Re: Respons graphs for FW12.1


I will check, I know it looks lower than it should, but as you can see my room has a dip at 60hz and 75hz and that might be affecting the neirfield, Next time I do measuring I may try without the lowpass, and redo the ones I still have set up.

The outputs have been scaled and averaged as best as can be done, how do you mean off? Remember neirfield measuerments are only close to anechoic, with outside being even closer. So they cannot be expected to look exactly "right"

The ports are done with extra layers of mdf laminated inside the box around the port and then a large roundover bit in a router. Or for our larger ports 4"(when extra flareing is needed) and anything 5" and over we laminate MDF slugs and machine them in a lathe for a 2-3" radius. Then epoxy them into the enclosure.

Here is a picture of a 6" port flare, unfinished. Outer flare and inner flare
