APS IO Active Monitors - Pair – No Longer Available

High quality active near-field studio monitor

Product Description

After market success of AEON, which is designed for listening in near-medium field it was a challenge for us and “natural” step forward into pro-audio world to create an active nearfield studio monitor.  This is how the APS IO was created.

High-quality components used for construction of IO and well thought-out acoustic design have resulted in perfect linearity of processing, at the same time preserving natural sound timbre.  Detailed music transfer and sensational stereophony make IO comparable only to the best in the world designs for listening in the near field.

Sturdy design and small monitor size make it an excellent proposal for discerning users having smaller listening rooms and also those with extended sound processing systems who are looking for reference nearfield monitors.

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.
