My vote would be "yes" to using two sub woofers.
In my previous setup I had a "Y" cable to combine the left and right preamp outputs into a single feed to the sub. That worked well.
But with my latest setup, which is much higher end, my dealer and a number of my audio buddies argued for me to deploy a pair of subs, one for each channel, and I must say, the "visceral" experience is better, especially when listening to classical music, where the double bass sounds might be coming from one channel.
When I was struggling to integrate this pair of subs, at one point I moved them to behind the listening position, and the result was not good. Most of the music coming from the main speakers was well positioned, but the sound stage for the low frequencies was "all over the place", the "sound" coming from the front, but the "feel" coming from behind.
