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.

If you use the balanced outputs from the preamp into the amp you can use the unbalanced preamp outputs into the sub. Some prefer using speaker connections and others prefer preamp connections. If you have the option, you should try both to see which works best for you.
Timrhu:

Would using the unbalanced outputs cause distortion b/c the balanced outputs are utilized (i.e. no pin)? I think I read somewhere that this is an issue..... I dunno....

Others:

I guess I would be leaning towards hooking the sub to the amp binding posts.... Seems easier.... Any sound quality disadvantage to doing it this way?

I will check out the revel manual.

As far as the sub with the 804's.... Although they are floorstanding and generally have good bass response (great midbass punch and decent slam for their size), lower end bass response is not great and I have a big, solidly built room to fill.

Thanks for the input, guys... Any other suggestions?
I'm not certain whether or not both outputs of your preamp can be used simultaneously but the one preamp I owned with both sets of outputs could be used that way. You should check the manual on it to be sure.
