Posted .Hi KristopherS,
It is most rewarding to hear that the ULT TOWER 9 is delivering the clear sound quality and powerful bass you were looking for! We are glad the improved balance of the wheels is making it even easier for you to move the party wherever it needs to go. This speaker truly stands out with its 360° Party Sound that fills every corner of the room and the ULT button, which gives you two distinct bass-emphasized modes for a massive, cinematic audio experience.
Thank you for trusting Sony!
Regards,
Dominick

Sony ULT TOWER 9: The Ultimate Audio Powerhouse
||Posted . Owned for 1 month when reviewed.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.

The Green Experience is Yard Party Ready!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Ult Tower 9 Party Speaker has been a great addition to our supply inventory. The set up to use with iPhone was seamless, battery life is good, and the sound quality is great! We have a nice size yard ( 2 acres) and can hear music at every corner without the volume up to full capacity. I was concerned about disturbing our neighbors and needed to see how far we could walk away from the house and still hear music. We made it to the bus stop which is around the corner about 5 houses away before the sound faded even though we could still hear the bass. Soon after, a neighbor called and asked my husband if he was playing music. The tower was not turned up to full capacity, it was the bass. A few adjustments to the settings corrected that issues but, I knew then we were Yard Party Ready! I would also like to thank Rochelle Sawyer at store #299 in Raleigh, NC. It was Rochelle’s first day and I must say her enthusiasm to assist was amazing. The fact that she was honest about it being her first day and getting additional assistance after trying to troubleshoot the issue was appreciated. To be honest, several employees walked past us as we were trying to test the display and she was the only one that asked if we needed help. Thank you again Rochelle for your assistance!!

Nice bump, nice upgrade
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a upgrade to the 900 model. When i tell you that they could have put this in its own category. The sound is soooo much better than the 900. The bass is unbelievable. Very nice highs and lows. This one speaker sounds better than the 2 900s that i got. You will not be disappointed if you decide to purchase this unit. With that said, you also have a choice,. You can get the ac only or you can get the one that has battery and ac. With the battery version, you get up to 25hrs of play. Will you really get 25hrs? I dint know, but i do know that you throw a party and it will last more than 5hrs on a charge. It also have a quick charge so if it does die, you would only be down for 5min at the most and you will be right back to the powerful sounds of this sony beast. Highly recommended.
