Incorporating Sub into two channel stereo


I am interested in adding a powered subwoofer to my two channel stereo system which includes Krell KAV 250a and 250p with B&W 804 matrix speakers. I have no idea how to do this as there is no subwoofer output on either the amp or preamp. Any help would be much appreciated.

Thank you.

Running your speakers fullrange, and then trying to blend in a subwoofer with them, depends on a few things.

Blending a subwoofer into the system, without use of a hi-pass filter on the mains, only works...sometimes.

Many speakers have 10-15db peaks at "just above" the point where roll off begins...you will never get a good blend with these types...you have to use a hi-pass filter with these.

Ported systems...along with, panel types, (Apogee, Maggie come to mind)...probably Soundlabs?...although I have never measured a pair of Soundlabs.
