Different sizes. The ULT Tower 5 is a 28 lbs (12.7 kg) party speaker with a removable battery. The ULT Tower 10 is a 63.9 lbs (29 kg) large party tower with no battery. Each is rated within its own class.
The Tower 10 is louder than the PartyBox Ultimate and includes a wireless microphone, but its bass drops off a lot at high volume.
The Tower 5 claims 20 hours from its removable battery, is IPX4, and has balanced XLR, RCA and mic inputs.
Buy the Sony ULT Tower 5 at $448 if you want a party speaker. Buy the Sony ULT Tower 10 at $994.34 if you want a large party speaker instead.
