, allows the user to place the speaker virtually wherever they like and still be able to receive a full range of sound. A self-centering, removable magnetic grille literally and figuratively seals the deal on this high-end performing, budget-friendly speaker.
