JDK Audio (Arsenal by API)

About Manufacturer

JDK Audio is an entirely new brand developed and engineered by API, a company that has been around since the late 1960's. Originally called Arsenal Audio, they have permanently changed the name of this fabulous new range to JDK. And, while API had a stellar range of excellent audio products that are benchmarks of the recording world, we decided to embark on a product line that would allow our engineering team to develop some new ideas that have been floating around our engineering table for years. After all- we're a Technology company - its what drives us - its what inspires us. And some of the new technology available to us is pretty cool stuff - it just doesn't fit anywhere in the API product mix. So JDK audio was born out of desire to expand the creative options we have available at API - no boundaries - no restrictions
