    Recently tested my speaker set up on a THX audio test. Towards the end of the decrease in the pitch tone the subwoofer sound disappears well before the test ends.

    Now I've got the Mission 6-cinema pack so am aware that the Sub isn't great. owever I've also got the Sony STRDB940 which I find difficult to navigate around.

    I've messed around with crossover frequency on the sub. Had a quick look at the amp, but if I'm honest, don't quite understand it all.

    Anyone got any ideas?

    Should I get a different sub?

    Am I stupid? <img src="confused.gif" border="0">

    I assume you have connected the sub via line level (RCA/phono cable) only which is sufficient for AV use.<br />Therefore the amp will take care of the bass management and the crossover on the sub can be set to maximum (e.g. 150Hz or whatever applies in your case).<br />However the problem seems to be the low end, therefore fiddling with the crossovers (either at the sub or amp) will not help, I therefore have to assume the sub just can't get that low.

    I think the sub that you have got with mission system only goes down to 36Hz. The THX audio test actually goes all the way down to 20Hz (I think), as per the THX specs, so your sub is not able to produce the last 16Hz. So if you want to get that real low bass out of your DVD's you are going to have to get a different sub.
