American Bass ES Series Shallow 12" Subwoofer Dual 4 Ohm

The American Bass ES Series Shallow 12" Dual 4 Ohm Subwoofer is built for dense, demanding bass in compact vehicles, delivering up to 1500W max (800W RMS) from a slim 4.3" mounting depth, a 65 oz magnet, and a 2.5" dual voice coil.

• RMS Power: 800W — represents the continuous power the driver is designed to handle; this translates to sustained bass performance without thermal stress under typical music playback.
• Max Power: 1500W — indicates the peak power the woofer can tolerate for brief transients, useful for dynamic bass passages and impact moments in songs.
• Impedance (OHMS): D4 — dual 4-ohm voice coils offer flexible wiring options to tailor impedance for different amplifiers and system layouts.
• Sensitivity: 84 dB — a measure of efficiency; higher values mean more output per watt at a fixed distance, aiding overall system loudness with given amp power.
• Mounting Depth (IN): 4.3 — a shallow mounting profile that enables installation in tight spaces where deeper woofers won’t fit.
• Cutout Size (IN): 10.79 — the required diameter cutout to mount the subwoofer in a panel or enclosure; ensures proper fitment planning.
• Ported Box (FT³): 0.75 — recommended internal volume for a ported enclosure, guiding enclosure design to achieve bass efficiency and tuning goals.
• Magnet Size (OZ): 65 — a substantial magnet that contributes to motor strength and the ability to control cone motion under higher power levels.
• Voice Coil Size: 2.5 — a large-diameter voice coil increasing surface area for heat dissipation and thermal handling at higher power.
• Basket Type: CAST — a rigid casting provides mechanical strength and helps reduce mechanical distortion for cleaner bass.
• Recommended Amp (Pair): PH 4000 — a paired-woofer amplifier recommendation to ensure adequate power delivery and headroom for a two-sub system.

In real-world builds, this woofer excels in compact enclosures and shallow-trunk or under-seat installations where space is at a premium. The combination of a shallow depth, a 0.75 ft³ ported target, and dual 4-ohm coils provides flexible wiring and solid bass control, making it a strong choice for a two-sub setup paired with a capable amplifier like the PH 4000.
