The AQ is not too good for sq eh? I am looking at those for a daily system and want to know how far can you push the HDC3 15 power wise for a single sub safely? I also wonder how does it compare SQ wise to say a Incriminator Death penalty 18? I only ask because I have a brother in law with one of these so I know what it sounds like. Would it be better or worse in the SQ department?
