Hi
i have just received a peq-2200 ( ultra q ) today which i bought of ebay too,
it has the same variable low and high cut that the 3102 has or very similar, it does a good job and cuts all sub bass under the frequency desired so would image will help no end if you are trying to protect you sub (s).
The eqs are too bad ethier.
Its not as clean sounding as a bfd but good anyhow.

I also have a couple of cx-3400 crossovers which cut at 25 Hz, they work well also and still leave plenty of decent sounding bass.
