Product Description

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! 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. How a Speaker Works The key working components of a loudspeaker are shown in the diagram below. When an electrical current passes through a wire coil (the voice coil) in a magnetic field, it produces a force which varies with the current applied. The cone, connected to the voice coil, moves in and out, creating waves of high and low air pressure. The coil and magnet assembly are the 'motor structure' of the loudspeaker. The movement is controlled by the loudspeaker's suspension which comprises the cone surround and the 'spider'. The surround and spider allow the coil to move freely along the axis of the magnet's core (or 'pole') without touching the sides of the magnetic gap. Eminence technology and proprietary materials mean that age-old 'compromises' of durability against sensitivity, or power handling against precision of response, are more easily solved than you might imagine. Heatsinks : In the quest for higher power density (more power and hence more sound from less space), Eminence has progressively introduced heatsink components to selected transducers e.g. cast frame neodymium products and Kilomax. The heatsinks pass through the pole of the transducer or are incorporated into the chassis of the loudspeaker to transfer heat away from the coil. The air curren

This review is from: Eminence Legend CB15 Bass Amplifier Speaker (15 Inch, 300 Watts, 8 Ohms )

I put this into an Avatar cab that's also equipped with a tweeter, and the combination absolutely rocks. The speaker construction is very solid.
