I have just bought myself a new REL Q150E Mk2 subwoofer. The store I bought it from has given me advice but I am not sure whether they are right. They told me to connect to the +12DB input on the subwoofer and choose slam rather than depth. I found it sounded better on the 0DB input on the subwoofer. What is the correct setup? At the moment I have set my PMC TB2s to large as well as my centre speaker (which is huge). Is it better to set all my speakers to small and route all the bass to the subwoofer or will this annoy the neighbours?
