DELTA 15 LF RAW FRAME DRIVER: OVERViEW: Pressed steel loudspeakers have been the backbone of Eminence Speaker LLC for nearly 40 years. You could say we have had a lot of practice at making these! This is our signature range of loudspeakers. A series fashioned by a team with more combined experience in loudspeaker design than any other team in the world. A group of people who, collectively, have created over 6,000 different loudspeaker designs - and that's only the number that made it to production! Every one of these loudspeakers has been designed and carefully built by individuals for whom developing loudspeakers is a way of life. We think it shows. We know you can hear it too. Take a look at some of the remarkable performance figures. Eminence pressed steel baskets possess remarkable strength and are often stronger than the cast frames of other manufacturers. The voice coils in this series are among the best in the world. They are responsive and durable - designed to make the best of the available amplifier power and to faithfully reproduce music.MADE IN THE USA: The advances made since 1966 have been significant and even in the lifetime of this range, our philosophy of "making a better speaker for less" holds true. In particular, detail changes in our voice coil assemblies have increased thermal efficiency. As a result, power ratings have improved by up to 100% or more in some cases. The Kappa models, once rated at 400W across the board, are now rated at between 450W and 600W. The Alpha models, once rated at 100W, are now rated at between 100W and 200W. The Beta 15 was originally rated at 150W but has been re-engineered for a massive 350W! To recognize these new models, look for their chrome back labels.LF Features: Eminence LF models are specially designed with extended Xmax to deliver more bass than standard models and provide 'a true woofer' for three-way applications.
