SONODYNE SJX 1208

Product overview

The SONODYNE SJX 1208 is a two way compact line array loudspeaker with dual 8 inch woofers, rated 600 W (AES) with a maximum SPL of 124 dB per box.

It has a clear, detailed response and can be flown, or ground stacked, for both installation and touring applications. The SJX Series is SONODYNE's range of passive line arrays with dual 8, 10 and 12 inch LF drivers: high power transducers chosen for a balanced tonality and exceptional dynamics, and a custom waveguide that gives wide horizontal dispersion while allowing large vertical coverage when several elements are aligned.

Key features

• 2 way compact line array with dual 8 inch LF
• Max SPL 124 dB continuous with 800 W program power handling
• Computer designed waveguide for path length equalisation of high frequencies
• Low distortion drivers for clear audio at long throw distances
• Durable 18 mm plywood enclosure
• Wide, uniform 100° horizontal coverage in all system configurations
• Variable vertical splay angle in a compact form factor
• Efficient crossover network for a linear response at high output levels
• Flying and mounting solutions

Trapezoidal plywood enclosure

The trapezoidal enclosure is 18 mm plywood finished in durable black paint, with a powder coated 18 gauge perforated steel grille. All SJX models are built this way to be roadworthy. The SJX 1208 measures 630 x 280 x 370 mm (W x H x D) and weighs 26 kg.

Transducers and waveguide

The LF section is 2 x 8 inch with 2 inch VC; the HF section is 1 x 1 inch with 1.75 inch VC, on a computer designed waveguide that equalises the path length of the high frequencies. The SJX literature rates the drivers at LF 2 x 300 W AES; HF 50 W AES. The crossover point is 2 kHz and the efficient crossover network keeps the response linear at high output levels.

Performance

Frequency range is 55 Hz - 20 kHz (-10 dB), sensitivity 98 dB (1 W, 1 m) and maximum SPL 124 dB continuous and 130 dB peak. Power handling is 600 W continuous, 800 W program and 1600 W peak at 8 Ω nominal impedance. HF directivity is 100° x 15°, and the 100° horizontal coverage is maintained under all system configurations.

Flying and connections

Each cabinet has a standard bracket for flying with a vertical tilting arrangement; the side plates are marked 0° to 10° in 2° steps. Up to 8 cabinets can be flown using the truss head (SJX TH8, sold separately). The rear plate carries a twist-lock input and a twist-lock link.

SONODYNE SJX 1208: frequently asked questions

Is the SJX 1208 active or passive?

Passive. It is driven from an external amplifier through its twist-lock input; the link connector passes the signal to the next cabinet. Nominal impedance is 8 Ω.

How many cabinets can be flown?

Up to 8 cabinets can be flown using the truss head for flying; for the SJX 1208 this is the SJX TH8, sold separately.

Can it be used outdoors and for touring?

SONODYNE states that SJX cabinets can be flown or ground stacked for both installation and touring applications, and are finished with durable paint to be roadworthy.

Where can I buy the SONODYNE SJX 1208 in India?

The SONODYNE SJX 1208 is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.
