Audiolife, you and I got into this about the W7 a while back and both had about the same outlook on them. Way overrated, way overpriced, and a bit lacking in certain area's. All arround, I believe that JL put too much promotion into this speaker and not quite enough R&D to live up to its hype. I have heard the W7 line many times, and it is by no means totally dissapointing, however, I believe that the company's flagship line, the W6, still has the upperhand.
Getting right down to it, as SQ is merely in the eye of the beholder; for lack of better terms, and SPL can be metered, this would allready be an unfair comparrison between the Adire and the JL.
Pound for pound, I have no doubts that the Adire is Equally capable, if not superior, to the JL. The Adire simply offers its performance at a far better price.
IMO- based on listening and the numbers- I would prefer the Adire either way.
take it easy,
