# REDCATT

> REDCATT Technology CO., LTD. designs and manufactures professional loudspeaker drivers and audio transducers — subwoofers, woofers, midranges, compression drivers, tweeters and coaxial point sources — for professional audio, OEM and ODM applications. Engineering team in Europe, the US, Australia and China; manufacturing in Dongguan, Guangdong.

Full Thiele-Small parameters, physical dimensions, materials and power handling are published for every product, both on the product pages and as JSON at https://www.redcatt.net/api/v1/products.

Ordering codes (e.g. DR-21-002-4R-B2-C0001) are the unique identifier — model names such as 21NPW are shared across impedance and variant options.
