Reiss RS-M85DM

Reiss RS-M85DM – 8" Midrange 350W RMS with High Efficiency and Powerful Precision

Reiss RS-M85DM is an 8-inch midrange driver designed for those who demand high sensitivity, strong presence and clean reproduction even at extreme volume levels. With a robust build, advanced materials and carefully tuned acoustic design, it delivers a clean, dynamic and powerful midrange response. The RS-M85DM is ideal for both SQ and SPL setups where performance, control and durability are essential.

Performance with power and control

With a power handling of 350 W RMS and up to 700 W max, the RS-M85DM plays loud and clean without losing control. It operates within a frequency range of 90–8000 Hz and offers a high sensitivity of 97 dB, making it extremely efficient even with moderate amplification. With a 4 Ohm impedance and a resonance frequency of 90 Hz, it delivers powerful midrange performance with fast attack and clear presence.

High-quality construction

• Cone: Reinforced pulp paper cone for low distortion and a natural tone
• Surround: Treated cloth surround for controlled movement and long-term durability
• Frame: Steel basket providing high rigidity and vibration-free performance
• Magnet: Ø145 mm ferrite magnet for strong magnetic force and stable reproduction
• Voice Coil: 50.8 mm high-temperature copper coil for efficient cooling and thermal stability

Engineered for precision and dynamics

The RS-M85DM combines low moving mass (17.6 g) with precise suspension and a powerful motor structure, resulting in fast response and distinct impact in every note. With a Vas volume of 12.6 liters and QTS of 0.419, the driver is optimized for smaller enclosures or open baffles where efficiency and control are key. Its large diaphragm area of 243 cm² contributes to a full and direct midrange with excellent dispersion.

Installation and dimensions

The RS-M85DM is designed for easy integration into professional and advanced audio systems. It features an outer diameter of 217 mm, mounting depth of 88 mm and a cutout diameter of 186 mm. With a weight of 4.1 kg, the construction reflects solid build quality and carefully selected materials – built to perform under heavy use.

Reiss RS-M85DM is the choice for those who want high efficiency, clear attack and long-lasting reliability – a midrange driver engineered to deliver precision, impact and musical strength in every note.
