Default Bassreflex design: port diameter is larger than speaker, will it work?

**Nonsense. The lowest useful frequency from a bass guitar is higher than
80Hz. Almost no fundamental is audible. It's all second harmonic.


Because it's an amplified instrument, the amount of fundamental present
depends purely on how much you dial in. That, of course, depends on a lot
of things, but an amplified bass is still quite capable of generating
large amounts of 41Hz.


**I've measured a few and none (that I've measured) deliver appreciable
amounts of fundamental. By appreciable, I mean more than 10dB below the
second harmonic.


Commercial bass guitar amp manufacturers tune their cabs to between 40 and
50Hz. Some even mention this on their websites. If you can show me a
company that tunes to above 80Hz, I'll give you a banana.


**Tuning above 80Hz would not be smart. Tuning APPRECIABLY below 80Hz is
simply wasteful. There is no point in tuning to 50Hz. IF (and I have
certainly not measured every guitar) a guitar exists that delivers
appreciable fundamental, then and only then, would there be a point to tune
at or around 40Hz.
