Hi guys, After the advice here of which sub to buy, (thanks all) I have just taken delivery of a BKXLS200 whick looks wonderful Problem is I can't get it to work! Its operating as expected with the test signal from my VSXAX3 but I can't get it to to do anything with a DVD source. The fronts (tannoy R3s & RC) & rears (Mission M73i's) work perfectly in surround. I've been using the Starwars & the opening sequence of Goldmember (lots of bass) as a test but no sub output at all (even when amp indicates LFE output). I've got the sub connected via a single phono (low level) to the amp (sub) single preout. The amp is taking a digital signal from the DVD. HELP! What am I doing wrong? )))) I've not tried the high level input yet, why this an option for an sub with a built in amp anyway? I must admit, I really am clueless!!
