Vandersteen Audio has done its best to photograph these wood finishes on each product page, but please know that while the woods we receive from our vendors are unfailingly high in quality, no two pieces of wood are ever exactly alike. This is dictated by nature. We promise that your speakers will look gorgeous, but not that they will precisely match the photos you see on our website or on our dealers’ in-store demo speakers.

The Vandersteen System NINE Bedrock Granite Base is specifically designed to retrofit onto all Model Seven floor standing speakers.  This special base is fabricated from different types of materials used together to dampen vibrations and to add mass to the Seven Cabinet.  The base yields a new level of sonic presence, sound field expansion and bass clarity never before heard.  Vandersteen recommends this as your first step towards the full System NINE.  The Bedrock Base has proven so important, it is included and vital to the performance of the Model Seven XTRM.

    System NINE Bedrock
    As we discussed, I ordered and installed the bedrock upgrade on my MODEL SEVEN MkIIs.  I picked the "rocks" up from my local dealer about a week after I ordered them, so that was quick.  The installation was straightforward and didn't take long.  I could go on and on about all the improvements, but you know what they are because you designed them.  Frankly, I was shocked at the magnitude of the changes.  Wow, I am happy.  In fact, if I didn't know that the only thing that changed was the addition of the "rocks," I would not have believed it.
    I will also say the bedrock design and finish make an already good-looking speaker even better looking.
