I have 4 x lsi9 and a lsi C connected with blue jean cables to a NAD T-753. I used a SPL meter and the Avia II to calibrate. My room is about 3500 Ft3.
However, after all of this, the audio through the center channel is not convincing. Sometime we have hard time understanding what's being said in the movies.
1) Is the NAD enough to properly drive my set up (this receiver can handle 4-ohms)? I don't listen to stuuf to loud, generally.
2) Do any of you have experience in using a lsi9 as a center?
3) Is there any way to check is the lsi C is defective?
Lastly, I am deciding on a sub. After reading A LOT in this forum I think I would like a SVS or Velodyne. Budget is about $1200. I really want "A DEEP CLEAN BASS" and not boom boom boom. I think I'll get more out of the sub when listening to music. With Tweeter selling at 50% disciunt I was wondering if getting the Polk DSW 4000R ($1600 retail) was a good idea to do the job.
I look forward to your comments/advice.
