Re: The Audiophoolery Thread.
I have been having a recent discussion on the Linkwitz forum regarding someone who wants to extend the bass EQ of the LX521.4 (these are open baffle) to 20Hz instead of the design 30Hz. I pointed out to him that the lowest note on a bass guitar or double bass is 41Hz. You only ever need lower than that if you listen to music with a synth bass line that goes lower, or movies. In which case a subwoofer crossed over at maybe 50Hz might be desirable, rather than pushing the excursion limit on the open baffle drivers unnecessarily.
Of course there is also organ music, but any half way affordable loudspeaker cannot move enough air to reproduce low organ pedal notes realistically.
While I'm on this topic, it is next to impossible to reproduce the volume of an orchestra in full flight. A single trombone at 1 metre can generate 135dB when the player is giving it full beans, with a full orchestra capable of >120dB at typical audience position.
