Ah, you were asking about the tunning of the uperbass horn?
That is very simple. You need to make the primary resonance to hit exactly at
the horn’s mouth rate. So, it is it 110Hz horn then make the primary impedance
to peak at 110Hz, there are many ways to measure it by manipulating the size of
the back chamber.
Ok, should I let it go or to be me? Ok, let to be me. With
all simplicity of above there is an ugly question in it there that is VERY complex.
Let say that one of your 110Hz in your specific position hit a G-spot and pick
up some room gain, effectively acting like 140Hz horn. Should you set the
primary resonance at 110Hz or at 140Hz? The different will be very auditable
and what is “better”? This is not so simple, and I do not have a definitive answer.
You can make one horn to feel “better” but then your uperbass image might be
shift unpleasantly. If you have both 110Hz horns siting in acoustic G-spot and become
140Hz horns then stop building hoe and begin to buy lottery... :-)Rerurn to Romy the Cat's Site
