Credence CS186DV performance curve

If you are looking for a little more bass “bump” with the CS186DV, than the 32 Hz tuned system will give you, and also need less of a port, but still “tons” of power handling and output in a smallish box, here’s the system for you.  Did we say “a little bump”?  Well, actually, it may “bump” you more than you can handle!  Here’s the scoop:  A 6” I.D. port,  24 5/8” long will work; but a 7” I.D. port, 18 5/8” long will be better.  Obviously, the port may have to be mostly external to the box, but still allow for whatever space the port takes up in the box, if any.  Also see the 1.5 cu. ft. box for more port cross-section details.  Finally, for full power handling, use a steep HP filter @ 25 Hz.  We think this is the configuration most buyers will find the most useful, so it is our “recommended” system.  But if you like one of the others better, that’s fine too!
