Description

The Reiss RS-M85DM is an 20 cm (8") midrange speaker designed for those who demand high sensitivity, strong presence, and clean reproduction even at extreme volume levels. With robust construction, 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.

With a power handling of 350W RMS and up to 700W MAX per speaker, the RS-M85DM plays loud and clean without losing control. It operates within a frequency range of 90 to 8,000 Hz and offers a high sensitivity of 97 dB, making it extremely efficient even with moderate amplification. With a 4 Ohm impedance and a resonant frequency of 90 Hz, it delivers powerful midrange performance with fast attack and clear presence.

The reinforced paper cone provides low distortion and a natural tone, while the treated cloth surround ensures controlled movement and long-term durability. The steel basket offers high rigidity and vibration-free performance. The Ø145 mm ferrite magnet provides strong magnetic force and stable reproduction. The high-temperature 5 cm (50.8 mm) copper voice coil ensures efficient cooling and thermal stability.

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