The Definitive Technology StudioMonitor 450 is a compact, high-performance bookshelf speaker designed to work as a stand-alone speaker. As an upgrade from the 350, the StudoMonitor 450 hosts a larger 6-1/2” HD bass/midrange driver pressure-coupled to a larger 10” bass radiator, resulting in a wider frequency response (24Hz-30kHz) and a higher power handling level (225 watts). Like its predecessor, the 450 sports monocoque cabinets with a piano-gloss black lacquer and cap/wraparound grille clothe styling that, along with the narrow baffles and radial edges that reduce diffraction and resonant vibration, thereby ensuring high-quality audio. Included also is a 1” moving coil dome tweeter made out of pure aluminum and engineered to ensure linear movement and a smooth extended frequency response. Available only as a matched pair, the 450 comes with shelf- and wall-mounting hardware.
