Current set up is: Marantz SR4300 Amp - preouts into Arcam to power the two front speakers - BW 601S2, Centre speaker is BW LCR60 S3, Rears are Mission M71i. Just bought and added an sub, have to admit I hadn't heard it first as none of the Hi Fi shops stock it near me so I wen't from various recommendations, the MJ Acoustics Reference 100. The sub is set up as follows: Use the lo input right channel to connect to the amp. Low level gain is set to 11 o'clock Frequency Contour 120 Hz (LFE) Phase set to 90 Question is am I doing something wrong or going deaf - for £350 I'm a little unimpressed with the addition to the overall sound, I either don't really 'feel' or 'hear' the base or when I turn the gain up to 1 o'clock I 'hear' the bass but it doesn't seem to fit into the sound i.e. I can hear it too much but still can't really feel anything - were my expectations too high? p.s. I know I was a fool to not listern to it first but I thought with that many good reviews in mags and forums I couldn't go wrong!
