Its a matter of trial and error. And yes, that is a pretty small port for it, not to mention the ratio is stretching the boundaries already for having resonance issues. And the point of it IS to disrupt air flow, at least in terms of propagation patterns. As far as stopping it, that depends on the frequencies and the power, but mainly the acoustical effects of LF response pass right through it due to the length of the sound waves and the timing of each cycle. This is why it stops the higher frequencies first, due to wavelength characteristics.Also, "airflow" and sound wave propagation are two complete different concept. The connection between the two are in terms of efficiency, and that, yes, will decrease a bit to create the effect you are looking for. It is pure compromise when it comes to purposely manipulating the sound other than using gain and acoustical boundaries of the such.Putting anything in the way is usually not good for the efficiency, but in some cases where filters are needed, this is ideal due to the density of the material.But yes, again, that port is fairly small and may change things more than you hope for-much like a CC where the larger it is, the smaller the changes, the same applies to the port. SO, having such a small port may give you less points of one sound to another to utilize in tweaking the effects properly.Never know till you try it though //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif. I would like to hear how it works out also!</blockquote>
