10. Impedance.
Note 1: Standard impedance's are 4, 8 and 16 ohm. The norms allow that minimum impedance over resonance can be 20% lower than the nominal impedance. Often it is acceptable that a speaker for an 8 ohm system goes below 6.4 ohm to get higher sensitivity. We then write 8/6 ohm to indicate that minimum impedance is 6 ohm, that means below what is allowed according to the norm.
Note 2: Our NXT panels do not fit into above system. A typical code can be:
890202 KAW 594x594 T5 B2 26 25 70V
This means a panel, material: K, colour: White, dimensions: 594x594mm, Thickness 5mm, and B2 is a self extinguish fire classification. The exciter has 26mm voice coil and 25mm Neodymium magnet.. Finally 70V indicates a line transformer adapting to a 70V line.
