Sony ULT TOWER 9AC vs JBL PartyBox 720

The Sony ULT TOWER 9AC is a less portable party speaker alternative to the JBL PartyBox 720. As the name implies, the Sony speaker runs only on AC power, limiting its use to indoor locations and outdoor areas reachable with a power cord. Looking past this, there still aren't many reasons to favor the Sony. It has a similar top volume to the JBL with worse directivity. That said, the Sony does offer more balanced and well-controlled mid and treble ranges, so sounds like voices are reproduced more accurately. Both are solid options for your next karaoke event, but the JBL has a bit more versatility for outside use.
