Product details

SB Acoustics SB15NAC30-4 5'' Mid-Woofer

SB Ceramic cones consist of an aluminum/ceramic dual layer cone. Ceramic provides a very hard and robust surface with improved sonic properties and cosmetic appearance.

Other than that, ceramic cones offer smoothness and harmonic richness unavailable from conventional paper cone material. Ceramic materials also offer significantly higher stiffness numbers and slightly better internal losses than typical metals such as titanium or aluminum. Compared to polymers, paper, and other soft materials, ceramics provide: significantly higher stiffness to weight ratio, more consistent performance over a wide range of temperature and humidity as well as superior immunity to UV light and sunlight, to water and salt water and to combustibility.

Good construction and very good sound! Good price too! Seller send fast. I compared with Scan-speak 15M/4531K00 and the sound is much better than Scanspeak and the price is more cheap at SB Acoustic
