Reiss RS-MB12QS4 12" Midwoofer 400W 4 ohm .
Reiss RS-MB12QS4 – 12" midbass with power, sensitivity, and a wide frequency range The Reiss RS-MB12QS4 is a powerful and high-resolution 12-inch midbass driver, designed to deliver both punch and clarity in the midrange. With a power handling of 500W RMS (1000W max) and a 4 Ohm impedance, this is a highly efficient driver that excels in systems where volume and presence are key.
Its wide frequency range from 55 Hz to 5 kHz makes it ideal for both upper bass and midrange reproduction. A resonance frequency (FS) of 57.7 Hz, combined with a QTS of 0.242, indicates a fast and controlled driver suitable for ported enclosures or well-sized door installations. With a 2.5-inch voice coil, a moving mass of just 45.86 g, and a large Vas value of 64.3 liters, the RS-MB12QS4 offers dynamic response with sharp attack. A cone area of 522.53 cm² contributes to impressive sound dispersion and efficiency, even at high sound pressure levels.
Reiss RS-MB12QS4 is an excellent choice for anyone building a system where the midbass is expected to play loud, clean, and powerful – perfect for both competition setups and high-performance enthusiast builds.
