DS18 PRO 6.5” High Sensitivity Professional Mid-Range Loudspeaker 150 Watts Rms 4-Ohm

Bring your sound system to life with the DS18 PRO 6.5” High Sensitivity Professional Mid-Range Loudspeaker 150W RMS 4-Ohm. Built for detailed midrange performance, this DS18 6PRO300MR-4 is designed to deliver powerful output, clear vocals, and smooth sound reproduction for high-performance audio setups.

With a 6.5-inch nominal diameter, 4-ohm impedance, and 150W RMS / 300W max power handling, this loudspeaker is made to perform with precision and consistency. Its 102dB sensitivity helps it produce loud, efficient sound with less power, making it a strong choice for demanding systems that need clarity and impact.

The 100Hz–12.5kHz frequency response allows this speaker to cover the critical midrange area with excellent accuracy. A copper demodulating ring helps reduce distortion and improve linear performance, while the curvilinear paper cone supports better dispersion and responsive sound. The 1.25-inch Kapton voice coil, steel basket, and ferrite magnet work together to create a durable and reliable speaker built for long-lasting use.

Ideal for anyone searching for a DS18 Pro 6.5, DS18 mids and highs, or a high-output DS18 mid range 6.5 speaker, this model is a strong upgrade for systems that demand both efficiency and clarity.
