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.

    A Green Hard Plastic Sea Creature? Chew Toy
    Color: Green, Pattern Name: Hammerhead Shark
    This is a sturdy chew for my 40 lb retriever who is 9 months old. BUT after she has been chewing on it there are sharp edges which hurt my fingers when she wants me to throw it. It is strong and she enjoys it, so she can continue as long as she wants but, If it cuts her tongue or mouth it’s gone.

    Strongest squeak toy for aggressive chewer
    Color: Green, Pattern Name: Hammerhead Shark
    I have been through so many toys for my aggressive super chewer pit bull puppy. He has shredded the bark box super chewer toys and most super chewer toys. Wet have had this toy for over a month and he still lives it! The squeaker odds in the middle of the toy and impossible to tear out and it still squeaks! This has been a very impressive toy.

    Durable and dog loves it
    I was searching for a squeaky toy but also a chew toy that wouldn’t break my dog’s teeth. We’ve already had to have one tooth pulled because our Jurassic Corgi girl cracked it on either a bone or a yak chew. She loves to play with this bone and chew on it and it has held up well. It still looks like new after several months and she plays with it daily.
