Its a solid subwoofer nice neo motor, solid tinsil leads stitched to the cone beefy voice coil. Pretty stiff spider has some slight give to it but not loose all. The cone has a good costing on it with a thick dustcap made of Carbon fiber and is light weight despite its massive size. The basket is solid and strong with no play to it. Very well made all in all. Only downside I have is I'm unsure about the venting to it as its a open baset and motor there is no where for the air to move on the coil from what I've seen perhaps I missed something so it will warm up faster than some others from my experience. But it has never gotten hot yet nor any stink from the coil. Solid sub great if you want a neo woofer but don't want to spend 2k+ on one but still have a really good pice of equipment.
