    There was an article in Audio (about May, 1983) which had designs 
    for three home-built subwoofers based on JBL speakers.  There
    was also a design for an active crossover for subwoofers in a 
    companion article.  The crossover used about 7 op-amps and looked
    pretty easy to wire up.   The authors claimed it did not degrade 
    the audio information measurably.  It could be driven by either
    a stereo or mono amp.
