Eminence Swamp Thang-16 Guitar / Bass Speakers 16 Ohm

Eminence Swamp Thang 12" 150/16 Ohm — Thick American Tone for Heavy Players

The Eminence Swamp Thang 12" 150/16 Ohm is a 12-inch lead/rhythm guitar speaker from the Patriots series, built around an aggressive bottom end and slow break-up. Designed with heavier players in mind, it delivers the thick, chunky tone and long sustain that drop-tune and 7-string guitarists rely on. This model is voiced for very American-flavored blues, rock, and jazz tones. Its 16 Ω impedance and 150 W power rating make it a direct fit for many existing 4×12, 2×12, and 1×12 cabinets.

What Sets the Swamp Thang Apart

What makes this driver stand out is the unusually heavy 59 oz ferrite magnet paired with a 2" copper voice coil on a polyimide former — giving the cone real mass and the motor serious thermal headroom. The result is a slow break-up mode and an aggressive low-end shape that holds together even when the guitar is tuned down to A or lower.

Power Handling and Impedance

Power handling and impedance decide whether a speaker will physically and electrically match an existing cabinet.

• Power Rating: 150 W — handles the output of most 50–100 W tube amps with headroom.
• Nominal impedance of 16 Ω ensures compatibility with both vintage and modern cabinet outputs.

Frequency Response and Sensitivity

Eminence specifies a 70 Hz to 5.1 kHz usable range with a 113 Hz resonance, focused on the guitar's fundamental and lower harmonic content.

• Usable Frequency Range: 70 Hz – 5.1 kHz — emphasizes low fundamentals and growl.
• Sensitivity of 102.3 dB confirms that this high-efficiency design projects loudly even from low-wattage amps.

Mounting Dimensions and Build Materials

The Swamp Thang uses standard 12" frame dimensions with a pressed steel basket, paper cone, paper edge, and Zurette dust cap.

• Overall Diameter: 305.6 mm — fits standard 12" cutouts.
• Baffle hole diameter of 281.2 mm matches common 11" cutouts for direct drop-in installation.
• Depth: 132.1 mm — fits closed-back and open-back 12" enclosures.
