- I wonder if the designer of the speaker with ports in
- front and back thought that he might avoid weakening
- the front panel by cutting too large of a port into it.
-
- I think it is accepted that small ports are bad because
- of air turbulence noises not related to the desired
- sound. If this is true, then it would probably be a
- bad idea to split one fat port into two skinny ones.
-
- I wonder if it is possible that there is more to the
- speaker than you have described. Is it possible that
- one port goes to one chamber and another port to a second
- chamber? Perhaps one chamber is midrange and one bass?
- You said that one port is low and one is higher. This
- might support the one-for-mid & one-for-bass theory.
-
- Or perhaps the ports are both for the bass, but one is on
- one side of an enclosed cone, and the other on the other
- side of the cone? This would be similar to the bandpass
- structure used by many these days.
