About: DS18 6PRO300MR-4 PRO 6.5” 150W RMS High Sensitivity Professional Mid-Range Loudspeaker - 4 Ohm (Each)
Get superior sound with DS18’s 6PRO300MR-4! With its 6.5" nominal diameter and 4 OHMS nominal impedance, the 6PRO300MR-4 delivers exceptional performance and clarity. The RMS power handling of 150W and MAX power handling of 300W, guarantee powerful sound reproduction. One standout feature of DS18’s 6PRO300MR-4 is its high sensitivity rating of 102 dB, allowing it to effortlessly fill any space with rich, immersive sound.
The frequency response range of 100Hz-12.5KHz ensures that every beat is reproduced accurately. What sets the 6PRO300MR-4 apart is its demodulating rings made of copper. These rings play a crucial role in substantially reducing harmonic and intermodulation distortion associated with voice coil displacement. They also minimize the modulation of magnetic flux during the movement of the voice coil, ensuring a more linear variation of system inductances as input current varies.This results in a cleaner sound output, providing an enhanced audio experience.
The curvilinear cone shape enhances overall dispersion while maintaining optimal performance. The push speaker terminals make installation hassle-free, allowing for secure connections without compromising on sound quality. DS18’s 6PRO300MR-4 has one of the most impressive motor configurations in our catalog. Its 1.25" voice coil diameter, made of Kapton material, ensures excellent heat dissipation for extended playtime without any compromise in performance. Experience audio excellence with DS18’s 6PRO300MR-4!
