I agree with Fozzz.

I have had JL's and a Focal Utopia and have found my current IDQ10's to sound the best by far.

Try different box alignments. I found that a box slightly bigger than JL's recommendations yielded better results. Try a 0.8 cu.ft/chamber enclosure.

If you are going focal, i would recommend the Polyglass series, they are very dynamic and have a great response and small box requirements.
