Eighteensound 18W1001

This 18-inch woofer is primarily designed for high-output subwoofer applications. It performs best in vented enclosures where its 4-inch voice coil and ferrite magnet can effectively move air for deep, punchy bass.

While the frequency range extends up to 4,700 Hz, this driver is optimized as a dedicated woofer or subwoofer. For professional setups, it is best paired with a high-frequency compression driver or tweeter to handle the upper registers.

The 18W1001 is rated at 1000W AES. To achieve its full potential and maintain clean, undistorted output, you should use an amplifier capable of delivering 1000W to 2000W of continuous power at 8 Ohms.

The speaker features a robust, professional-grade construction, but it is not inherently weather-sealed. If you plan to use it outdoors, it must be housed in a protective, moisture-resistant enclosure.

The large 4-inch voice coil is essential for thermal management and power handling. It allows the speaker to maintain consistent performance during long periods of high-volume use without overheating or losing efficiency.

Ferrite magnets are heavier than neodymium alternatives, and this unit weighs 12.9 kg. Ensure your mounting baffle is constructed from high-quality, rigid material like Baltic birch plywood to support the weight and handle the significant acoustic pressure generated.
