I will be owning a set of DLS 3-way UR36i components soon. I want to try the mid-bass w/ and w/out baffle. I have an extra set of foam 6.5" XTC baffles laying around and I'm hoping to use that as the enclosure. On the on-line manual it states that the general cF required for a 6.5" is around 10-12 litres which works out to about .4 cF. And if I calculated the xtc baffles right (6" * 6" * 3.25") (.5' * .5' * .27') to .07 cF really small lol. Unless I did the calculations wrong.
