Product Description

Contralto 15"s out of stock in ALL ohm loads.

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 15" is rated at 2500w RMS(3” coil 8layer)

Ready for competition in the lanes, with full recone parts stocked in all different ohm load configurations for those competitors who eventually need to recone from throwing 5kw to one of these.

  1. Sounds Amazing and Smashes The Lows!! 5 Star Review

    Posted by on 5th Jul 2017

    Absolutely love my Contralto 15's. They sound amazing and love the lows. Great 4th order sub. Very efficient as well. I switched out from a much beefier sub and was told I was downgrading. Got to throw it in their faces when I actually gained a full DB!! Doing a 152.5 at 31hz from the trunk with 2 Contralto 15's on 2 BC3500's strapped at 1 ohm in a 2:1 4th order rear deck blow thru. I went a head a finished off a full Crescendo build with 6 PWX 8's on a C1600.2 and I couldn't be happier. Crescendo FTMFW!!

  4. SLAMMING & FLEXING 5 Star Review

    Posted by on 31st Oct 2016

    This Contralto 15" D1 I've replaced my Sundown X 12 with is a major improvement! Noticeably louder on similar power.

    Running it at half ohm on a Twisted Sounds TS1.8k (old amp was AQ2200). Mechman 240 amp alt & XS D3400 under hood w/ Big 3 (or 4) and 1/0 awg OFC everywhere. 14.0v+ solid.

    Enclosure is 4 cu. ft. @ 28.3 hz w/ 61.63 sq. in. of port area. I had to remove the trunk latch to slide the box in my Impala but it was worth it! Seems to be working well with the subwoofer.

    Needless to say this thing is loud and is nothing less than expected. Smashing out the lows like no tomorrow.

    Paired with two sets of Crescendo Coaxial speakers in stock locations on a SQ Q90.4 4ch amp. It's heavenly!

    Can't go wrong with Crescendo Audio!

  5. Excellent Subwoofer!! 5 Star Review

    Posted by on 29th Jun 2016

    The 15" Contralto hits extremely deep and low.

    I got the dual 1 and I am running in parallel.

    Giving the sub about 3200 watts RMS clamped and it's taking it with no sweat!

    I have a 5 cubic ft box that is tuned to 36hz.

    You way want to tuned slightly lower but I am happy with that!

    Excellent sub!!

    Give it 2500 to 4000 watts RMS clean power and you will love yours too!!!

    Posted by on 10th Jun 2016

    I loved my 2 15 inch Contrelto subwoofer so much I bought two more! I recommend these to my team my friends or anyone else. Top quality & affordable prices. Loud and clear-ly the logical choice.

  7. amazing 5 Star Review

    Posted by on 11th Apr 2016

    One of the gnarliest subs i've ever seen. can't beat the price for the quality of product you receive. 72 lbs, 4 gauge push terminals, and the motor is the best part. absolutely massive, on low power it has enough beef to back it up. Im giving it rated power, but it can handle easily double that.
