car Heater 25

This is a super upgrade replacement woofer for vintage home, pro or semi-pro loudspeaker systems such as the AT-12, D-7, MX-400 and any others that used the classic red foam rolled edge style cone for high efficiency and deep bass. This woofer is designed, engineered and fabricated here in the US to replicate original factory performance with approximately 50% greater power handling. All parts are sourced from vendors based in The United States. The voice coil is also 100% machined here in the US to .001 inch tolerances. The efficiency is very high and bass notes are projected with an incredibly strong punch. Impedances available are 4 or 8 ohms.
