Bookshelf Monitor Speakers RBS-52

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 musical studio, the RBS-52 was engineered to maintain high fidelity sound quality in a compact enclosure, and all for a compact price.

RBS-52 is designed with 25mm silk dome NEO tweeters to allow 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 provide 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 precisely tuned to 40Hz. This enforced bass reflex, double-ported enclosure reproduces superb low frequency extensions without resonance.
