The Faya rig has changed soundystem culture forever...

The new Faya Sound has revolutionised Sound System culture……. It Sounds beautiful with both digital & analogue input. It fits in a car and one man can assemble it and operate it. The barriers to entry for sound system culture spreading have always been transport and storage. To run a sound you need a lock up and a van. People can’t really afford those things on top of paying for the sound……Faya Sound has changed all that forever.

Nothing packs as much punch with such a small footprint!

It’s amazing. It has a level of transient detail, separation, speed and responsiveness that is leaps and bounds ahead of most ‘reggae friendly’ sound system units. The driver and cab combinations are meticulously paired and engineered to get the most out of their relationship. It has enough accuracy to work as a stereo pair left and right of a stage and have a band engineered through it. It has a studio like quality to its sound. Although very weighty bass, it lacks slightly in the lowest notes, so would not work so well for extremely low digi basslines or for other genres like dubstep that rely on the 30hz range.

That said, it would still work well, it’s just better on basslines in higher octaves. It could play lower frquencies the more scoops that are coupled together. Its portability is insane (although I only carried the neo version) even ferrite would still be ok if people were on lower budget. Setup and pack down are a breeze, the system stacks amazingly due to the locking stacking system, both keeps the stack secure and ensures that the boxes are positioned correctly according to the alignment presets that are provided with the rig or pre-loaded in the DSP (if you buy with amp). The finishing is very good and the custom grills are a beautiful touch.
In the test run we had noise complaints almost immediately, which proved the bass was weighty, but more importantly, I told the team that with a low volume I might cut my set short because it would be hard to hold the energy for the 3 hours I was scheduled to do the live mix, but as soon as I started, the level of detail and clarity was so much fun to play on I played all the way through and was able to be unusually creative in my mixes because I could actually hear myself in the full context of the space for once.
Overall I think this product will fundamentally change the game!
