REDCATT 181XR - 8 Ohm Woofer

Key Features

• Cone excursion 56mm !! Patented design.
• 1 demodulation copper ring, powerful and innovative motor structure, innovative venting system
• Extra large double spider with spacer, woven-in tinsel wires. Reinforced cone edge, optimized surround

Design Notes

Designed based upon the 18XR, the 181XR was designed for professional audio segment. The basic characters and design concept remains the same for the 181XR. We have used newly designed 4 roll waterproof fabric surround that fully supports the high cone excursions of this incredible loudspeaker. The target was to push the envelope of possibilities We are giving you a product that will not limit you to achieve even your wildest sub-woofer dreams. Motor Design The magnetic design incorporates large neodymium magnets placed along the voice coil winding. This has allowed us to push the cone excursion to 56mm peak to peak. Unique gap venting ensures good air circulation and greatly improves the reliability of this driver. We have also developed a new technique for manufacturing deep copper caps. The design further utilizes dual, uncommonly large, spiders, spaced with spacer, hot-pressed tinsel wires onto the top spider, reinforced cone edge, reinforced surround to cone joint, reinforced spider to basket joints, etc.
