I have recently made my second ever pair of speakers, this time a pair of ported full range numbers based on fostex FE126NV. I have a short video of the construction YouTube
I did my sums + stuck my finger in the air only when needed - but I really need to test them properly. I can see one is able to get test programs that will do a sweep through the audible sound spectrum and plot a nice frequency plot. If I do that with a bog standard cheapie mic and my bog standard computer - is that ok? If not ideal, is it better than nothing?
I'm also interested in critique of the design and construction method. Obvious problems I don't need reminding of is slightly sloppy finishing and, more technically I didn't round over the edges to reduce diffraction (part of the look n feel I'm afraid). Anything else is fair game. I think they sound good enough, but I'm no virtuoso listener.

You really should have a calibrated microphone to get an idea of an SPL response....really too many variables without such a mic & some accompanying calibration software.
This driver responds well within the so-called midrange of frequencies of 500 to appx. 5000 hertz...a thirty-one band EQ can flatten it out completely.
I'm finishing up a similar build with some NOS Ratshack FR five-inchers (40-1284E)..in a 0.5 cubic foot aperiodic enclosure. I certainly didn't cough up $71 Euros for your new drivers...mine were the price of a plain sandwich.
