This is really affordable subwoofer for anyone and definitely it's reasonable price for such a great product. I use it in my homestudio and it works fantastic with my Behringer Truth B1031A's. It packs enough punch and clarity you need to deliver successful mixes or just to enjoy music. The lower frequencies are also so powerful it made the entrance door of my apartment to vibrate!
You got all the necessary adjusting features in the backpanel of the subwoofer.When I first time tested it, I noticed that the balance between the pair of monitors and the woofer was nicely even. The corssover adjustment was indeed a bit complicated to understand, because this sub was apparently designed for use with the Behringer K-series. I found the perfect setting when I read about the K-series and chose the option that was as near as possible to my own speakers. Though, this isn't the only way to find the sound that fits to your room. The range of tonality adjustment is good also! Phase correction is also simple and effective in this product; you can actually hear the difference.
It is a stable subwoofer that you don't need to worry about resonating through your floor: The "rubberpaws" eliminate well all the resonating and vibration, making it sound clean.
Overall it is a fantastic piece of equipment in it's price range.
