Reiss RS-MB12QS8 – 12" midbass with powerful precision and wide frequency range

Reiss RS-MB12QS8 is a 12-inch midbass driver developed for those who want high sound pressure with both impact and clarity. With a power handling of 500W RMS (up to 1000W max) and an impedance of 8 Ohms, this driver is built to play loud and clean, whether installed in ported enclosures or in vehicle doors with sufficient volume.

The midbass plays from 55 Hz up to 5 kHz, covering both upper bass and a large part of the midrange. A resonance frequency of 56.5 Hz and a QTS value of 0.257 indicate a fast and controlled character, resulting in tight and dynamic performance.

With a 2.5-inch voice coil, a powerful ferrite magnet (Ø 220 mm), and a moving mass of only 50 g, it combines high power handling with quick response. The cone area of 522 cm² and an impressive sensitivity of 99 dB provide excellent sound dispersion and high efficiency, even with limited amplifier power.

Reiss RS-MB12QS8 has an outer diameter of 320 mm, a mounting depth of 126 mm, and a weight of 7.8 kg – a robust construction built for heavy-duty use. This makes it an ideal choice for both competition systems and enthusiast builds where the midbass must deliver high output, sharp attack, and long-term durability.
