The new sub is designed for maximum placement flexibility.
The SB-900 is one of Atlantic's most popular subwoofers, but it's not the kind of sub that works for everyone or, more to the point, not the kind of sub that works for every room. Atlantic knows this, and has created a new down-firing version for those that want to place their sub in a less traditional location.
Like the original SB-900, the 900DF uses an 8" woofer to give you a bass response as low as 32Hz, while distortion detection technology helps to limit distorted audio . The sub is powered by a 125 watt amp and has a peak output of 102 dB SPL.
You can pick up the SB-900DF at the same $349 price as the SB-900.
