Πωλειται ζευγος vintage ηχειων YAMAHA NS-15 ( BIG EAR ).εδω παραθετω τα χαρακτηριστικα τους..Yamaha's NS-15 speakers are a piece of Hi-Fi history. Introduced in 1967, they were the first of the "Natural Sound" series of HiFi speakers for the home; and represent Yamaha's official entry into the US home audio market. These unique speakers utilize a large enclosure with a fairly shallow depth; housing a large styrofoam diaphragm that was designed to mimic the shape & characteristics of the human ear.

The NS15 is a dipole speaker with an asymmetrical 18 x 23 inch woofer/midrange driver with some very special cone material and ALNICO magnet system. Frequencies from 5 kHz up are handled by a bullet-type horn tweeter JA-05036B, the level of which can be adjusted with a three-step attenuator. The cross-over is of a second order, and some EQ is applied to 1-5 kHz. NS15's claimed frequency response is 35-20000 Hz, and the sensitivity 100 dB. ειναι σε αριστη κατασταση πληρως λειτουργικα και ακρως συλλεκτικα και σπανια πλεον.ειναι μια απο τις κορυφαιες υλοποιησεις της εταιριας με ALNICO μοναδες και με το χαρακτηριστικο woofer σε σχημα ανθρωπινου αυτιου.απευθυνονται σε γνωστες του ειδους Eιχαν αγορασθει απο τον μεγαλο ιαπωνα βελτιωτη KENRICK SOUND. χρωμα μαυρη λακα.....τιμη πωλησης 700 ευρω..ΟΧΙ ΑΝΤΑΛΑΓΕΣ-ΟΧΙ ΠΑΖΑΡΙΑ-ΟΧΙ ΑΠΟΚΡΥΨΗ
