Bluetooth Headsets And The People Who Wear Them Continuously

This post has been swirling around in my head for many months. This morning my wife and I decided to have breakfast at a nearby French cafe. In the cafe there were all manner of people. Large people*, small people, rich people, not-so-rich-people**, singles and couples. It was a typical River Oaks Houston crowd.

This approach allows the designer to tailor each amplifier design to suit the specific driver in question. Amplifier/driver interaction is one of the more complicated things in audio reproduction and optimization here can bring big performance improvements. With the amps right in the cabinets there’s effectively no speaker leads to further complicate the amp/driver relationship.
