Tonewinner SW-D9000 18" Subwoofer

I contacted Amir to inquire about the Tonewinner SW-D9000 18" subwoofer. He was very helpful, spending considerable time answering all my questions in detail. Based on his guidance, I decided to purchase two D9000s for my home theatre, which measures 12’ wide, 18’6” long, and 7’6” high. Amir’s service was outstanding. Delivery was prompt and he provided hands-on setup assistance. It was an absolute pleasure dealing with him and I would not hesitate to give him my highest recommendation.

The subwoofers arrived very well-packaged and in flawless condition. Given their size and weight, we unpacked them in the garage before moving them into the house. Getting them down to the basement was a challenge and definitely required at least two people. Setup, however, was straightforward, and the Tonewinner app proved to be intuitive and reliable.

I tested the D9000s with several movie clips featuring intense low-frequency effects. The results were nothing short of spectacular; the bass was deep, powerful, and effortless. Music with heavy bass lines was equally impressive, delivering tight, controlled, and impactful low end. My only concern was the basement walls rattling under the sheer output. I owned many top-brand subwoofers in the past, including companies like Paradigm, SVS, and Funk Audio, and in my opinion the D9000s rate right up there with the best at a fraction of the cost.

Really enjoying this sub! Nice and deep, surprisingly faster musically than I expected. Thumbs up!

A while back I purchased a D6000 and loved it. When I decided to add another sub to the mix it was going to be another 6000. As I am within driving distance to Summit Hi-Fi I drove down to pick it up. Aamir showed me the 9000 and I was blown away by the sheer authourity the beast exuded. Aamir said that as well as the 6000 performs, that this was on another level. I was sold and I am so glad that I decided I had to have it. This thing is incredable. Thank you so much Aamir, you have put a smile on my face yet again.

But you will absolutely love this sub!! I haven’t even fully dialed it in yet and it is already amazing! And I mean knocking the pictures off your walls amazing! Digs so deep effortlessly, you will feel the movies like never before! I haven’t leaned hard on it yet but we’ve still had to go around the house straightening the pictures. Aamir has been incredible from start to finish and he has made me a customer for life! Could not ask for, or even imagine better service! Thanks Aamir!!

Deep and loud bass. Gets low in the frequencys just the way I wanted it to. Awesome subwoofers!
