I am currently trying out using my old pair of Spica TC60 as a sub driven by a Parasound 1000A power amp. The active crossover is a Paradigm X-20 and cutoff is set at 100Hz. Currently, connection is via the external terminals. Do you think I should connect directly to the woofer terminals bypassing the passive crossover inside the box ? Will I get a lower and better bass response ?
Follow Ups:
It won't be lower but it might sound better seeing you're bypassing the inductor.I had a pair of these. I think you can find a more suitable speaker to use as a sub. These are really compressed dynamically and don't perform very well in the bass let alone the sub bass. Can you say MIA?

Thanks Mike,What is your recommendation if I were to change the drivers ?
Don't destroy your TC-60's! If you aren't aware it's a near classic speaker and will fetch a reasonable price on the used market.
The box is too small for realistic bass. They are a neat speaker though, really image nice with nice mids and highs.I recommend buying/building a larger box 3 cu ft or bigger and using at least a 12" woofer if you want to get down to the depths of true subwoofing. The possibilities are endless. A nice looking driver is the Titanac at www.partsexpress.com. It is a 12" designed to work in a small box and still go low without bottoming out. The specs are ideal.
