Yeah i went with the same as Sorreltiger with Qed airlocks, definetly worth getting the xt for fronts and centre.Not sure about Chord Carnival, might give you a little more bass, but look at the thickness can be tricky to run to the rears, depending on your layout.For me door frame had to be considered, and mirco was perfect for that easy to fit as its flexible and still delivers great quality at a reasonible price.Hope you are enjoying your Quads-Lites as much as i am, by the way if you require speaker stands Apollo A1s 7 or 9 at less than £50. Got my from A1 Sounds along with speaker cable cheapest at the time for the Qed airlocls at £3.95 each.
