i hhave been looking at these y splitters for subs, as in my sub manual it doesn't really say which input to plug a lfe signal into. i decided that i would try a splitter and see what difference it would make - cor, i wasn't half missing out on the lfe action! the sub is now going ballistic wheras before it was a little bit reluctant! i will have to re-set it up but for £25 the qed sub spliiter has worked wonders for me. thought i would share this as i know subs are probably the hardset speaker in a setup to get right and this could well help
