ACV STEIN subwoofer was developed to provide the perfect combination of SQ/SPL qualities in its power class. With 4500W peak and 1500W RMS power, STEIN S15D2 has no rivals when it comes to overall performance and connectivity with other components. When developing the product, German engineers paid special attention to TS parameters and strict build quality to achieve the highest possible sound pressure.

The STEIN subwoofer is quite versatile and will sound great in a wide range of music genres. STEIN subwoofers uses a top performance upgraded high temperature 3" 4-layer double BASV voice coil, wound with round copper on the aluminum bobbin to increase the subwoofer's endurance and durability for everyday use. The model features integrated 153 ounces Y40 high-flux ferrite magnet, an ultra-wide stitched foam rubber surround, in tandem with a competition-grade cone and a triple "CONNEX" centering washer, it sets a new precedent in terms of sound quality and power.

STEIN subwoofers are successfuly used by car audio sportsmen in various car audio competitions and are widely recognized for their high performance and reliability in their class.

Impedance 2+2 Ohms makes possible to connect equipment in accordance with a wide variety of connection schemes, which provides flexibility and convenience in its use.

Dual voice coil means double power, double efficiency and connection flexibility.

The cone with a larger sound emitting area allows you to achieve deeper and lower sound. The increased cone area makes it possible to get maximum sound pressure level SPL.

Quality push terminals make subwoofer connections quick and easy. Installation of 8Ga power cable in one click of the terminals - then the terminals tightly and reliably fix the connection.
