Wow it's so cool when everyone offers such great insight/advise. Keep in mind that the bass lift most rooms provide is not linear. It's probably your speaker that has failed you. If it's only one channel, reverse speakers to confirm the (1) speaker is the culprit. If not work your way back by reversing the the cable left to right and right to left, one by one from end to source. Eventually you will find the culprit. My guess it will be sooner rather than later. If it effects both channels you will need to find replacement gear and substitute end to source (try changing sources at the preamp first ) or have each piece bench checked. Good luck.
40hz ratings/speaker response
Hi, as a neophyte to the technical end of this wonderful addiction, I am curious. If a speaker's frequency response capability is rated to say 40hz or above, what happens to that sound that was recorder that falls below that range? Say for instance the lower octaves on an accoustic piano, or a cello, electric bass etc? And again, what happens to a speaker, with the same rating, if the volume is "pushed" to hear and feel music that has a lower range?
