Ok I jumped onto the SVS bandwagon a while back to see what all the fuss was about. I was a fairly happy owner of a Velodyne CHT15 before making the switch (I have also had quite a number of Rel ST Subs in the past) and some will accuse me of jumping on the latest thing and hyping it just for the benefit of Tom and Ian. I will tell you now that any such comments or suggestions are rubbish, If I don't like something, I will tell all I'm not shy. And I am still undecided on the SVS thats for sure. I picked my sub up Last Saturday from Liams and he came with me back to my Cinema Room to help carry and set up the sub. The sub was placed in the alcove where the Velo sat firing out at the seating position. Obviously the SVS in a downward firing sub, but Tom and SVS recommend corner positioning. I quickly set it up using an spl meter and the tag tones, checking the other speakers as we went. Then put on Chp 4 of Moulin Rouge ("welcome to the moulin rouge") and sat back. "Wheres me bass gone!" I said looking at Liam. "Mmmm" said Liam. For whatever reason the bass had gone, especially in the mid band frequencies. So we put on Avia, and my worst fears were realised, I had a major dip from roughly 90hz down to 40hz, by about 9-11db. We moved the sub around, did the old walking around till you find the best spot, but the sub never produced any real spl in any location. Finally before Liam walked out the door, after i told him that a contract would indeed be taken out on him and Ian (Cheeky begger said I would know the right people as well ) I then found a placement where the bass returned in some volume, it was right behind the seating position. I continued to play around, and Liam went home to play with his. So after a week of use, how do I rate the SVS? It goes low, it is fast and accurate with music, but it also struggles with certain material. The dts "digital experience" intro makes it sound over loaded and bloaty at -12db. (the velo did this but not as bad). The intro to AOTC is just too much for it as well, and this is at normal sensible volumes -15db. It also doesn't seem to presurise the room in the right way or with any real spl. Move around the room and it disapears altogether. This is worring as Liams sounded rich and full balanced in his much larger room. With music this Sub is a dream to use, it is unnoticeable, yet switch it off and all the feeling goes from the track. Yet with movies it is very hit and miss. Maybe the velo was at fault, maybe what i was actually getting from it was just room induced boom, which made me think it was full bodied? I don't know, but in my room the spl levels were far higher than the SVS and the bass was fuller. What I really need to do is plot the room, but my skills with excel leave a lot to be desired, infact i just looked at it and thought ******** with this. When the shop downstairs closes tonight i will make my measurements, but i will need someone to plot the graph for me, any takers? Once i see what is happening, I then need to look carefully at how I am going to improve the dustbins performance. I know my room is not perfect and that some kind of EQ or room acoustical treatment is needed. I might have to pick Liam up and bring him over with his BFD and ply him with Beer. At this moment in time, the jury is well and truely out. It works wonders with some material, and doesn't with others. That to me suggests a room problem, but i don't know where the spl is going as it never manages to fill the room, and to get the best performance I am literally sitting on top of the thing. Advice always greatly recieved.
