Searching for the most "accurate" speaker (below 15K)

Easy - studio monitors like ATC SCM 50, PMC MB2, Grimm LS1
consider active versions - best bang for buck

Grgr4blu i am sure you are the expert on accuracy in all matters of life.

Oh by the way you are hijacking the thread.

how about something like a series one magico s3 - there were a few here that had a price in the 11-14k range. the series one s1 could be had at well below budget there is/was an s1mk2 listed a week or so back in the same price range.

if you want something less "straight to the source", raidhos might be up your alley. the ceo told me he likes pairing them with nagra (along with a few other brands)

dealer disclaimer: i carry raidho, but i do not carry magico

Excuse me, any speaker that has rolled off tremble above 12 khz is  far from accurate, possibly ridiculous, depending on how much. If it is true, I don't understand how they can be taken as something that is worth consideration.
