Designed with heavier players in mind, the Swamp Thang provides a thick and chunky tone with loads of sustain. The awesome bottom end will hold up to even the most demanding drop-tune or 7 string players. Key specifications include 150 W power handling, 8 Ω nominal impedance, 70 Hz - 4 kHz usable frequency range, 102 dB sensitivity.

Its construction features a ferrite magnet, a paper cone, a 2", 50 mm voice coil, supporting reliable performance in compatible cabinets and amplifiers. Use it for amplifier upgrades, custom cabinet projects, tonal experimentation, or restoring a working rig with a speaker selected for its musical response. Before installation, confirm the amplifier's impedance requirement, available mounting depth, cabinet cutout, and power compatibility. For best results, choose an enclosure and amplifier pairing appropriate for the published specifications and the desired playing style.
