Description

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)

    Insanly Heavy & Beautiful

    I jus bought 2 of these awesome monsters, and they came pretty quick,great company n will B buying from then again n again,haven't got them put in yet, just ordered 2 5,000 watt Planet Audio Mono amps to data link together to push these sexy bruisers,they are truly heavy 75lbs each,n getting a 8 cu/ft per side ported box made for them,can't wait,I've owned and seen n been around a bunch of different subwoofers and these by far have a magnet size unlike no other,they are beyond huge I couldn't believe my eyes,right now I'm running 2 12 inch Kicker Comp VR'S n a ported box n 2 15 inch Kicker Solo Baric L7's n a 4 cu/ft box,I'm giving my wife the 12's n putting these crazy huge 18's wit the 15's,after I remove the back seat in our 2000 Chevy Express High Top van, it already beats crazy hard but I know these will rule anything else around, n I've also upgraded my alternator frm the stock 110 amp to a 300 amp n dun the Big 3 upgrade, but if your looking for a sub that looks way better n built with true quality look no further,I'll post an update after I get them installed,, and all I can say is I'm truly satisfied wit them n the pictures of this sub doesn't do them justice, they're very very impressive in person, everybody who's seen mine drops their jaw
