I enthusiastically agree with Chadnliz--just about anything I've ever run outdoors sounds surprisingly good. Used to have a pair of Niles OM-5s that were excellent, and lately, I've been carrying a pair of B&W DM303s into the yard on outdoor days while I'm waiting for delivery of a pair of "off brand" outdoor speakers from an online shop. I'd spend conservatively. . .just getting rid of all those walls makes the extraordinary difference. But beyond that, you're competing with ambient noise, and you're probably not glued to the "sweet spot" so it seems there's a rapid accelleration of the diminishing returns principle.
