I have had my heart set on a SVS 20-39cs for some time, but it looks like I will not be able to justify the cost. I came across some specs for an 88.5 liter sealed box designed by Adire especially for the Shiva driver. This and an amp will be well within my budget, and I absolutely love being covered in sweat and sawdust all weekend. Anybody have pics of this sub? Do you like it? Have you compared one to any SVS? Thanks for your help.
