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.
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.
