1265MX | Bumper Subwoofer Pro Speaker 12 Inch
Designed with SPL in mind and plenty of travel the MX Series speakers are primarily used in car audio application providing deep bass frequencies. However, many home audio enthuses love to use it in DYI home theater projects. These speakers are designed with 1” diameter heavy black foam surround and laminated cone body. The vented backplate piece for heat dissipation and 0.400” thick top plate is to maximize the magnetic efficiency and energy. The MX series is very user-friendly and works well with both sealed and ported enclosures.

Warning! Loudspeakers can produce sound levels that can permanently damage hearing. The threshold of pain is always an indicator that the sound level is too loud. To establish a safe level of sound start your volume control at a low setting and slowly increase the sound level until you can hear it comfortably and clearly without distortion.
