I'm also surprised by the Polk hatefest on this thread--on previous threads their avid fans have leaped to their defense. Personally, I think Polk's finest work was in the 80s--the SDA, RTA and even the low-cost Monitor series were really good in their own way. I've owned the more modern LSi-7/Lsi-9, which are well-balanced, high-value monitors, but would tend to agree with some of the above criticisms of the larger Lsi-15.
