That's quite scary.
Ya I did notice that most Yamaha speakers are -10db. Even studio monitors are -10db too. But I think that the Yamaha MSR100 speakers mean that at 55hz its -10db. Even other studio monitors like the MSP10 are 40hz to 40kHz -10db. So of cource that means that at 40hz its -10db. Other monitors like the MSP3 are even -10db at 65hz too.
