This is not how guitar speakers are designed. Reflex speakers are

for a fully sealed box if it is fairly big, or for a smaller cabinet,
have about half of the back panel open.

High fidelity and flat response are NOT what you need for this job.


This is true. Also, 150 litres is ridiculously large for a 1x 12 guitar
speaker. I have a 12" JBL in a 40-litre cabinet for my bass!

The problem with using WinIsd and similar programs is that you must know
the target respons of your planned system, i.e. the frequency response
you are aiming to achieve. Otherwise, it will often suggest an
over-large box that is useless.

WinISD will allow you to tweak the box and port size, and show the
frequency response graph.
So there's no problem.
