Test Bench: The UF 295 CBS Ultra-Thin 10” Subwoofer from Neotera

Another exciting driver from Neotera, the UF 295 CBS is a new ultra-thin 10" subwoofer primarily intended for high-quality applications in home audio or automotive systems. The UF 295 CBS impresses immediately with its single piece black anodized concave cone assembly suspended by two large rubber surrounds, one on each side, not using a spider for compliance. The cone is driven at its perimeter by a large aluminum voice coil and a unique motor structure of 72 neodymium bar magnets, covered by no less than 10 international patents. This article was originally published in Voice Coil, April 2024.

Recently, Dinaburg Technology, based in Dallas, TX, was issued their first US patent for an electro-dynamic loudspeaker with an integrated coaxial passive ring radiator. Mikhail Dinaburg, noted physicist and the patent inventor, uncovered some missing elements in previous coax and passive radiator work and set out to prove it. Dinaburg’s patent discloses techniques for higher performance sound reproduction, enabling lower distortion, extended frequency range, higher efficiency, and improved speech intelligibility. The invention has wide applications and scales from a earphone driver to near-field studio monitors, ceiling speakers, under couch subwoofers to the largest concert subwoofers.
