I have a paradigm PS1000 which has sub-sat phase alignment, cut-off frequency and level controls. The manual suggests playing some music and setting the controls based on the instructions therein. However, will this then have an adverse effect when using the MCACC on the AX5? Basically, what is the best way to set the sub up? Should I just set all controls to mid and let the amp sort it out or should I set the sub up first using a simple stereo source and then run MCACC? Alternatively, should I set some of the settings based on my other speakers and the amp specifications - e.g. the cut-off frequency? Currently I don't think I'm getting the best from the sub as the amp has decided it's 3.7 metres away (when in fact it is only 1.5) and set the channel level to -9dB.
