For sale: 1 Pair (2 pieces) Philips Ribbon/Isophase magnetostatic leaf tweeters. In that time one of the better tweeters on the market. Impuls, distortion, transients, compression and dynamics all often better then most dome tweeters. Used in many FB Philips speakers or used in the Topmodel MFB with also this tweeter or DIY projects! Its as good as almost matching pair. Its booked as an 8 Ohm tweeter, but its Nominal Impedance is 7 Ohm with a tolerance of +/-7%. Both tweeters having almost same productioncode and are still matching the Thiele Small specs within 7 Ohm +/- 7% ???? Feel free to follow me for more vintage audio and speakers ???? (parts). Sold privately as it is, tested to work 100%. If you have any questions regarding this offer please do not hesitate to contact me also regarding shipping locations and final shipping and packing costs. Happy bid!
