It doesn't surprise me at all that both PB13's were operating fine. The PB13 amp menu can be pretty daunting for inexperienced users. There are a lot of different settings and sub-menus. This was most likely a case of user error from the sub and possibly also from the receiver. Very little output is a symptom of using the speakers set to large, but I think that was previously covered. My little PB-1000 will pound hard if I want it to. The JTR subs should be a lot more simple and easier to set up.
