Sony ULT TOWER 9AC vs JBL PartyBox Stage 320

The JBL PartyBox Stage 320 is an optionally battery or A/C-powered speaker that weighs nearly half of the larger, Sony ULT TOWER 9AC. Its frequency response is more balanced, but it doesn't have as much low-end as the Sony. However, it compresses less at max volume, and despite its smaller size, it still gets very loud. Its controls are straightforward and focus on audio playback, while the Sony includes direct controls of the lights. Both include mic and guitar inputs and similar Bluetooth and wired connectivity, although the JBL has a wired line out, which is handy for adding any speaker with a line-in, and the Sony includes Optical input for connecting a TV or projector. On the other hand, if you're into bassy tuning, the Sony is the way to go. Like the JBL, it gets loud and it's quite bassy. That said, you need a power source nearby to use it.
