Yeah no one is entertaining that because it's a really stupid take. It just shows you don't know much about loudspeaker manufacturing, driver differences, cabinet differences, etc... The tweeter is different, the mid is different, the coaxial drivers loading is completely different with better termination to the cabinet. The woofer is different and looks to be a higher quality (cast basket vs pressed). Distortion is spec'd lower on the SM-5, the cabinet is likely much thicker mdf with better bracing and dampening. You seem to be asking why any speaker would ever cost more than the in-5, as if that speaker doesn't have any issues.
