Normally, if someone thinks that the LP and/or LP2 aren't bass-heavy, I'd say that they are probably married to a subwoofer.He did mention that he bought them used, and his picture does show that they have been well used, so its possible. But I really hope that they are not damaged and are ok, I hate to see it when people lose money on something.
In this case, however, I think his headphone/drivers may be damaged after all.
