Credence subwoofer performance curve

Home and car system.

This system is very similar to the 1.0 cu. ft. ported system, using our high power 12RPSLD4, radial roll, cast frame woofer, but it uses a little larger 1.5 cu. ft. enclosure for even deeper bass, down to 20 Hz in-car.  You may need to use an external port, as the port requirement is substantial:  3” I.D. x 18 5/16” long, or better, 4” I.D. x 33 1/2” long.  If you can fit that in, this is a great(!) system for the low-bass lover, in a modest size box.  It is also excellent for home use! For full power handling, use a sharp High Pass filter at 20Hz.
