The Roland SST Series professional sound system released in the early 1980s.
The high-performance SST produces clear sounds over an extremely wide frequency range.
The powerful SST-120, acclaimed throughout the world for its pertormance. Is now joined by a complete new line or high performance speakers – the SST-40, SST-60, and SST-80 – all very attractively priced.
The top of the line is still the SST-120 – a 3-way, high-performance speaker system with a giant 38cm (R&P) wooter, a mid-range horn, and a matched tweeters. Specialy designed tor professional use, the SST-120 is characterized by an extremely clean sound, powerful volume, and well-balanced frequency response over a wide frequency range. Switches on the rear panel permit quIck and simple crossover network switching to achieve the optimum response for any conventional audio sources, including PA system, keyboard and guitar. And for easy portability, the SST-120 is mounted smooth-rolling, heavy-duty casters.
The newest additions to the Roland speaker line are the SST-40, SST-60 and SST-80. All are 2-way, high-pertormance speaker systems either a 25cm (the SST-40) or 30cm woofer (the SST-60 and SST-80) and a piezo-ceramic-coated horn tweeter. All 3 speaker systems vividly radiate a pure sound over both mid- and upper high-frequency ranges while generating an impressively strong bass response over the low-frequencv range. The result is a sound so true to its original source that It cannot be matched by any conventional 2-way speaker system.
Additional speakers can be connected using standard headphone and terminals. It all adds up to an audio performance of unsurpassed excellence at a very reasonable price. The new SST-40, SST-60, and SST-80 speaker systems feature a compact, lightweight design easy to install in a minimum of space. They can also be mounted on optionally available speaker stands. All of the SST series speakers are finished in sleek, highly durable black leatherette for a beautitul finish that matches any interior decor.
