Adding a subwoofer to a 2 channel amp

I have a Rotel RB-1050 amp, a Rotel RC-972 pre-amp, and a pair of Fostex 126e Zigmahornet speakers I built. The original speaker design used Fostex 103e drivers that reportedly resulted in poor bass response. The 126e's were suggested to fill out the bass. The resulting bass I have obtained I rate at about a 6-7 on a 10 point scale.
Would adding a subwoofer be a good idea and if so how would I do this given the Rotel amp is a two channel amp? Thanks for any suggestions I am a newbie.

I use the RC-972 pre-amp with a Carver M1.0t Main amp.
The speakers are Maneplaners, MMGs, coupled with an HSU research powered sub. The sub has a built in adjustable crossover, phasing switch and volume control. The RC-972 pre-amp has two outputs. I just hook the main to one set and the sub to the other. The system is easy to calibrate and sounds excellant.
