All, I Received my 20-39CS+/S1000 Dual Sub package yesterday. In fact, it has now been over 24 hours since I received my electronic goodies and the grin on my face is still ear to ear. I took a day off of work eagerly hoping for early morning delivery but "Brown" did not show up until 2:00pm. All (3) packages arrived at the same time (always a plus) but with some minor damage to one of the sub boxes. I was kind of worried at first but the guys at SVS did a great job at packing so all was OK. Like a kid in a candy store I just could not wait to connect and calibrate. After making all the necessary connections and with trusty SPL and Video Essentials in hand, calibration was a snap. As with a lot of other owners I spoke with, my sub level is running 2dBs hot. 4:00pm With all the setup complete it was time for a demo or two or three...you get the idea. First up was U571 "depth charge" scene. WOW! These things are relentless in there performance. Hard hitting, tight, and quite scary too. Next up were Blade, Dark City, Das Boot, and "The Bass Standard" SW:TPM LD. Whew...that was insane! Note: After playing the demo scenes over and over, the location of the subs eventually ended up in the same location as the old ones (one in each front corner of the room). I tried them in the same corner and they sounded awesome but I felt like I could localize the bass too much. Moving the subs to seperate front corners I felt the bass more evenly and had a harder time figuring out from where it was originating. 6:00pm Time to let the neighbors rest and recover from the onslaught. Me too...need food. 8:00pm Rest over...belly full! Now came the time to put in a title for a full viewing. I wanted something that would give them a firm yet thorough workout....Godzilla came to mind. With the volume level at -12, each and every step 'Zilla' took was an experience in itself. I swear these things are posessed. The bass they produce is like a shockwave hitting you after an explosion! Lights and pictures on the second floor were rattling like you would not believe. Unless, of course, you are a fellow SVS owner. My wife even remarked at how much better they sounded when compared to my old Altec powered subs. Now that is when you know the upgrade was worth it. In closing, I have to say that these are the most accurate sounding subs I have ever heard. I still cannot believe the depths to which they troll with the "port plugs" installed. Truly astounding! Tom, Ron, and all at SVS produce a quality product that delivers in every way. They are one of the few products that actually live up to their billing.
