Short answer: the Sony ULT Tower 9, if you are buying new. The Teufel Rockster ranks higher than it (#8 vs #9 of 12 large party speakers, 4.4/5 vs 4.2/5) but is discontinued, so only consider it used; the Sony ULT Tower 9 is still sold new at $898.
Why pick the Teufel Rockster: Teufel Rockster uses 2-way: 1x 15” (380mm) woofer, 1x 1” horn-loaded tweeter. The catch: There is no companion app.
Why pick the Sony ULT Tower 9: Slightly better sounding than the ULT Tower 10. Watch for: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
Buy the Sony ULT Tower 9, since the Teufel Rockster is discontinued and only worth hunting down used.

Sony ULT Tower 9: $898.00 Amazon eBay
Older model: the Sony SRS-XV900 (ranked lower, rated 3.7/5).
Pros: Slightly better sounding than the ULT Tower 10
Cons: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers. Bass drops off a lot at higher volumes. Not quite as loud as the ULT Tower 10
