Noob: Punisher MKII frequency response plot? and other cab recomendations..

Im a noob and looking to build some growling bass horns for myself, hoping to bring some good vibes to the world as this covid thing lifts.

I used to have a double stack of martin 115B bass bins and matching tops.. Looking for that sound again in a modern smaller more efficient package.

Someone on speaker plans recomended the punisher mkII..But I cant seem to find a frequency response plot to back up the 50-200hz claims or to see how flat it is. Does anyone have this Frequncy respose plot data??


Does any one have more info on this design? Or can they direct me to the designer ? Is this design dependent on a high end expensive speaker to get the enclosure to preform? Seems like slim pickings on info....

Im also open to recommendations on other cabs that will bring that horn dub growl in a modern package

Thanks folks!
