Post Subject: 40 - 400 or 90 - 400 Hz?Posted by serenechaos on: 11/13/2008

There's a big difference in 40 - 400 and 90 - 400 Hz.

40 - 400 might also be stretching the bandwidth which will be horn loaded?
(FLHs by nature are narrow band, 40 - 400 is over three octaves...)
And, besides the coloration Romy mentioned, a very long horn will act as an acoustic low-pass filter.

Integration. I mean all drivers having the "same type voice."
I don't know what you plan below 40 or above 400, but they need to have the same general "Sound."
Or you can end up with something that sounds like so many good drivers playing, instead of one integrated "Sound."

Just a few of the problems I've been dealing with in building a 65 Hz mid bass horn.
Which is MUCH smaller than 40 Hz.
But is easy to integrate with a tapped horn from 25 Hz up to where it comes on.
Something that would hit 40Hz does sound like an interesting challange...
