Sound Bubble Machine Application Guide

Sound Bubble Machine Application Guide Rendering pictures information: Software: EASE 4.3. Subwoofer Data: RCF TTS26-A (GLL), double 15”, preset: 30-160Hz. Direct Sound Pressure Level rendering is calculated at 100Hz, 3 octave bandwidth sum.

Omnidirectional at Low Frequency Two subwoofers, located at left and right of the stage. Sound radiates omnidirectional to all direction.

Cardioid Array Cardioid array setup using two subwoofers (each side), 70cm spacing.

Cardioid Array Low frequency sound is directed to the audience, less spill to the stage area.

Cardioid Array

Cardioid Array Same configuration, but stacked.

Cardioid Array Same configuration per side, using two subwoofers facing forward (no delay, in polarity) and one facing backward (with delay, out of polarity).

Forward Steering Forward Steering with 80cm spacing between subwoofers.

Forward Steering Delay Ratio: 100%

Forward Steering

Forward Steering Forward Steering with 80cm spacing between subwoofers. Delay ratio: 150%.

Forward Steering Delay Ratio: 150%.

Forward Steering Forward Steering with 80cm spacing between subwoofers. Delay Ratio: 50%.

Forward Steering Delay Ratio: 50%.

Electrical Steering Five subwoofers in the middle arena (above the main stage) in a straight array.

Electrical Steering Electrical steering to aim the main sound lobe 15deg upward, more to audience area.

Electrical Steering Using delay time calculated to aim the sound lobe 15deg upward.

Electrical Steering

Curved Array Five subwoofers in a straight array (1.5m spacing between subwoofers) in the front of the stage.

Curved Array Adding delay to the straight array to create an imaginary curved array (90deg arc).

Curved Array Straight array with delay to create an imaginary curved array (90deg).

Curved Array

Curved Array and Cardioid Array Adding subwoofers and extra delay to combine curved array and cardioid array configurations.

Curved Array and Cardioid Array Straight array with delay to create an imaginary curved array (90deg), combined with cardioid array with 80cm spacing to the back subwoofer (out of polarity).
