SPL-Dynamics Pro 15

DER EXTRAKLASSEWOOFER DRUCK PUR ! wahlweise als 2 x 4 Ohm oder 2 x 2 Ohm Woofer  SPL Dynamics's PRO -series subwoofers with composite cone represents the latest subwoofer technology with new style of cone. New type of cone is manufactured by covering non-pressed paper cone with woven nature Kevlar. Composite cone takes advantages of Kevlar cone and non-pressed paper cone and improves their weak points. It's well damping and ultra-rigid during high excursion. As a result, it delivers ultra-low distortion and fast transient response. It let's you feel clear and pure bass sound. Extended pole piece construction creates an uniform broad, full-symmetric magnetic field for improved dynamic linearity. This additional lenght keeps the voice coil in the magnetic field longer. The results are more excursion, deeper and more powerful bass. It's also dramatically extends X-max. Frames of the new models are CNC-machined.
