Hi everyone! As you can see below I currently own a REL Strata III but have started to notice it run out of steam lately. On some movie sequences the set safe kicks in and reduces the output. So Im looking for a new sub. I have my kit in a dedicated room so looks arnt an issue. The room measures 5m by 3.5m and is an upstairs room. I have all my speakers and sub on concrete carpet covered slabs to reduce transmission into the floor as well as sound reduction materials under my carpet. I have read with interest some of the very positive feedback on SVS, but I'm not sure which model would be right? I like the idea of either the PC Ultra or maybe the PB2 Plus. Im a bit worried however that the PB2 Plus would be a bit too much for my room. I prefer a very tight and accurate sound with real impact over ultimate deep frequency response. I cant stand resonance or bass boom, although I do have TMREQ on my side to help eliminate any such problems. Any suggestions or personal experiences would be great.
