Selenium by JBL 12MB1200A Speaker (12" Woofer)

The Selenium by JBL 12MB1200A is a 12" woofer for midbass professional sound reinforcement. This robust woofer is capable of supporting 600 watts RMS and is ideal for compact enclosures (closed, vented or horns). High efficiency is achieved through the use of a large ceramic ferrite motor and low mass 100mm (4") diameter aluminum voice coil wound on a fibreglass former. The pole piece also has a ring of short copper to minimize harmonic distortion. The aluminum die cast frame provides the array with high mechanical resistance. This woofer includes an impregnated cloth surround, stable spider and a large central vent channel for reducing long-term heat build-up. The 12MB1200A was developed and tested under the most severe of conditions to ensure a delivery of outstanding midrange and exceptional long term performance.
