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

Easy no-nrainer - QUADS 
THE most accurate, natural, transparent I have ever experienced in my 60 years in audio.

For room your dimensions we have special model called Acoustic Preference GRACIOSO 1.0 LE (99 pairs only), if you prefer neutral-natural sound. Right now in special 10.anniversary action -40% off, look to eBay or our web site. Sorry, we dont have dealer in many countries, but we offer 45 days of money back warranty. The cost of purchasing with customs and VAT should not be higher than $ 10000; delivery is paid by our company.
Maybe interesting information for you and other audiophiles. Also our bigger model GRACIOSO 2.0 LE will be very good for your room but cost approx.2500$ more also in action now.
A little advertise for our oudspeakers which are not very well known in audiophiles world.

Quad ESL - fast, natural, accurate

and you can also use them to electrocute flying insects!

If you want accurate speakers - someone mentioned the Emminent Technologies - but without the subwoofer, the new Carver ALS would be around 15K.  Though tall, they are very thin and sound good in both small and larger rooms.  TAS menyioned how very similar in the midrange they sound (but better!) compared to the ETs.

The Carvers at $15k, the Eminent Technology at $2499---one sixth the price. The $12,501 difference will buy a swarm of nice subs! Or a whole lotta music.
