I built the 142L vented adire box a few years back and now i want to downsize (it's way too awesome for my apartment building, people keep asking if there was an earthquake everytime i turn it up!!) But Adire have taken down their plans, does anyone still have them? Or can anyone give me rough dimensions for a smaller box? I'm thinking sealed because the smallest vented plan was still 90L if i remember correctly. And i'd like to get it down to 18" cube with the amp inside the box. I think sealed will mean less headaches for me wrt to getting the exact correct volume. Thanks for any ideas!
