I'm trying to LspCAD to design a box and I'm not sure if I'm doing it right. I have a 12.5'x12.5' room with a sliding door to the rear closet that is 2'x4' (Sub could go in closet, but doesn't have to.) I've put in the following in LspCAD The Adire Alignment looks good in it, but I can't build a sub that big for this small of room. WAF. Such a waste as I already have a Tempest. I've put in a ported 97l Shiva and it looks good. Not as loud as the tempest but over 100l smaller and I never play really loud anyway. A 122l sealed tempest looks like it rolls off too early and I'll miss some of the lower bass. This is the max size I could go. This will 90%ht/10% music. Can anyone try plugging in my room dimensions and tell me if my findings are correct. Or give any suggestions. I'd like to stick with Adire as they have had great customer service, and they are somewhat close to me. Thank you.
