Description of outdoor acoustics PMC Twenty 23
Younger floor model in the anniversary series acoustics from the renowned British manufacturer, Twenty 23 looks just gorgeous. Tilted back speaker Cabinet has a natural wood (a choice of Walnut, Amarone, Oak and Diamond Black), and looks like it is a monolith.
PMC Twenty 23 speakers are equipped with custom tweeters Seas company, with a 27-mm soft dome Sonolex patented material, and specialty 140-mm WOOFER with a cone made of pulp impregnated. So managed to get a light and stiff cone, almost do not have their own resonances. The speaker is mounted in a cast metal basket.
One of the main features of acoustics PMC is use for load woofers transmission lines (acoustic labyrinths). He is a channel formed by internal partitions of chipboard thickness of 18 mm in the case of the AU, and having a substantial effective length (in model 23 Twenty it is 2.4 meters). Acoustic labyrinth provides a higher quality and the length of the low frequencies than a classical inverters, but also significantly more difficult to manufacture and configure, so there are a few companies equip their AC. The outlet of the maze is located at the bottom of the front panel, so Twenty 23 can be placed close to the wall. Mentioned the tilt of body column allows not only to give the AU the original appearance, but also to synchronize the radiation of the tweeters and woofers, so that the sound waves of the relevant frequencies at the same time came to the listener.
PMC Twenty 23 speakers are equipped with separation filters, audiophile grade components, which are assembled and adjusted manually to fine tune their parameters for specific instances of dynamic heads. System speakers Twenty 23 operate in the frequency range 29 Hz – 25 kHz, have an impedance of 8 Ohms and a sensitivity of 87 dB. The column is equipped with two pairs of input screw terminals, providing the ability to connect to the amplifier according to the scheme Bi-Wiring/Bi-Amping.
