    Incredible audio quality, battery life, connectivity, and functionality. Zero complaints as of yet. It's big, but overall proportioned nicely and not an eye-sore. Huge fan, and a justifiable cost in my opinion... I kinda want another

    Wow! You xan actually feel the bass in uour chest, the sound isnt distorded when you turn it up, i have only turned it up a little over half way, if you know how to set your equalizer on your iphone in the music app and the equalizer from the app, the battery last for days, i listened to it for 18 hrs straight with no problem, just have the stamina setting on and you will be amazed, the price for the speaker is worth every cent, theres no comparison to the sound this speaker puts out! Impressive! All tbe way around, And dont forget to face it towards the corner of the room you’re playing it at, and Wow! Is what you’ll say! Guaranteed! Hopefully this review makes someones decision easier to make.

      Thank you for that incredible review, H3RN4ND3Z! We are beyond pleased to hear that you are so impressed with the SRS-ULT9000 and that you can literally feel the bass.

      The ULT POWER SOUND series is designed to deliver that powerful, chest-thumping bass without distortion, even when you turn it up. It's truly rewarding to know you're getting so much enjoyment out of the speaker. We also love that you're using the Stamina setting to get days of battery life—it was made for those long listening sessions!

      Thank you so much for your detailed feedback and for the pro tip about the corner. We are sure your review will be a huge help to others looking for an impressive speaker.

    The Sony ULT Tower 9 is one of the most impressive party speakers I have used. From the moment I turned it on, the powerful bass and room-filling sound stood out. Sony's ULT Bass mode delivers deep, punchy low frequencies that make music feel energetic and immersive, whether you're listening to hip-hop, EDM, or pop. The 360° Party Sound feature helps spread audio evenly throughout the room, ensuring everyone enjoys the same great experience.

    Very capable speaker. We got 2 for use in stereo pair outside with the projector and for parties around the pool. There are issues with the app sometimes not allowing me to connect two together. That would give me 4 stars but the speakers pair buttons work just fine so it’s no issue. The speaker resets everything to defaultbsonifnyou need less bass and set the bass eq lower through the app you will have to do it every time. Will update when we ensure the optical out in the projector works with the speakers being in stereo pair mode No other speaker has optical out and we were sold on the 25 hour battery functions

    Sony ULT TOWER 9: The Ultimate Audio Powerhouse

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The Sony ULT TOWER 9 is an absolute beast that has completely transformed my home setup. Whether I'm hosting a party or just relaxing, this speaker delivers in every category. Massive Sound: The audio is crisp, and the ULT button provides a deep, chest-thumping bass that fills the entire room. Cinematic TV Audio: I’ve hooked it up to my TV, and the TV Sound Booster adds a rich, theater-like layer to movies and sports that built-in speakers just can't match. Karaoke King: This is my go-to for karaoke nights. With dual mic/guitar inputs, echo controls, and 360-degree lights that sync to my voice, it feels like a professional setup. Final Verdict: From music to movies to late-night karaoke, the ULT TOWER 9 is the best investment I’ve made for my home entertainment.

    So far so great! The sound is clean. The bass in the ult 1 & ult 2 id more than enough. The battery life is very accurate; but all depends on how loud you listen. To be honest, I can’t turn it more than 30% because it’s loud and clear enough for me. We’ve been singing karaoke out from the thing for 2 plus hours every now and then. I like it a lot and glad didn’t go with the 520 Partybox; too much bass.

    [Employee of bestbuy] Like what the title say. You can't really get better sound quality for the price. I've had JBL, bose and other home theater equipment for comparison and the Sony one is a league above in terms of music quality and impact. It gives you the feel of a much higher quality dedicated tower speakers with amplifiers. Bass is surprising for its size. Added bonus for mic inputs and optical.
