The second benefit is smoother, more uniform upper bass/lower midrange frequency response in a real listening room. The dimensional relationship of the woofer to the nearby room boundaries (the walls and floor) in any speaker results in a reinforcement or cancellation of upper bass/lower midrange frequencies corresponding to the woofer-to-boundary dis- tances. By placing the cabinet’s two woofers at optimally chosen different locations, these dimensions are "averaged" over a

Connecting the Speakers to Your Amplifier or Receiver Basic Hookup 1. Connect the speaker terminals to the amplifier speaker outputs. 2. Make sure the speaker terminal jumper straps are in place on the back of the speaker. (VR2 and VR3 only) IMPORTANT: When making all connections, be sure to connect + to + (red) and – to – (black).

Bi-amplification (VR2 and VR3 only) Bi-amplification requires using separate amplifiers dedicated to high and low frequencies. Using more than one amplifier can enhance the dynamic performance of your system. “Splitting the load” between two amplifiers lets each amplifier work less hard, increasing the available current to the drive units. When making all connections, be sure to connect + to + (red) and – to – (black). 1. Unscrew the terminal collars of both sets of terminals and remov

How to Place Your Speakers The VR speakers were designed to deliver exceptional bass extension and tonal balance, regardless of where they are placed. However, for optimal results, it is advisable to position the rear of the speaker to be at least 3 inches (76mm) away from the wall or curtains that are behind it. The speakers should also be at least 2 feet (0.6m) from the corners of the room. Putting the speakers too close to a corner can produce an unnatural bass reinforcement that de

Using the Carpet Spikes For placing speakers on thick carpet, we recommend using the four threaded carpet spikes and lock nuts (VR2 and VR3 only) which serve three purposes — leveling (an aesthetic issue), stability (a practical issue) and rigidity (an acoustic issue). The spikes concentrate the speaker’s weight on four points, creating focused pressure that 1 anchors the speaker cabinet to the floor and enhances rigidity. For most carpeting, leaving about ⁄2-inch (12mm) of the carpet
