Its single 4-ohm voice coil makes it a straightforward choice for an amplifier that is stable at a 4-ohm speaker load. It is intended for customers building a compact daily-driver bass system or replacing an existing 12-inch subwoofer.\u003c\/p\u003e\u003cp\u003eRated for 300 watts RMS and 600 watts peak power, the SRX1240V is suited to properly matched amplification rather than oversized power. Its 85 dB sensitivity and 12-inch cone support bass reproduction in an enclosure designed for the driver. The single-voice-coil layout also keeps wiring simple when using one subwoofer.\u003c\/p\u003e\u003cp\u003eA polypropylene cone and rubber surround form the moving assembly, combining a durable cone material with a flexible outer suspension. The progressive poly cotton spider is designed to help keep cone movement controlled. Together, these components support consistent operation in everyday vehicle audio use.\u003c\/p\u003e\u003cp\u003eMemphis uses an anodized aluminum voice coil former and a 30-ounce magnet in this model. The subwoofer also has 12 AWG compression terminals for secure connection of appropriately sized speaker wire. Its stamped steel frame provides the mounting structure for installation in a compatible enclosure.\u003c\/p\u003e\u003cp\u003eThe SRX1240V is optimized for sealed or ported enclosures, allowing the enclosure choice to be matched to available space and listening preferences. Memphis lists a 1.0 cubic-foot sealed enclosure volume and a 2.2 cubic-foot ported enclosure volume. Verify enclosure dimensions, amplifier compatibility, and mounting clearance before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 4-Ohm Voice Coil:\u003c\/strong\u003e Simplifies amplifier matching for a single-subwoofer installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300W RMS Handling:\u003c\/strong\u003e Supports use with a properly matched 4-ohm amplifier channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Provides a durable cone surface for automotive bass duty.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRubber Surround:\u003c\/strong\u003e Supports cone travel while helping protect the moving assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgressive Poly Cotton Spider:\u003c\/strong\u003e Helps maintain controlled cone motion during operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Or Ported Compatibility:\u003c\/strong\u003e Offers enclosure flexibility for different installation goals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SRX1240V uses a stamped steel frame, polypropylene cone, rubber surround, progressive poly cotton spider, anodized aluminum voice coil former, and 30-ounce magnet.
