    This may sound crazy, but I have to ask it.
    First of all - my audio setup consists of a 5 speaker DD 5.1 & DTS system. No subwoofer right now.
    Okay - Here is the crazy part. I have a pair of speakers (seperate from the ht setup) with 15" woofers in them. Is it *possible* to run the subwoofer out of my DD/DTS receiver into a secondary stereo receiver (with a mono -> stereo RCA adapter) and run the two speakers as "low end only" speakers? Or...is this a big no-no?
    - Chris

    will it work? yes.
    will you get true sub bass? probably not.
    the 15's in those enclosures were probably woofers, not subs in the first place, designed to produce bass and not sub bass. enclosure tuning comes into play there also.
    OTOH, you have the stuff so give it a shot. probably better than nothing. if it sounds better to you, its better to you [​IMG]. get out your radio shack SPL meter (you have one, right? [​IMG] ) and run some test tones through them once you have them running, see what your actually getting.

    I tried this once with a pair of old fisher 3 ways.I disconnected the mids and tweeters and just ran the 15's.THey simply could not handle most of the lfe info from most dvds I tried.They sounded much better running them large off of the "b" speaker output.

    What brand of speakers?
    I have done this same thing with good results. Actually they were Fisher 15"ers. I did build new boxes that were tuned much lower than the originals and much heavier construction!
    I have ran these subs for 5 years now after having ran them for 6 years prior in the Fisher boxes. In a few weeks I will be firing up my new theater and will use the Fishers until I can afford better raw speakers(may look at the Dayton 15"). And my 15"ers handle themselves better than my brothers Definite 18"er, although the Def 18 will go a bit lower!
    Here is a couple links to what they look like now:
