Simple field assembly reduces labor costs
The JBL 4670D provides powerful, smooth and accurate reproduction of cinema soundtracks from a compact and cost effective system. The system is comprised of two parts: the 4670D-HF high frequency pack and the 4638TH low frequency system.
The 4670D-HF high frequency pack features the JBL 2446H, 100 mm (4 in) diaphragm compression driver, JBL 2380A Bi-Radial
®
horn and JBL 2509 adjustable bracket. Together, these elements provide clear, accurate repro- duction of the mid/high frequency information. All of these components come pre-assembled to reduce field assembly time thus reducing installa- tion costs.
The 4638TH employs the latest in JBL low frequency transducer technology offering exceptional performance ben- efits. The JBL 2035H 380 mm (15 in) transducer employs a copper-sleeved magnetic pole piece providing a sta- bilized magnetic field which provides lower 2nd and 3rd order harmonic distortion and flat power response. The copper-sleeved pole piece
reduces flux modulation and acts as
a shorted turn causing the impedance curve to flatten at higher frequencies. This helps in maintaining a smooth transition between the low and high frequency devices in the crossover region producing, among other things, accurate reproduction of dialog throughout the entire listening area.

Please note:
Crossover not included
If you are going to use this system with an external Crossover for Bi-Amping set up you will require an Electronic Crossover.  If you are planning to use this as a passive system you will require a passive crossover . Neither is in included in this offer. Consult with us for suggestions and a quote if needed. Photos are typical of several in Stock.
