One of the best subs out there if you require a small sub. That is what you are paying for. If you can go bigger, you will pay a lot less for similar if not better performance. If you need to stay small you will be very happy with it. You might also want to compare it to the Velodyne SPL-1200R or the Sunfire Signature. The Velo is a little cheaper and the Sunfire is a little more expensive, but in my opinion these are the three best small subs. Originally when I was looking at subs of this size/price these were the top three for me. I would have chosen the Velo if I had not decided to go with a larger sub.
