Sony ULT TOWER 9AC vs JBL PartyBox 1000

The Sony ULT TOWER 9AC and JBL PartyBox 1000 have different strengths. While both are large and loud speakers with comprehensive apps that include EQ, the Sony plays back audio in stereo, whereas the JBL downmixes to mono unless you buy a second identical speaker. The Sony also weighs less and is easier to move. Besides similar Bluetooth and mic inputs in common, the Sony includes an Optical port, while the JBL uses RCA. The Sony sounds notably bassier by default, while the JBL's frequency response is more balanced out of the box, and it compresses less at full volume. Other differences are more niche, such as a DJ effects pad on the JBL.
