Coincident Pure Reference Speakers – In Excellent Condition These are THE BEST speakers I have ever owned! They literary disappear and provide an emotional window to the music. Only a small number of much more expensive speakers are able to perform like the PRs from Coincident. The speakers are from 2010. They include the optional bi-wiring and the factory upgrade to Dueland capacitors. I still have the original boxes but would prefer local pickup, since the speakers are very heavy (196 lbs each!). Israel Blume’s speakers are not famous for their high-end fit and finish. They convince through pure performance. The laminated cabinets have small manufacturing imperfections, which could be fixed if needed (see photos). I am the original owner. The speakers were always kept in a smoke-free and air-conditioned environment. They were never abused! Included are custom made platforms using axial ball bearings to effectively decouple the speakers from the floor. I’m selling these beloved speakers because I downsize, and will not have the space for a large stereo system anymore. Specifications: Frequency Response: 20 Hz – 35 kHz Sensitivity: 94 db @ 1m – 1 Watt Impedance: 8 Ohms totally flat Minimum Power Requirements: 3 Watts (can be driven by SET Amps) Dimensions: 55.5” H X 9” W X 24” D Weight: 196 lbs each Driver Compliment Per Speaker: 1 – 1.2” Accuton Ceramic Tweeter 1 – 6.5” Accuton Ceramic Midrange 2 – 12” Nomex Fiber Woofers Bass: Very tight bass tuning - which makes it easier for low damping factor- high output impedance amplifiers like SETs to control the woofers. Simple first order crossovers which do not rob amplifier power or reduce speaker sensitivity. The most detailed review of these phenomenal reference speakers was published by Arthur Salvatore on his webpage high-endaudio.com. theaudiobeat also published a nice review. Since ebay does not allow including links to webpages, please google those two sources of information. Please email me with any questions.
