It does sound pretty good - on the horn thing - the radius and mouth/throat are tiny to have any effect. Idea was indeed to have it look better haha But it would have some effect for sure.

I'm surprised no one has mentioned Dumble. There's a respected amp builder who makes his cabinets "different" than a simple open back. (According to the story, he wondered why no one dared to do anything else, tacked the idea and now it's a standard feature...)

There are also the forte guitar cabs. they had reflectors inside and slots/holes on the sides to direct the back wave.

More seriously, Fuchs Audio Technology has used acoustic damping wool inside their guitar cabs for years, along with such other sacrilegious practices as using small cooling fans to keep chassis temperatures where they belong.

I tend to throw a cheap Walmart pillow inside every small guitar cab I make. Acoustic filling is most effective in the middle of the cab's air volume, where the air velocities are highest, rather than on the cabinet walls, where there are acoustic nodes (and therefore no air movement!)

The pillow causes a small but audible reduction in boxiness, which I prefer.

As usual with music and creative arts, there isn't a single correct way to build a guitar cab. I have heard good guitarists who use a "boxy" sounding cabinet as part of their guitar tone, to good effect. These guitarists are usually going for an overdriven, midrange-dominant sound, and the "boxy" cab helps achieve that.

I'm a little surprised nobody's brought up electro-acoustic guitar cabs yet. Most "acoustic" guitars are plugged in these days, and many of the small acoustic guitar (combo) amps I've heard sound atrocious to varying degrees. Some are so boxy, they sound as though you're somehow playing your guitar inside a bucket.

In my experience, electric guitars are relatively insensitive to bad cabinet acoustics, while (electro-)acoustic guitar's are much more sensitive to them, so poor cab design really does a number on your acoustic-guitar sound. But most acoustic guitar amplifier manufacturers don't put much effort into their cab design.

For years now I've continued to use an Acoustic AG30 I bought as my "starter" acoustic guitar amplifier; I keep using it because it's less boxy-sounding than anything else I've heard even at at twice the price.

Probably not coincidentally, the tuned, slot-loaded, bass reflex cabinet is far from the usual right rectangular prism ("brick") shape (see photo), and only two of the six cabinet walls (the two side walls) are actually parallel to each other. This probably weakens internal standing waves considerably.
