JammyPacks pump LOUD. We use only the highest-quality, water-resistant, silver stamped magnetic, open source, mini-speakers; boosting 5W of stereo-amplified beats per speaker. Engaging in the highest qualified range; volume with quality. Why does your JammyPack sound better than all the other portable speakers on the market? It's all in our uniquely designed, single-volume, balsa wood box construction. Allowing for the perfect balance of volume depth X speaker diameter ratio. Coupled with our 8W internal driver that has been "balance engineered" to distribute a variable range of power to each speaker, preventing blowouts and distortion.
