6.5 Inch (165 mm) XBL² High Excursion, Low Distortion Woofer

MISCO has taken the XBL² technology and executed with effectiveness and elegance in the BWX-6501 (82109), 6.5” woofer. By using a high energy neodymium ring magnet, a high BL is maintained while the magnet structure size and weight is minimized. Yet the Klippel verified, linear XBL (BL force displacement) is over 10 mm. The light weight, copper-clad aluminum voice coil travels in a double magnetic gap. It is centered within inner and outer inductance modulating elements to reduce inductance. This is an ultra-low distortion woofer and allows for a wide range of cross-over points.

• XBL² motor design with 10 mm linear displacement, XBl 
• Abaca fiber cone body with damped rubber surround
• Dual inside-outside copper shorting rings for ultra-low distortion
• Aluminum phase plug for reduction of acoustic-wave energy interference
• High energy neodymium ring magnet for lighter weight XBL² design
• Designed and assembled in the USA

Bold North Audio products are the most accurate, engineered audio transducers available. Each design requires Klippel vibrational test analyses to verify the key parts of optimal audio performance. While we rely heavily on objective science to lead us, we understand that most of all speakers need to tell the musical truth. Our engineers, musicians, and recording studio veterans are the final judges of when a design is worthy of the Bold North Audio brand.

All Bold North Audio products are assembled in Minnesota, with parts sourced from around the world to produce the highest combination of performance, consistency, and customer value.
