Well over one year of development and prototyping has driven the production of the new Crescendo Subwoofers. Designed with the basshead in mind, these subwoofers are destined to become one of the top ground pounding subwoofers available.

The Contralto series is our uncompromising competition certified model, available in 10”/12”/15”/18”

An extremely strong triple stack motor with a solid 1 piece T-Yoke with extended pole propels the Contralto’s 8 layer 3” flatwound coil mated to the lightweight black anodized aluminum former optimized for heat dissipation, with all sizes sporting multiple Nomex spiders for long lasting suspension and precise performance. Power is transferred to the coils with low resistance double stitched tinsel leads, through oversized push terminals, ready for multiple runs of 8awg/10awg in and out. A vented rear pole along with under spider freeflow venting aids in extensive heat dissipation performance.

Up front, a rigid yet lightweight carbon fiberglass/pulp bonded cone pumps out the bass in conjunction with the tall, custom designed treated foam surround stitched for added durability in extreme applications.

Keeping it all in one piece is the custom finished cast aluminum basket, designed for high levels of clearance, airflow and strong enough for any competitor to not have to worry about cracked spokes even with such a heavy duty motor as the Contralto series sports.

The Contralto series is rated at 2500w RMS, with exception of the 10” (1800w RMS, 2.5” coil 8layer)
