Description :
The advanced research and quality of performance make the Model 104 loudspeaker a reference in its own right. The reference series Model 104 is a three-way speaker system employing synthetic, laminated diaphragms for all three units. A 320 x 210 mm bass radiator is acoustically coupled to a 200 mm driver at frequencies below 45 Hz. The combination gives clean bass down to 30 Hz with higher efficiency than would be possible using a single large diaphragm with the same motor assembly.
