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.

horns. The enclosure is constructed of dense stock and is extensively braced on all panels reducing cabinet resonances. Net internal volume is 2251(8 cu ft) and
the enclosure is tuned to 40 Hz with large port tubes, ensuring minimum turbulence at full power input at low frequencies

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.
