Need speakers that can rock with just one watt? You found da place.

Re: midbass suckout?

The gap is on part to the big vent, and in part the floor.
Notice the reflex has it too. The gap looks deeper because the output is higher- 5dB higher past 200Hz. That is the idea of half of a horn.
You get the hit, and you get the bass. The half horn is matched to a JBL 2226, but the D130 will work.
I found it curious that the very loud 300-2kHz area of a D130 ( light cone-big motor) was swamped by the low end.
I chose 5cft for the ( BR) d130, as that was the best comprimise beteen some bass and no bass.
