Ok guys here's my snag? In the last couple of months I've completely revamped my home cinema setup with all new gear. (see my sig for full specs) I bought the M70AS sub to go with the rest of my M70 speakers and it does seem to give a lot of LFE with its 10" driver in my 13'X12' flat. However, I here people saying that a good sub should cost around £500 (mine cost £200) and I'm thinking now of upgrading again to to M5AS. I'm possibly falling into a trap here in that I'm thinking I've bought excellent speakers but seen my self short on the sub, when in actual fact I don't think it sounds that bad. Do you think that I would find any significant improvements to my system by getting the M5AS. My wife would probably go mad, but hopefully get over it eventually!
