Today I finally got my Tannoy MxSUB10 after months of waiting for it to arrive. Got home pluged it into my amp using single phono cable. On my Yamaha DSPa-595a i changed the bass setting to SW, but the sub would not would work. I then changed it to BOTH and it started to work. Putting on Gladiator first i was shocked to hear how much better the sound was. I could feel every vibration on the floor. However i am a bit worried about the settings. Is it suppose to only work on BOTH mode? Surely it should be set to SW and work. My speakers are set to large as they are large speakers. Can anyone help with this? Secondly I am completely stuck with this Crossover stuff. I cant seem to hear much difference if i mess around with the cross over. WHAT DOES THIS MEAN???? Also what should i have the DD and DTS LFE on? DD goes from -20 - 0db and DTS is -10 to +10db? Can anybody give me any furthur help with setting it up correctly. Apart from that the sub sounds amazing and i recommend everyone get one if your sub budget is only £250. The only reason i am asking the above questions is because i am not sure if i set it up correctly. Thanks for the help!
