Audioque Street Duty SDC2.5 Series

The SDC2.5 Series is the latest improvement on our most popular woofer.  We have increased the motor power, throw and upgraded the suspension and cone to give you even more for your money.

The Audioque SDC2.5-D4 subwoofers were designed for today's car audio systems. High powered sound systems require high power subs that are built to handle the load. The SDC2.5 was designed for 500-600 watt per driver sound systems, this matches well with the 500-600 watt mono blocks driving a single woofer, or the 1000-1200 watt mono-blocks driving a pair of woofers.

These subs were designed to hit hard, sound great and last a long time. The 2.5" DUAL voice coil diameter is big enough to handle the long-term power while light enough in mass to yield high output. The coil is coupled to a strong multi-fiber cone that is reinforced with an epoxy resin dust cap.

The EROM, high roll surround is efficient in both excursion and cone area. The suspension follows our philosophy of multiple, high compliance spider layers for tight bass with low fatigue over the long haul. The lead wires are formed into these spider layers which further enhances durability and eliminates lead slap/breakage problems.

The frame is cast aluminum with a sandblasted, powder coat finish. The motor parts are all machined with a black epoxy finish to aid in heat transfer. The tight tolerances of the SD2.5 motor provides high energy without excess weight.

These subs use the finest parts that can be found, are hand assembled to maintain the tightest tolerances and made especially for you. Everything about the SDC2.5 subs is dedicated to delivering the pounding bass you need.

The SDC2.5 series fills the void between the SDC2 series and the HDC3 super woofer. It is the perfect choice for raising the bar in power levels to get that extra bass but still be in the 500-600 watts power range.
