For sale the Bastanis Mandala Open Baffle loudspeaker. These have the upgraded Chrystal wideband drivers and Gemini tweeters. These speakers were part of several show exhibits that garnered much praise and won a Gold Show Award at the 2015 New York Audio Show in Westchester. Everything that is needed to put them up in your room and play mucis is included. They come with Dayton woofer amps. The wiring is upgraded to silver hookup wire as well as an Urushi-layered capacitor for the tweeter. They are 100db+ efficient so any low-powered amplifier will work effectively. I have been with Bastanis for a number of years and can attest to their dynamics, resolution and portrayal of a believably large soundstage that a box speaker simply can not achieve. You can see on my website beautyofsound.com a number of videos where these speakers are showcased.
