I built it years ago from plans and parts bought from Germany. No idea how it compares to anything else but I like how it sounds. According to REW and my basic measurement mic it doesn't do much under 40Hz but is can really load the room from 40 to 100Hz.
Oh yeah I’ve got that REL T5 for sale but now I have a point of reference for what a sub can do I would only really recommmend that for a very small room.
