They believe that great people make up a great company. So they employ the skills and expertise of some of the best people, manufacturer's representatives and distributors in the industry. Whether your needs are to talk with a local representative or someone on their engineering team halfway around the world, you can be confident that DB Unlimited has the solution to get the job done.


How are they different?

DB Unlimited is the world leading audio solutions provider committed to maximizing customer designs and helping solve engineering design challenges. Their 40 years of industry experience has resulted in the most comprehensive offering of acoustic components in the industry. They offer a vast array of innovative technical resources and as part of their dedication to industry leading customer service, they partner with the best local representatives and distributors, ensuring their customers of truly UNLIMITED possibilities, regardless if they are down the street or across the globe.


What are their most popular products?

DB Unlimited’s 67 Series Waterproof Speakers are specifically designed and manufactured to provide IP67 protection. Not only will they survive and operate normally after being exposed to splashes, spills and sprays, DB’s 67 Series will keep dust, water and pretty much anything else Nature can come up with, out of your product.

DB Unlimited understands it isn’t just about keeping sand and surf out of a portable speaker during a day of fun in the sun.

  • It’s about first-responders having clear communications regardless of the environment when they answer the call.
  • It’s about lifesaving medical equipment providing clear feedback and alarms without wipe-down procedures damaging the speaker or letting liquid inside the device.
  • It’s about heavy equipment operators being able to count on their warning devices working after being sprayed down and that mud and water haven’t damaged internal electronics.

The 67 Series’ starting line-up includes 4Ω and 8Ω speakers, ranging from 18mm to 44mm. They come in round, rectangle and oval frames; with and without mounting flanges. Supporting frequencies as low as 300Hz, DB Unlimited’s 67 Series speakers are suitable for virtually every audio application requiring water resistance.


Besides the 67 Series, DB Unlimited also sells indicators, transducers, piezo benders, speakers and microphones.


What are some of the applications for their products?


Whether you are working on a handheld medical device that is power conscious or a piece of emergency room equipment that needs an alarm to hit a certain output level, DB Unlimited is here to offer their superior expertise and design support to make your development journey easier.



Whether your product finds itself on the manufacturing floor, on a sea port dock, or simply out in the elements of weather, harsh environments are brutal on electronic components. DB Unlimited understands this. They design and manufacture their products, knowing that they are not always going to be performing in their clean, quiet anechoic sound chamber, but rather are more likely to be called upon to perform in the harshest industrial environment.


Whether it is an automobile, a recreational vehicle, or a mass transit system, applications in the transportation industry have special requirements for the electronic components they use. Special certifications for the factories in which these electronic components are manufactured, the environments in which the components are expected to perform, and how even the simplest component is somehow related to the safety of the end user are just a few reasons why many component manufactures avoid supporting transportation customers. At DB Unlimited, not only do they not avoid such customers, they focus on such customers. Several of their manufacturing facilities are TS16949 certified.



It seems like the moment you purchase the "latest" consumer device, someone comes out with a newer model with more or better features. This is because the consumer industry is constantly pushing the limits of technology in order to get an edge over the competition. DB Unlimited understands this and is continually devoted to supporting the "next" technology for their customers in the consumer industry.

Smaller, louder, more power efficient, etc, the technology team at DB Unlimited is constantly making what was once impossible, possible. They lead the industry by introducing audio products that can help define your next generation product, but they can also tackle any design challenge by creating an audio device from scratch that makes completing your next generation product a reality.

They have a product capacity of over 57 million per month, enabling them to support the largest consumer customer. Yet, they don't hold back their engineering resources from the small startup, knowing too well that all great companies have humble beginnings.

Fire, Safety and Security

At DB Unlimited, they are honored to be involved with many of the devices used by those who keep them and their families safe. Just the industry classification of "Fire, Safety and Security" in and of itself expresses the high level of expectations held for the components used in such devices. However, it is in such extreme application where the technology and quality found at the core of DB Unlimited is proven superior.
