Hello Danny Thanks for the detailed response I like that ! However beeing a non pro and just a beginner I wonder how important it is to compensate for delays and what is the sounding distortion that results from unajusted lines delays ? I do get some boxiness in female voices and sometimes in male voices , where do I have to look for the problem and correction ? Why dont you have your LS6 and LS9 on your site ? soon I'll be interrested in the LS9 !!! JPH
