Gravitas Subwoofer


Please Read - Important Delivery Information

Collections: Subwoofers

Type: Subwoofer


It is difficult to express how awesome the new Gravitas is.  Normal specifications do not properly describe the effortless power, weight and authority it can deliver.

To frame the immense capability of the Gravitas in another way, when played to capacity reproducing the lowest
note on a four string bass, each Gravitas will displace 18,000 litres of air in under 60 seconds.

Considerably smaller and more flexible than the famous  VAF MPB SW19, the Gravitas features two 330mm woofers (one at each end) along with two digital processor and amplifiers, one for each woofer. This allows perfect setup even if placed off centre in a room where each woofer in each enclosure may be a different distance from a listener. This makes it possible to independently align the phase, level and blend frequency of each woofer with the respect to the listener. This is a first for any commercial subwoofer.

Alongside the obvious application for serious home theatre, for audiophile stereo lovers there is a high pass filtered output making Gravitas an active crossover easing the bass burden and distortion of the loudspeakers with which it is paired.

VAF claim great pride in attention to detail. That’s why inside the substantial 47Kg Gravitas there are five internal partitions ensuring no
external panel is unsupported over a span greater than 130mm.  The result is Gravitas’ amazingly inert resonant free enclosure.

To put it simply, in a market full of ‘me-too’ subwoofers,
VAF Research the new VAF Gravitas stands alone.

Phase Optimisation

As the intention of the Gravitas is to redefine subwoofer quality, VAF has for the first time ever in a commercially available subwoofer, made it possible to adjust the phase, frequency and output of each individual woofer within each Gravitas subwoofer. This enables the fussiest of listeners to optimise the sound perfectly, even taking into account the small difference in distance between the listener with respect to one woofer verses the other.

Unity Gain buffered Daisy Output

All VAF subwoofers feature both inputs and outputs to allow daisy chaining to create multi point bass systems.   This enables 2, 3, 4 up to 10 subwoofers to be used in the same system. So whether they are used in twin subwoofer MPB systems, right through to total MPB offering one subwoofer for each channel, the line level electrical connection is efectively perfect..

Multi Point Bass (MPB)

VAF’s Multi Point Bass (MPB) radiates bass into a room with controlled dispersion in a way that blends perfectly with the main speakers in either surround sound and stereo movie or music systems. An additional benefit of MPB is more even bass across a whole room which is not just limited to a ‘sweet spot.  The buffered unity gain outputs on all VAF subwoofers makes them natively designed for MPB.

Digital Dymanic Engine

VAF Programable DSP (Digital Signal Processing)
Multi Layer Digital Compression Minimiser
Variable Phase Optimisation

Active Stereo Integration

Unlike other subwoofers intended solely for home theatre, all VAF subwoofers include Digital High Pass filters that enable the subwoofers to become part of a high fidelity stereo system.

Native Room Optimisation

Subwoofers are able to add a foundation of bass to deliver the full lower frequency sounds in both stereo and surround sound systems. While a single subwoofer can add the ‘weight’ to the sound, a single subwoofer can never be integrated perfectly with either stereo or surround speakers.
