I was curious if anyone knew which design would sound better and be easier to adjust with a pair of subwoofers (GR non servo sealed 12") Obviously the Transmission Line design is a better choice if one is just listening to 2.0 stereo and this was my original choice, however since I already have 2 subwoofers I could make better use of what I have. I eventually would like to get a servo or 2 and pair them up into I unit by attaching them together. This wouldn't be practical with the towers, however if it is easier to blend the T.L. With the subs, I would just put them along side of each other. Thanks, Jim
