From the Manufacturer

Eminence Guitar Legends are specially designed for electric guitar amplifiers. Tuned by skilled ears, these hand-built specials feature a range of materials and ideas from nearly 40 years experience. Models such as the LEGEND B15, 121 and Modeling 12 are state of the art designs which meet the modern-day demand for power handling while other models feature vintage magnet and cone materials to recreate the traditional sounds of lead and jazz guitar.
The most difficult aspect of presenting a guitar speaker to the world is being able to describe its tonal characteristics. Your choice of guitar speakers is at least as important as your choice of pickups or strings. Just as you customize a guitar to suit your sound, so too can you customize -- or 'hot rod' -- your combo with Eminence loudspeakers.

Product Description

With a cast aluminum frame 2 5 inch voice coil and 300 watts of power-handling this speaker is the best choice for the serious player! Many bassists have historically chosen 10 inch speakers in their rigs for their distinctive tonal characteristics but more often because they result a much lighter and smaller cabinet There is however no substitute for a larger format woofer when you are trying to produce bass! Available in 8 ohms The CB15 provides the best of both worlds by punching out low-end that only a 15 inch woofer can provide but doing it in a smaller enclosure Use one driver in a 2 cubic foot box or two in a 4 cubic foot box This bass woofer works nice by itself or when used in two and three-way bass rigs
