The Grain Audio Passive Bookshelf System (PBS) from AC Gears is a product designed to fulfill the needs of professional musicians and artists in dressing rooms at performance venues. It was originally handmade as a unique piece, and the design shows the individuality that simply cannot be found in products that are designed to be mass produced in factories by the hundreds and thousands. The key to this originality is the natural look and feel the FSC certified walnut wood brings to each speaker, ensuring that each PBS speaker looks different from the rest. The resonance created by the sound bouncing off the wood is also something that factory-made metal and plastic monstrosities can never match. It’s mellow and clear and pleasant to the ears, but without sounding muffled.
