The “New A series” with the product which is categorized to the middle class of JBL, in each case, 38mm diameter adopting the “tangential ring tweeter” of new development. As for A660 165mm diameter woofer 2 basis and 1 tweeters, as for A60 the 165mm diameter woofer and the tweeter each 1 bases, as for A66 the 133mm diameter woofer 2 basis and consist tweeter 1.
As for the tweeter, the individual the ring diaphragm which has the “tangential rib” with the center cone and the ring tweeter which is inserted with outer horn, outer horn of aluminum die-cast make prevents the unnecessary vibration of high pass, guaranteeing the renewable energy which is room to the crossover territory. We have assumed that high pass quality and the directional characteristics where the center cone held down high pass phase interference are shown.
The damping film was laminated adopting “Dual Layer LaminatedDiaphragm” to the diaphragm. High pass resonance of the diaphragm itself was absorbed, smooth frequency characteristic was actualized with flat. The tangential rib of the diaphragm makes drive stress of voice coil the whole diaphragm disperse equally, assures the control of accurate drive and the high frequency strain component to the high frequency territory.
JBL A60
As for voice coil with the aluminum make, with copper coating lightness compatibility high drive characteristic. Approximately 50% light weight conversion was actualized in comparison with general copper coating voice coil, you say that high pass playback ability was raised. In addition, the vent hole can be less crowded, it assured the cooling effect in the bobbin, adopting “Kapton Vented Voice Coil Bobbin”. The back pressure which catches on diaphragm back is let escape, we have assumed that occurrence of the distortion is held down.
Furthermore, to provide the back chamber on the diaphragm rear, improvement amplitude characteristic. While there is no stress with the multiplier effect of the vent hole of the bobbin, high pass playback was made possible, you say that the being connected of smooth sound of the woofer was actualized.
JBL A66
It puts the copper cap to the center pole piece, absorbing the magnetic modulation distortion. You hold down the decrease of 3 next distortion factors, and the impedance rise with high pass guaranteeing the energy which it covers to super high pass. We have assumed that the transparent impression and articulation furthermore were raised.
Which enclosure as for piercing board finish of cherry natural wood. The terminal of A660 corresponds to bi- wire connection.
