The new ASCENDO SV-12 subwoofer sets the standard for bass output, low distortion, and affordability. With chest thumping bass that plays deep down the SV12 subwoofer unleashes cinema level volume, with the ability to convey and articulate the subtle nuances of music.

12" Woofer: At the heart of the powered subwoofer is a composite cone driver with a very stiff sandwich cone paired with a large throw rubber surround. The SV12 12" driver was developed from the ground up, with a design focus on achieving output, accuracy, dynamics, and linearity, while minimizing distortion. Sophisticated computer modeling and measurement techniques are used extensively in the powered subwoofer design process. The woofer is enclosed in a cabinet made from HDF material outfitted with massive internal bracing and dual ports to minimize port turbulence.

500-Watt Amplifier: The 500W RMS amplifier is built around the high efficiency Class D amplifier module based on a proven topology with vast reserves of power for highly accurate, deep bass for your home theater or music system. A Variable crossover with adjustable phase control is used for easy integration with other speakers.

For convenience, an auto turn on/off function was added. Audio can be supplied to the subwoofer by either balanced XLR or RCA interconnects (LFE/line level inputs).

Perfect! Easy, convenient, definitely recommend
Size: 100LBS, Size: 100LBS
I am so glad I found this base that I can just fill with water. After screwing on the wheels, I used my garden hose to fill it with water and put my 1.5 inch diameter umbrella in and tightened it. Easy peasy. I love that it rolls and I can move it wherever I want, and also lock two of the wheels if needed. Definitely would recommend this one!

Happy with my purchase. Sturdy well built, love that it has wheels makes it easy to move around and wheels lock in place. I choose to fill it with sand and water as it gets really windy where we live this will prevent my umbrella flying to the neighbors house again 😅

Must Read before Purchasing!!!! Height is lost if you use this base!!!!
Size: 100LBS
I was so very excited about this for our umbrella - and then I put it together. I called my adult son to come and take a look - I had to be doing something wrong. To our dismay, I was not. The lowest pole in the umbrella system has 4 welded pieces with holes meant to connect to the legs, thus stabilizing the structure. The lowest pole measures (guestimate) 3 feet. When you choose this system, you do not use the original cross-bars, nor the original lowest pole with the 4 welded pieces. Rather, you use a newly provided lowest piece roughly measuring a foot. In doing so, the structure loses a total of almost 2 feet. For average-height individuals, this would not be a problem. For individuals 6' or greater, this is quite a problem. My son is 6'6. My husband is 6'2. I really wanted the portability of the product. However, we will be returning it for the kind that rest on the cross-bars. I wish someone had mentioned this in the reviews I read and saved me the trouble.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.
