Anyone know where I can get a low-pass crossover for a 100w, 8ohm sub that
cuts in about 80Hz? Maplin QK80B comes close but is too high, and parts
express in the states have exactly this he

or line level ones like these would be ok, too...

The last 2 links were for car audio equipment, but should be ok for normal
hifi(?) I'm powering a passive sub with an old (80s) reciever wit hit's
line-in connected to my main amp mono pre-out.
