It’s crazy how the most affordable line is the most enjoyable, but I know what you mean. For casual listening the q series might be enough for most of us, but the ceiling is what it is. We’re paying for better cabinets, and parts that give the R and reference line a higher ceiling with wider bandwidth and higher spl with less distortion. Unfortunately the tighter the tolerance the more demanding of source.
There’s another reason…personally I get used to the brain rattling bass coming from my pickup stereo and booming midbass is fun. Klipsch are really fun.
