Credence subwoofer performance curve

 

This system uses our new high power12RPSLD4, cast frame woofer in a 1.0 cu. ft. enclosure for smooth, powerful, yet effortless low bass. An external port is most likely needed, as the port requirement is 3” I.D. x 19.2” long, or, better, 4” I.D. x 35” long.(!) (Tuning freq. = 30 Hz.)  But, if you can work that in, or out, this system puts out a lot of solid, clean bass, down to under 25Hz (in-car), in a very handy, small package. Below that, use a sharp High Pass filter at 23 Hz, for good power handling.
