What a day, I got the VS 18.1 subs. First I had to get the monsters in the house and down stairs. These things are 40 X 22 X 22 inches and with the boxes, a little larger. Luckily, I made some subwoofer risers with wheels to make the task easier. And, it was still a big job. I now have 4 subs in the HT. I kown I am mixing 2 sealed sub with 2 vented sub, lol. The vented subs were on closeout and they are no longer making the sealed SS 18.2's. Next was running new wire and making all the tricky Neutrik connection and amp settings. This part is eay to messup using a pro amp.
I wondered if I would realize a large benefit going from two to four subs. The answer is a huge YES!. The headroom allows for increased dynamic response and range. They took a lot of work to get them to play well together but, I think I did it! The DSP on the Behringer amps went a long way in the integration process. All four subs are at a different distance(room constrints) so getting the phasing a timing correct was a monster.
I have demoed a few movie clips and did some extensive music listening. The bass is so tight and articulate using four subs. Movie dynamic and the low end is off the hook even in my concrete bunker, lol. The ears need rest as well as the back. I only took a few pic's and most of them look terrible so, I only have two, lol. I guess you don't do anythig right when you are tired.
PS I painted the bottom of the sub risers black.
