Having read previous threads about what setting I should have my speakers on (Small or Large) I really would like to get to the bottom of this ever confusing discussion. Most people on here seem to say 'stick with small" it's safer. That's ok but not very precise. I have Paradigm speakers CC170 centre, floor standing front left and right, Paradigm surrounds and single centre back CC100 and NO sub woofer as I can't stand the things.. I decided to send an email to Paradigm themselves and this is the answer I received. Hi Simon, If you do not have a subwoofer in your setup you would want your speakers set as large. You would only want to set your speakers to small if you have a subwoofer. Jamie Z. | Technical Advisor | Paradigm/Anthem Support Team Seems a bit too straightforward to me. I expected a little more information. I have sent another email asking for just that. I understood that if my speakers were set to large they could be damaged by frequency change. I am fairly well up on technical stuff, but frequency's and the other technicalities on speakers does lose me. Anyone with any comments. Most welcome.
