Dealing with an amp without low/high pass filters

[cybasoul]

I've got an integrated amp that has preouts which I use for the subwoofer. However the amp doesn't have a high pass filter to limit the main's low frequency response. What can I do to limit my speaker to 80hz or even 60hz?

I came across this "80 Hz High Pass 8 Ohm Crossover" http://www.parts-express.com/80-hz-high-pass-8-ohm-crossover--266-458
1 - Would this work?
2 - If yes, can I get this locally?
3 - What's the best solution?

Help would be appreciated.
