Description

Home Theater Series 1.5k Neo Carbon Fiber

For customers seeking the highest level of performance, the optional carbon fiber composite cone and dust cap upgrade provides increased stiffness, improved strength-to-weight ratio, and greater resistance to cone flex under extreme power levels. These characteristics can improve sensitivity, transient response, accuracy, and long-term durability while helping maintain exceptional linearity at high excursion. The result is tighter, cleaner bass reproduction with lower distortion and increased output efficiency. While our standard paper cone remains an excellent performer, the carbon fiber upgrade is designed for enthusiasts looking to extract every last bit of performance from their system.

Conservatively rated at 1500 watts RMS and perfect for sealed boxes, ported boxes, and other applications. Custom designed and built by hand in the USA. All of our magnets are machined in-house using low carbon American steel. The new 2026 Series 1.5k’s are made with 6 large 1.5″ diameter pillar’s of N52 Neo-Magnets on low carbon posts increasing BL and providing greater sensitivity than previous models. The series 1.5k feature 3″ four-layer copper wire voice coils are wound on .010 tempered aluminum formers rated at 360°c (680°f). These are the highest temp coils available anywhere.
