I agree that a 1/2" or bigger radius is easier and looks nicer, but I don't think it works out well on the Neo 2X cabinet if you plan to use a grill. The woofer o.d. is 7-1/4". The width of the cabinet is 8-1/2". If you use a 1/2" radius, that leave only 1/8" on either side of the woofer before the radius starts to bend. If you don't plan to use a grill, then a 1/2" radius would be fine on the Neo 2X cabinet. With the Neo 3 cabinet, a 1/2" or 3/4" radius works very well since the woofers are smaller and there is more distance from the edge of the woofers to the edge of the cabinets. This would allow space for a grill to be installed.
