Blue Sky Sub 8 MKIII - Single – No Longer Available

8" woofer and fixed or adjustable crossover
MFR# Sub 8 MKIII

Product Description

The Blue Sky Sub 8 MKIII is a compact and powerful subwoofer, ideal for providing bass reinforcement for studio monitoring systems. The durable MDF cabinet houses an 8" high-excursion woofer with a vented motor structure and a cast aluminum frame to deliver frequencies as low as 20Hz. An internal amplifier provides 100W of power for a strong, distortion-free performance.

The rear panel features XLR input and output connectors, a gain control knob, and filter controls for adjusting the subwoofer's crossover frequency. The Sub 8 MKIII also has a voltage selector switch for international use. A set of durable isolation feet decouple the subwoofer from the floor to minimize vibrations and audio reflections.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
