Unity Audio The B.A.B.E. (Boulder Active Bass Extender)

Bass – how low can you go?

The B.A.B.E. transforms the existing 3-way Boulder into a true 4-way monitoring system. With flexible soffit mount or free-standing installation options, the system can be mounted horizontally or vertically. An optional free-standing plinth/spacer is also available.

The 4-way system extends SPL and frequency response.

The sealed cabinet is internally isolated to reduce vibration interference and uses a single 300mm driver with a 125mm voicecoil, designed exclusively to low frequency reproduction.

The System

The system comprises two bass extension cabinets with their own rack mountable 750 watt class D amplifiers and speaker-management. All housed in separate rack mountable units that control all the audio routing, gain, cross-over management, optional EQ and Limiting.

BB-DSP Processor

With 4 balanced analogue inputs and 8 outputs with full matrix mixing capabilities, the Unity Audio BB-DSP gives the flexibility you need to control 2x B.A.B.E cabinets and Boulders, or even 4x B.A.B.E’s and Boulders for larger systems, or a L,C,R B.A.B.E/ Boulder for surround configurations. Compressors are available on every input as well as a high pass filter, 6 bands of parametric EQ and up to 1.3 seconds of delay.

The BB-DSP comes with a factory configured preset with the correct 167Hz Linkwitz Riley 24 dB per octave crossover, ganged outputs 1 & 2 feed the B.A.B.E’s, with ganged outputs 3 & 4 feeding the Boulders. A second preset is also provided effectively acting as a B.A.B.E bypass if required to use the Boulders by themselves with their original full frequency response.

Every output channel has high and low pass filters, 8 bands of parametric EQ, up to 1.3 seconds of delay as well as a new limiter designed to offer the best driver protection with the lowest distortion.

The BB-DSP runs at 96kHz as standard but can be switched into 48kHz mode to take advantage of 48dB/oct output crossover filters and two bands of dynamic EQ on both input and output channels.

The ethernet based PC control software gives you the ability to not only control all the devices on a network but also to store preset memories and configure systems offline.

Drivers

The B.A.B.E. uses an innovative 300mm woofer designed exclusively for sub and low frequencies. The driver employs a huge 130mm Hexatech external voice coil wound with a hexagonal-shaped aluminum coil wire (2-3 times thicker than standard woofers) for accurate music reproduction, superior durability and power handling. This driver delivers an extraordinary combination of audiophile musicality and high power handling.

The B.A.B.E. adds a flexible modular approach enabling a fully 4-way system configured the way you want it, with breathtaking performance.

Sealed cabinet

The B.A.B.E. retains the same sealed cabinet approach used throughout the Unity Audio range. This design approach provides faster, tighter and more accurate linear bass reproduction and results in less phase rotation, reduced time domain ringing, lower group delay and a shallower roll-off slope than inferior ported designs. These characteristics make The B.A.B.E. a natural choice for all critical music applications.

Flexibility

The B.A.B.E. is suitable for all recording and mastering facilities and has been carefully designed to suit all environments and applications.

The system can be used free standing or soffit mounted in either horizontal or vertical configurations without compromising performance.
