Description of 44L7S122: The Solo-Baric revolves around KICKER's most advanced cone design, the injection-molded SoloKon. The 360-degree, constant-contact back bracing adheres directly to every contour of the square cone, adding targeted strength, reliable performance and accurate response for the super-clean bass you've been looking for. Description of Go Party D4: The Go Party D4 is a very large portable Bluetooth speaker with really cool LED lights, and 2 passive radiator woofers that play deep bass frequencies. This speaker plays extremely loud and has the ability to wirelessly pair 2 of them together. This has a very long battery life along with battery status indicator LED's. You can use the speaker to play back music on a USB drive or use the aux input to connect any other audio sources such as a computer or laptop. What sets this speaker apart from the competition is that it is way larger, way louder, and has way more bass than most portable speakers. If you compare this speaker to normal sized ones you can see that this is almost 10x bigger. We also utilized a boombox style design with a carry handle making it really portable.
