That is a hellofa deal. Those subs are amazing! Extremely efficient and the sound quality is very similar to a Fi Q. Just dont feed them much over 600w each. The high roll butyl surround wont allow going past the 14mm xmax very far, but when its already 4db more efficient than most other subs out there you wont need to push it that hard //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif.
