The SCANSONIC MB 2.5B is a slim floorstanding loudspeaker designed with two 4.5-inch carbon-coned drivers and a sealed ribbon tweeter. It is a 2.5-way speaker configuration where the second woofer assists in the power-demanding bass region, providing deep and controlled low frequencies. The cabinet is curved, heavily braced, and ventilated, featuring carbon reinforcements for rigidity and reduced resonance. It includes a front-loaded port and adjustable aluminum feet for stability and acoustic optimization. The speaker has a frequency response range of 36 Hz to 40 kHz, an impedance greater than 6 ohms, and a sensitivity of 88 dB. The crossover frequencies are set at 500 Hz and 2600 Hz using a minimum phase design. The MB 2.5B is recommended to be paired with high-quality amplifiers rated above 50 watts. It is available in black-silk or white-silk finishes and weighs approximately 15.6 kg with dimensions of 178 mm width, 998 mm height, and 286 mm depth. This speaker is praised for its sophisticated sound with deep bass, truthful midrange, and silky highs, making it suitable for various music genres in intimate listening environments.
