Check out a sub on this site for sale from Adire. It is sealed with a 15" driver. The price is right too. I have their Rava which is a sealed 12". I have had it for years and works great. I also have a second sub from Hsu going in my room. The 2 together fill my room with great tight slamming bass. I have no doubt however that 4 would be fun.
Accurate non-boomy sub for satellite system
Looking for recommendations for an accurate, non-booming sub for use in a medium sized room with very small satellites. I tend to believe that a sealed enclosure design is preferable. DIY is not out of the question either (as a I have a solid plate amplifier on hand...but would need driver and cabinet recommendations. Thanks.
