I started my Shiva box subs today. I am using the vented EBS alignment from Adire's web site. I started at about four o'clock and spent the rest of the day cutting out all of the 4" brace holes, 36 in all. I am going to cut the driver and vent holes tomorrow. The reason I chose dual boxes, instead of one big sonotube, is because I want to use them as stands for my nOrh 6.5s. Also I want to cover them with a nice rich looking wood veneer. Currently I am planning on cutting some simple legs from hardwood. Does anyone have any good ideas about where to buy some attractive wood legs for a box sub?
