For over a decade, JBL SR and SRX series speakers have represented the best performance, highest quality and most advanced driver technology available to portable PA users. The SRX700 Series continues that tradition and moves the bar even higher. The advanced technology of SRX700 Series speakers delivers the power and performance that you would expect from the highest quality, professional rig. At the same time, JBL innovation and design have reduced system weight so load in and out are a breeze. All this performance is housed in rugged birch enclosures for years of superb performance.
JBL SRX722 – Dual 12" Two-Way Loudspeaker :
Taking a page from high performance hot-rod design, JBL filled the smallest possible cabinet with the highest possible power capacity. Especially suited for subwoofer-equipped systems, the SRX722 delivers very high acoustic output from a compact, easily transported system. A pair of 2262H Differential Drive woofers handles 1600 watts (continuous) of power. Top these off with the world-class, 2452H 4" compression driver, and you have big PA performance that fits easily into a sport utility vehicle.
JBL SRX722 Features :
- Light-weight, compact and very high-power.
- Dual 305 mm (12 in) Differential Drive® low-frequency drivers for very high acoustic output.
- 102 mm (4 in) voice-coil neodymium compression driver for high-power capacity and very light-weight.
- 75˚ x 50˚ coverage.
- Bi-amplified or full-range passive operation.
- Flying version available (SRX722F) with five suspension points may be used with optional M10 eyebolts or detachable track fittings.
High Power :
Amplifier manufacturers are building amps that can produce more power at less cost than ever before. The SRX700 series lets you unleash that power with a new generation of high-power low-frequency drivers. That would be enough for most manufacturers, but JBL accomplished this while also greatly reducing the weight of the drivers.
Incredibly Lightweight :
SRX700 uses JBL’s patented Differential Drive® woofers with neodymium magnets. Neodymium's magnetic properties allow a few ounces to replace pounds of conventional magnet material. While other speaker manufacturers may use neodymium, JBL engineers created a design that reduces the massive (and heavy) steel top plates, back plates, and pole pieces that complete the ”magnetic circuit“. The JBL Differential Drive design uses two voice-coils for greater power handling and actually puts the small neodymium magnets inside the voice coil. This design greatly reduces weight while increasing power capacity, decreasing distortion, and reducing power compression.
Suspension :
Flying versions of the SRX700 two and three-way models are also available as SRX700F models. These offer you the option of selecting economical, forged eyebolts for fixed installation or the convenience of detachable track fittings for portable applications. Just choose the hardware kit that's right for your application.
Bi-Amp or Full-Range Operation :
All SRX700 two and three-way models may be operated full-range or bi-amplified. The selection is made by means of a high-current, recessed switch mounted on the input plate. The switch is accessible while also being protected from accidental mis-setting. The same switch arrangement is used on the subwoofer to select ±1 or ±2 operation.
Construction :
SRX700 is constructed of top quality birch plywood and coated in JBL’s rugged DuraFlex™ finish. Extensive use of internal braces and bulkheads makes the enclosures extremely rigid. This reduces acoustic losses caused by panel resonance. The attractive CNC-machined, 16-gauge steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the system to create acoustical interference. The grilles are internally lined with acoustically transparent foam to provide additional driver protection and give a totally professional appearance.
The JBL 100 Hour Torture Test :
Put on a set of industrial hearing protectors, step through three sound-proof doors and you’re in the JBL power test room. This is where JBL speaker designs are pushed to the limit. In 100 hours, we subject a new design to more abuse than it’s likely to see in a lifetime of real-world use. The systems are pummeled by high-power amplifiers pushing shaped random noise with a 6 dB crest factor into the speakers. This test pushes the thermal and mechanical limits of woofers, compression drivers and cross-over components. If there’s a weak link in the system design, this test will find it before the design is finalized. No one in the industry uses a more demanding testing standard.
