The MBL 121 Surround is a compact, high-performance 3-way loudspeaker designed for surround sound systems. It features MBL's signature Radialstrahler technology with a midrange/tweeter array that radiates sound omni-directionally, creating a wide and holographic soundstage. The speaker includes front-vented, double side-mounted push-push 5.5-inch aluminum woofers crossed over at 600 Hz and 3500 Hz, delivering clear and dynamic bass and mid-bass frequencies. The 121 Surround is finished in high-gloss piano black lacquer or satin finishes with veneer options, and it comes with stands and crates for protection and optimal placement. It is well-suited for use in Dolby Digital and DTS 5.1-channel surround sound setups, providing precise directional sound with minimal localization artifacts. The speaker has a frequency response from 49 Hz to 30,000 Hz, an impedance of 4 ohms, and can handle continuous power of 280W with peak power up to 1000W. Its acoustic center is at 109 cm, and it is praised for its exceptional imaging and wide sound dispersion.
