Big sound. Compact motor. Built to project.

The DS18 8PRO600NSE-4 is an 8-inch professional mid-high loudspeaker engineered for high-output audio systems that demand powerful vocal projection, detailed upper frequencies, and dependable performance. Part of DS18's PRO600NSE series, this sealed-back speaker combines a lightweight neodymium motor structure with high sensitivity and durable construction.

Delivering 300 watts RMS and 600 watts maximum power handling, the 8PRO600NSE-4 is designed for demanding audio applications. Its 98 dB sensitivity helps produce strong output, while the 280Hz to 16kHz frequency response covers the mid-high range needed for clear vocals, instruments, and upper-frequency detail.

The sealed-back construction helps isolate the speaker's rear radiation from the surrounding enclosure or mounting cavity, making it a useful choice for custom pro audio installations and line-array-style speaker arrangements where controlled mid-high output is important.

Inside, a 2-inch glass fiber voice coil former with CCAW winding works alongside an 8 oz neodymium magnet and copper demodulating ring. The curvilinear water-resistant paper cone, cloth surround, and rigid aluminum basket provide a balance of responsive performance and durability.

Rated IP65 for water and dust resistance, the 8PRO600NSE-4 is also suited for installations where exposure to the elements is a concern. Its matte black aluminum basket delivers a clean, professional appearance.

Whether you're building a custom high-output car audio system or a multi-speaker pro audio arrangement, the DS18 8PRO600NSE-4 provides focused mid-high performance with serious power handling in a compact neodymium design.
