I can't speak to whether distant microphoning produced too much level in the ultra-low frequencies?

I have never owned a ported design so I can’t speak to the distortion levels but I understand that sealed systems do provide more abundant bass than a comparably rated ported system. That’s because a ported system’s bass falls off like a rock while a sealed system bass rolls off much more slowly. So, while a ported system rated to down –3db at, say, 40Hz truly has almost no meaningful bass below that point a sealed system bass response rated at 40 Hz –3db will roll off gently and produce a meaningful response for another 1/3 of an octave or so.

Of course, that same ported speaker can be designed significantly smaller and more efficient because of the port, that some say can make audible noises in some speakers. This is probably the main reason why there has been a proliferation of ported designs and a commensurate decline in sealed designs.

Regarding the foam surround, the low humidity in the Reno area may ensure a longer life for the surround. Don’t necessarily expect a gradual deterioration in the way the surround looks. One day things can look fine and the next day you see cracks and holes. There may be a deterioration in sound quality but it is unlikely that you will notice it because of the gradual nature of it. Once the surround is replaced you will quickly notice the improved bass definition
