The Mission MS-400 Sub is a powered subwoofer in the MS family, which Mission arranges as a graduated ladder by output and cabinet size. It sits above the MS-200 Sub, in the middle of the numbered MS lineup.
Key specs that matter
Response extends from 35 Hz to 120 Hz. Its internal amplifier is rated at 215 W, lower than the 350 W of the LX-10 Sub. The cabinet measures 40.2 x 35.2 x 37.5 cm and weighs 14.6 kg, making it more compact and lighter than the LX-10 Sub.
Pairing
The MS-400 Sub takes its feed from line-level or speaker-level connections, which lets owners pair it with a two-channel amp just as readily as with an AV receiver offering a dedicated sub out.
Alternatives
The Mission MS-450 Sub sits one step higher in the MS range for buyers who need more output.
