Sub best at high crossover?

O holter, this thread is getting silly. You've received rational advice and if it feels good do it advice. What is it you're looking for? I personally use a pair of Velodyne HGS-15s with an SMS-1 bass manager in a medium size room, so my experience is not the same as yours. I like to be unaware of the sub or any other speaker as the source of music. If it's an authoritative answer you seek, why not just go with the THX recommended 80 Hz; if it's an explanation for your perception, why not engage in magical thinking as so many other audiophiles do?

Vicdamone, IIRC it used to be common practice to use the 3 dB down point when quoting frequency response limits. But that may no longer be the practice and it may never have been universal. Frequency response tends to drop like a rock below the 3 db down point.
