Inside Voice I have see this box in person and that what it looks like. I took my flashlight and third design is correct. Don’t know why it’s called that, all I know is that it goes low and loud.
@Sami Scoda Although the looks from the outside looks the same but the whole build is different from a genuine Bassboss. From the internal specifications, amplification, programming, proprietary limiter and so on…. Lol
I think the short horn adds the bunch and transient response whereas the actual porting and large size of the cabinet allows the LF extension. I have two of them. Pretty impressive. Most horn loaded/folded cabinets can’t go as deep as similar sized ported cabinets in my experience.
