The RPB21 by Rockville is the result of many months of engineering. We had to go through 3 prototypes until the product manager approved the sound. The end result is a Bluetooth speaker with many playback options that is the loudest in its class!

As we always do, we had our team compare this model with many different speakers from famous brand names that sell for way more money, and our RPB21 went louder and sounded better than the famous branded speakers. Our model also had a longer-lasting battery and more listening options.

Sleek and Classy Design!
The design we made for the RPB21 is sleek and classy. The intention when making this design was to create a speaker that will look good in a beautiful kitchen, bedroom, or living room. This speaker has a black powder coated finish with pewter accents on the top and sides. We finished off the design with a gun-metal colored grill that makes this piece timeless.

True Stereo Sound!
This speaker has 2 drivers built-in along with stereo sound processing. The sound quality is extremely crisp!

Listen At Home Or On-The-Go!
The RPB21 is loud enough for your bedroom or living room, yet it is small enough to take with you to your next get-together.

Extreme Power!
The Rockville RPB21 has an amazing 30 watts of power! What I love most about this is that even when you crank up the volume to 100 % you do not hear any distortion at all. This is a feature we put into all of our Bluetooth speakers. We added a limiter circuit that will not allow you to distort the speaker.

This speaker is driven by two built-in 2 inch drivers. Each driver has a ferrite magnet and 133-gram horns. They also have rubber surrounds that eliminate unwanted distortion and increase the sound quality. The drivers we use are hands-down better than anything else on the market!

These have true stereo sound (2 channels), giving you the best possible listening experience.

Long-Lasting Battery
The battery lasts for 10 hours with the music playing at 70% volume. If the volume is lower, it will last even longer! This has a 3.7 Volt 2000 mAH battery. We use only the best quality batteries in our speakers.

Aux/SD/USB/Bluetooth/FM Radio Playback
The RPB21 has tons of listening options. This is more than just a Bluetooth speaker! It also plays audio stored on a USB or SD (up to 32GB). You can plug any audio device into the 3.5MM aux input. This even has a built-in FM radio. The Bluetooth range is around 32 feet. The Bluetooth needs to be paired the first time you use it, and then after that it will auto-pair to your phone when you turn the speaker on. Our Bluetooth quick-connect technology pairs in 5 seconds!

Anti-Vibration Feet
This speaker goes so loud that we needed to add rubber anti-vibration feet to stop the speaker from shaking and vibrating when playing at max volume levels!

Top Build Quality
The enclosure is made of top quality ABS molded plastic and metal. It is built extremely well and uses top of the line components.

Built-in Speakerphone Integration
Another cool thing about our feature is the built-in microphone. If your phone rings, you can answer the call and talk hands-free using this as a Bluetooth speakerphone.
