Ez, im after an active subwoofer to go along with my KRK rokit RP5's to give me that extra bit of punch. Looked at the krk one but £300 is abit out of budget. Im looking to spend £200 tops but if i can spend less and still get good quality that would be great. These are the best i've found, which is best?! http://www.htfr.com/more-info/MR347397 http://www.hifi-tower.co.uk/default.aspx?TY=2&ST=1&IT=2029&CT=28& http://www.hifi-tower.co.uk/PA_SYST...A_Subwoofer_600W_Bass_Speaker_i142_1486_0.htm http://www.djsuperstore.co.uk/=froo...ccessories/366689-ikey-audio-m10su-active-sub Can anyone find any better? Cheers!
