A sub was not on my original plan when I began the HT project. I bought a Denon 3803, Monitor Audio Silver S8's and Monitor Audio LCR ( current Infinity's for surround ) and figured I "might" buy a sub sometime down the line. Didn’t think I would need it! After reading many post on this forum and “strong” advice from a friend I bit the bullet and purchased a Velodyne HGS-15. Last night with the HGS-15 hooked up I watched Star Wars AOTC. “ HOLY @%*! “ I spent to first 5 minutes speechless and in shock and the next 30 minutes scared that my home was falling apart. The last time I felt the room shake like that was the 1993 Northridge earthquake. Absolutely amazed at the overall experience the sub brings to the system. I spent the last 8 hours at work smiling and laughing to myself at the thought. Borrow……beg…….steal !!!!!!!!!!!!!! Whatever it takes…………”YOU MUST HAVE A SUB !!!!!!
