SDR-15 | 15" 1,200 Watt Max Power Car Subwoofer

MSRP: $ 199.99

Coil Configuration
  • The Skar Audio SDR-15 D2 subwoofer was designed to redefine the term "daily" subwoofer, both in terms of power output and acoustic responsiveness across the entire low end frequency range. The engineering considerations that went into developing this 15-inch subwoofer are extensive, and contribute to why the SDR series has continued to be one of the most popular subwoofer lines we have ever released.

    Featuring a 2.5" 4-layer high temperature copper voice coil, the SDR-15 can operate at peak performance for hours on end with the peace of mind knowing that it can handle the brutality. Combine that with the top-tier, high flux ferrite motor of this driver, and it is by no surprise that this subwoofer can reproduce low end bass frequencies with authority. Furthermore, we integrated a unique red nomex spider suspension system into the design that utilizes the perfect blend of stiffness and flexibility. The aforementioned components of the SDR-15 as well as its advanced air flow cooling design, are what ultimately allow for the incredible responsiveness & power handling of this subwoofer.

14 out of 10 I definitely recommend

4 SDR 15s on a 4500 skar amp 4 6.5 skar door speakers in a 99 3/4 ton suburban box hadn’t been in the vehicle for but a week and already took a chunk of glass out the windshield along with the rear view mirror. All in all amazing quality of sound and feels from skar audio systems for their prices. I’m very pleased by the products

These subs get down... great quality even better pricing..

I ordered 4 15 in sdr 2ohm subs to put in the back of my suburban. I'm super surprised that they hit as hard as they do for the price I paid for them. I built my own box tuned to 33 hz. Use the website box specs to build the box. I paired the 4 subs with a different brand amp currently. The subs just take your breath away. I don't thing there is a bolt I haven't tightened on my suburban. Even had the replace the tail light component be cause I vibrated the panel apart. If your building a budget system and want great sound quality with great pricing I highly suggest giving a set of Skar subs a try...
