OK, this thread is about SVS, you can stop reading if you don't like SVS threads OK, for those that are still here: I started getting into movies in about 1991, when I moved to Atlanta. I had a Yamaha Prologic processor(still do) and watched movies quite happily on VHS(the horror). Then I moved to Cleveland and found a place that used to rent Laserdiscs. By this time I had Paradigm phantom fronts, an Altec Lansing center(THX certified). I found a great deal on the internet for the sub companion to the Altec Lansing--the 75lb sub that went along with the THX system. Imagine a THX sub in an apt. The neighbors weren't too happy. We finally moved to our current location in about 1997 and bought a home. Once my job had some stability, I started upgrading my system. We ended up with an Onkyo receiver(989), a DVD player, PSB speakers(Goldi's in front, Image 10s back surr) Altec Lansing THX surr(side surr) and a Atl. Tech center. Despite the mishmash of speakers, every thing sounds good. I still had only one sub, the Altec. Around 2000, I saw a great deal on a Citation 7.4 passive sub. Despite adding this(and a Cinepro 3K6III), I got the feeling that there was more bass to be had(I had just seen Fantasia 2000 at the Luxor Imax). Around that time there was a new internet-only sub manufacturer the founders of which had helped a lot of people get better bass. I ordered a CS 16-46(order #7) and was very happy with it. It went deeper than either sub that I had and all of them together worked well in my large room(5500+cu.ft.). There was a large peak at 40Hz in my room and I got a parametric eq but felt that the Altec was not pulling its own weight and sold it on ebay. I was down to 2 subs but the performance was better. I got an email from Tom V asking if I would like to be a beta-tester for their new improved driver. I thought about it for about a micro-second and said yes. Once I made the driver switch I noticed the same tightness but more SPL capability. Still there were certain scenes that managed to bottom out the sub(beginning of Toy Story II). I had one spare channel left on the Cinepro but there really was no place I could put the third sub. That changed recently becuase now we are going FP with an acoustically transparant wall. The subs will be behind the screen. I corresponded with Tom V about which would be better for me--the PC Ultra or the CS Ultra. Characteristic of the company philosophy, he didn't try to pitch the higher priced product and told me that since I already had a spare channel, I should go with the passive sub. This despite me telling him that I was afraid of overloading the Cinepro(not to worry, he told me). I received the Ultra about 3 weeks ago and have had it in my system since. Adding the Ultra(tuned to 16Hz with the port plug) I haven't been able to bottom out my subs with any scene. I don't have the Finding Nemo DVD but the Titan AE sub-killer DVD doesn't faze the subs. Neither does Toy Story II, Underworld, etc... I won't discuss "fast" bass but I recently added DVD-Audio capability along with SACD. I really like listening to music with the SVS subs. Properly calibrated(I don't set them higher than the rest of the channels, movies or music) they sound great with music. My kids(11 and 8) loved the system before but now they say they don't want to see movies at our sucky local theater anymore. Another thing that I really like is that they are fairly lightweight and can be moved fairly easily. My wife doesn't mind their looks and will mind them even less once they are behind the ATW and will be hidden. If you've made it this far, thanks for reading. Bottom line: great product, great price(but you already knew that). What makes me want to keep buying from SVS however, is the people that deal with customers and their service.
