Sony ULT Tower 9 short review
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Sony Ult Tower 9 surprisingly impressed me after hearing the bass didn't go that deep but most people use it in ULT Mode 2 which is just upper bass with a brighter sound signature. With the Ult mode off this speaker still sounds pretty open with the 4 tweeters and 2 midrange drivers for a widespread but forward sound with the 12.5 inch woofer delivering enough bass to know you listen to a big speaker but not that much of a impressive speaker until you turn on ult mode 1 so whatever room you bring this speaker you will experience a strong 50Hz to punch to feel the vibrations in the air from the bass and the air thelar has enough low end extention to get that 35Hz movie theater experience while bass up to 65 Hz is still very solid. since this version does come with a battery it is very nice to roll from room to room but carrying this speaker outside sucks. Battery life is decent you can get about 3 and a half hours with the volume on 45% but I haven't preformed a real stamina test yet. It sounds a lot more open than the JBL Partybox 520 but the 520 is much better suited to be on the go and deliver much stronger low, sub bass but then again it can distort a lil while the Sony keeps its composure except for rapidly turning the volume up or down then youll here pops. So I can recommend this speaker as a large indoor party speaker with great sound and a lovely light show

10 Stars! A Speaker That Truly Delivers
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.10 Stars! A Speaker That Truly Delivers I absolutely love this speaker! The sound quality is phenomenal—so much so that I’m already planning to buy another one to gift a friend in Africa. It’s that good. When I returned to Best Buy to pick up my iPad A6, one of the staff members asked how I liked the speaker. I told him it was amazing—actually, I said, “It’s a blast!” and his reaction said it all. Before purchasing, I asked the store manager which he’d choose between the XP700 and the ULT Power 9. He smiled and said, “Why would you go for something less?” We both laughed, and I knew I was making the right choice. This speaker has exceeded all my expectations. It’s powerful, clear, and perfect for any celebration. If you’re thinking about it—don’t hesitate. Treat yourself to a blast this New Year 2026. You won’t regret it!

The 360° Party Sound fills the entire space evenly, making it feel like a live concert no matter where you’re standing, and the 360° Party Lights add an exciting atmosphere that instantly elevates any gathering. The bass is deep and punchy without overpowering the music, and the sound pressure stays strong even at higher volumes.

Sony Ult 9 tower is Ultimate speaker 2Me
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I read and watch videos and read some more about the Sony ult 9 tower to make sure that I was getting the speaker I really wanted especially for my ears and the way I like music to hit. I also read up on the JBL 720 and 520. Everybody says the JBL hits harder and has better Bass but after getting the Sony i don't think so plus the Sony has way better mid-range and doesn't sound so Brassy. The sunny is very well balanced but it hits hard too and I mean hard even if I don't use the ult button it still hits hard but if you need that extra hard hit ult 1 or ult 2 will give it to you. Sony thank you job well done can't wait for the follow-up please add USB C and what would put it over the top is be the first one to give us a remote oh one last thing if you can make the volume increments a little bit more meaning more choices between the levels that you have now that would also make it the bomb! I definitely buy another one if they added those features

Posted .Thank you for the fantastic review, KennK!
We are absolutely thrilled to hear that you did your research and chose the SRS-ULT900 tower, and that it perfectly delivers the sound profile you enjoy! It is incredibly rewarding to know that you find the sound very well balanced with way better mid-range compared to competitors.
We designed the ULT POWER SOUND series to deliver hard-hitting, powerful bass, and we are delighted to hear you agree—even without using the ULT button! We appreciate you confirming that ULT 1 or ULT 2 gives you that perfect extra punch when you need it.
We also appreciate your extremely valuable feedback on potential enhancements for the follow-up model.
This type of specific feedback is instrumental to our engineering teams as they develop future generations of the ULT series.
Thank you again for making Sony a part of your music experience and for your strong recommendation!
