Powerbass XL-1240T 12" Shallow Mount Subwoofer

The Powerbass XL-1240T is a 12-inch shallow-mount subwoofer engineered to deliver 400W RMS in a compact sealed enclosure, ideal for tight automotive spaces where a standard 12" woofer won't fit. Its single-piece injection-molded flat cone, a 140 oz magnet, and a poly/glass fiber basket preserve solid bass control in a shallow footprint.

• Power Handling: 400 Watts RMS / 800 Watts Max — provides headroom for dynamic bass peaks without clipping in a sealed enclosure.
• Nominal Impedance: 4 Ohms — compatible with amps designed for 4-ohm loads, allowing flexible power delivery.
• Mounting Depth: 3.8" — shallow profile that fits in tight dashboards or under seats while preserving space.
• Cutout Diameter: 11" (281mm) — ensures a proper fit on standard circular openings common in vehicle enclosures.
• Cone Design: Proprietary Single Piece Injection Molded Flat Cone — yields a stiff, uniform cone for consistent bass response and reduced distortion.
• Basket: Proprietary Composite Poly/Glass Fiber Basket — rigid frame that supports high excursion and minimizes unwanted resonances.
• Voice Coil: 2" Vented KSV Voice Coil Former — improved heat dissipation and power handling during sustained bass.
• Magnet Size: 140 oz — a robust motor helps control cone movement under high power.
• Sensitivity: 89 dB (1W/1M) — efficiency rating indicating how loud the sub will appear per watt in close listening, useful for system gain planning.
• Frequency Range: 33 Hz - 450 Hz — notes the lower and upper limits of the driver's output, covering deep bass up to mid-bass notes.
• Voice Coil Size: 2" — larger coil supports higher power handling and better heat management.
• Dust Cap: PBX logo dust cap — branding detail present on the front.

In a compact sealed build, this subwoofer maintains controlled, impactful bass without requiring a large enclosure. It suits discerning listeners upgrading space-limited vehicles or custom installs where a traditional 12" driver wouldn't fit, delivering reliable power handling, solid bass extension, and a durable, rigid structure ready for daily demanding use.
