in try to gain space using thin walls
indeed, and it saves money doing all you can out of mdf also, but im sure you know that now, lol, but it also depends on what woofers you are using if they are low excurions woofers you really shouldnt have any problems, but a good woofer will flex the hell outta that box, a real big woofer could even blow it apart //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.giflol the only thing your gaining is flex. thin walls dont help your enclosure EVER
i have a question as to how mounting the rings that way is going to work
