LOL I am glad you took that with the constructive intent it was given.
If you look at the graph of response for the single-reflex enclosure, YES on paper it is higher, flatter, & more "responsive" on the graph... the GRAPH is assuming you have one HELL of a midbass that can pick up at say 55 or 65Hz to fill in before that brick wall drop starting at about 75-80hz...
Like I said, Single & dual reflex (single/dual "bandpass") enclosures were the rage in the late 80s through the late 90's for SPL machines looking to make a dedicated shot at a given range of frequencies. They are NOT musical. They are VERY one-sided. They go low, they are VERY efficient in the range, usually 1, maybe 2 octaves.
If you are aiming for SQ or Even SQ+ type competition or trying to showcase Sound Quality... Sealed is easiest to tune, Ported will get you a lil more depth & impact, but does require, like the bandpass, a VERY strong midbass transition.
From a seamless, Sound quality point of view, your current set up, ported is going to destroy anything the bandpass may have offered and, most importantly be more MUSICAL.
You are an an amazing build journey. Can't wait to see it unfold. Glad that the bandpass wasn't in the cards... you will be too, once its all done... Cheers!
