It appears that I could get a lower response with this system:

if I went with a single 150 midrange woofer instead of 2. It would result in a smaller case and I could tune it to about 50 Hz from my evaluations with WinIsd. What am I missing here?

If you used a box twice as large and tuned it to 50Hz, it would have the same response, but it would also have another 3dB overall output capacity too.

If you want bass response, it's always a good idea to have more than a single 6" woofer. And if you're going to build a monitor to sit on a stand, may as well build a floor standing tower with some extra woofers to ease the load and add dynamic range.

I intend to add another speaker to the side towers, but I would like to keep the center channel small enough that it does not overwhelm the top of the TV.

You'll want to keep the mid and tweet in a vertical line for best horizontal dispersion.

Ya, I hear you. I don't think I can do that, so I guess I will have the "advantage" of confiming a well known theory on speakers for my first time. I assume that the lobe will be wider the closer I have the speakers together.
