Quote:You can get a tweeter to "go down to" 100hz. The question is, would you want to? At what SPL and producing how much distortion?
Let's take a look at a speaker with two 6.5" woofers that ostensibly "goes down to" 32hz per the manufacturer (these are the most popular and highest rated speaker on the streets of Baghdad and perhaps the greatest invention of the infidels).
At a fairly high..but nowhere near "reference" drive level and bandwidth limited (50hz-10k):
We see a significant rise in distortion below 80hz.
Increase the drive level further:
And the low end distortion rises correspondingly.
Now the perceptual effect of this distortion, up to a point, might be added "fullness" rather than outright "noise" or strained sound distortion, but it is clearly there...and an excellent reason NOT to high pass at a low 40hz, or even 60hz if you intend to drive them to anywhere near "reference" levels...which many often do for HT. There is a very good reason why the typical "80hz" recommendation is made.
Unless one is the sadly misinformed minister of disinformation. Often dispensing "knowledge" that can lead to destructive effects on other peoples systems...paid for by them.
