Sony introduced three new ULT Tower party speakers on September 1, according to Tom's Guide and Engadget: the ULT Tower Max, ULT Tower 7, and ULT Tower 5. Both outlets describe the lineup as Sony's next generation of large-format party speakers, aimed at DJ setups, karaoke, and portable high-volume audio rather than casual desktop listening. The common feature set is connectivity-heavy. Engadget reports that the new speakers include XLR, RCA, and USB-C ports, while Tom's Guide says the lineup also includes USB-A. Both outlets frame those inputs around practical event use: microphones, DJ hardware, mixers, instruments, and karaoke. Engadget also says the speakers can work with Sony's ULT MIC1 microphone. The most notable wireless addition, according to Engadget, is a new Party Chain feature built on Bluetooth Auracast. Engadget reports that the speakers can be linked wirelessly for multi-room audio, but says that, for now, the Auracast implementation is limited to the new speakers and will not wirelessly connect with older Sony party-speaker models. Tom's Guide says it listened to 10 of the new speakers together at a pre-launch event, but the provided text does not specify that the demo used Auracast. Sony also moved more sound control onto the speaker hardware. Both Engadget and Tom's Guide describe a front ULT control that switches among four equalizer presets: ULT1, ULT2, Flat, and Live. The sources describe ULT1 and ULT2 as bass-oriented modes, Flat as a more source-faithful setting, and Live as a more spacious or performance-style presentation. Engadget provides the clearest pricing and replacement map. It says the ULT Tower Max costs $1,500 and replaces the Tower 10, the ULT Tower 7 costs $650 and replaces the XV800, and the ULT Tower 5 costs $450 and replaces the XV500. Tom's Guide similarly positions the speakers as a new generation that builds on earlier models such as the Tower 10, but the provided text does not include the full replacement list or pricing. The models step down in size and battery claims. Engadget says the ULT Tower 7 has an IPX4 water-resistance rating, upgraded wheels, Sony's 360-degree Party Sound technology, and up to 30 hours of battery life per charge. It says the smaller ULT Tower 5 is also IPX4-rated and runs for around 20 hours. Tom's Guide says all three models are IPX4-rated, describes the lineup as splash-proof, and notes that the speakers use handles and wheels for transport. There is one material spec conflict. Engadget describes the ULT Tower Max as using a rear woofer, four tweeters, and a mid-range speaker, while Tom's Guide says the Max packs three 280mm woofers, two mid-range drivers, and four tweeters. Tom's Guide also reports that the Tower 7 uses one 280mm woofer, two mid-range drivers, and four tweeters, and that the Tower 5 uses a 230mm woofer, two mid-range drivers, and two tweeters. Until Sony's published spec sheet is checked directly, the Max driver count should be treated as unsettled in this cluster. Who benefits: Sony benefits if the lineup gives buyers a clearer upgrade path across $450, $650, and $1,500 party-speaker tiers. Event hosts, karaoke users, and mobile DJs get more input options and hardware EQ controls in the new models, according to both reports. Who's exposed: Owners of older Sony party speakers may be exposed to compatibility limits, because Engadget reports that Auracast chaining is only integrated with the new models for now. Buyers who need heavy outdoor use should also note Tom's Guide's point that IPX4 is splash resistance, not a higher weatherproofing rating.
