SLJ, youre right, the nearside box is tiny. The offside one is 1.24 litres which is fine for most 10 or 12" subs, but 0.75 litres is way too small for anything above an 8" sub unless its optimised for a small sealed enclosure. I think the wadding they use on the inside of the boxes helps to give the impression of a larger baffle though (ie. fools the sub into performing like its in a bigger box!), so perhaps its ok. Ive ordered a pair of stealth sub boxz which should be coming tomorrow, Im putting Vibe 10"s in them. Should be interesting to see how the sound differs from the different sized enclosures.
