Description

Sundown Audio - SALT 500.4The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class D amplifier technology. They stand on the shoulders of the previous three generations of Sundown high end Korean amplifiers spanning 15 years (the SAZ v. 1, SAZ, v. 2, and SCV series) to reach even greater heights of performance. Our customers, for many years, have asked us to produce amplifiers that produce optimum power at realistic operating voltages in the 12s rather than 14+

The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. They stand on the shoulders of the previous three generations of Sundown high-end Korean amplifiers spanning 15-years (the SAZ v.1, SAZ, v.2, and SCV series) to reach even greater heights of performance. Our customers, for many years, have asked us to produce amplifiers that produce optimum power at realistic operating voltages in the 12s rather than 14+ volts. The SALT – Sundown Audio Low-Voltage Technology – series is our answer!

Whether you are a world-class SPL competitor, a dedicated enthusiast, or even a fan of Sound Quality the SALT series will be right at home in your system. Each and every model has been created with painstaking attention to detail to ensure that they bring a smile to your face each time the music starts playing and, further, to last for many years to come.

Cosmetically they are a huge departure from our original styling as an outward indicator of the enhanced levels of performance. The heat-sink is the heaviest we have ever produced, with the most surface area, and is finished with a striking titanium color. These amplifier looks as good as they sound and as soon as you hold one in your hands the build-quality is obvious. The icing on the cake lies in the revised remote control which features temperature, voltage, and clipping indicators to easily monitor the vitals of your valuable audio system.

    These work for the Worx trimmer WG928
    Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
    Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.

    Works like original equipment
    Size: 16 Line Spools+4 Caps
    Seems to handle the same work load as the manufacturer part. Good quality fit and design. No problems installing the string on the trimmer head. Definitely worth the purchase.
