By 'smaller' do you mean anything smaller than the 21"? :gulp:The smaller drivers NEED to be ported, to give the extra headroom. The 21" has an abundance of output, without the need of porting.
Top stuff mate. Can't wait to follow your build thread.Yes, it's a done deal. I gave Kevin a call to hammer out a few details...get this, he's actually talking me down from a 15 cf cabinet to a 10-12 cu cabinet! Anywho, he's got my Credit Card and I'll have a 21" on the way soon. Expect a build log here in the X forums.
