Contents of the lot: A set of Panasonic SB-PMX/1 In as good as new condition. Year of production: 2006. Impedance: 4 ohms Nominal power: 60 watts max. 120 watts Frequency range: 41 - 100,000 Hz Dimensions: 24 x 26 x 16 cm (Height x Width x Depth) weight: 4 kg/speaker The SB/PMX/1 is a very successful design and an absolute hit in this range. The speaker sounds mature and is very pleasant to the ear. Behind the cable connectors, a crossover has been placed which divides the incoming signals on the three chassis of the speaker. Panasonic has made something special. Instead of going for the usual 2-way system for this size, the Japanese developers chose to divide the frequency range in three ranges. In the low/middle area, a 140 mm woofer is used with a light and extra stiff cone membrane. Along with the solid housing and the extra long bass reflex tube, these characteristics provide a good impulse response, deep reaching bass reproduction and high power handling. In the high frequency range, Panasonic uses a 25 millimetre softdome tweeter with a neodymium magnet system. The highlight is the Panasonic super tweeter. With a membrane of only 12 millimetres, this produces the highest frequencies (15,000 to 100,000 Hz!). All my audio equipment is professionally checked and tested. At this company in Zuidlaren the equipment always get cleaned and repaired if necessary. The speakers will be sent worldwide in a double box, boxed twice. Collection from Haren, near Groningen, is possible as well.
