Contents of the auction: A set of Panasonic SB-PMX/1. In as good as new condition. Year of production: 2006 Impedance: 4 Ohm. Nominal power: 60 Watts. max. 120 Watts. Frequency range: 41 - 100.000 Hz. Size: 24 x 26 x 16 cm (Height x depth x width) 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 over 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 soft dome 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 of my audio equipment has been professionally checked and tested. At a company in Zuidlaren, where the equipment always gets cleaned and repaired if necessary. The speakers will be shipped worldwide, packed twice, boxed twice. Pick up in Haren near Groningen (NL) is also possible.
