Trikos, prettty cool ! love all the DIY aspects of the system . Especially the cavity with the built in Hemholtz resonator . I take it you did all the work yourself . It must have been a pain in the ass stretching all that material over the wall frame . Oh, I do have a question on the center spks. . Are they going to be in sync with the two different distances to your listening position or were you able to synch them somehow .
I utilize a pair of spks. for my center channel as well and have found that by tweaking their position you can create a virtual spk. that comes right off the center of the screen . I plan on mounting the center pair on the left and right hand side of my screen . Just waiting on the mounts .
Have you calibrated the HS-51 with your computer yet . If so could you tell any improvement . I have not had the right setup to try it yet but hope to once I have upgraded to a decent computer . Well, I am starting to rant on and on so......speak at you later .
