Sound System

Tried and tested touring sound system

Since 2009. Thanks to the cyclists!

Reaction Sound System

Really Sensitive Sound.

Efficiency is nothing without sound quality. If the sound system sounds bad you can’t just use more power to make it good. There is a difference between “loud” and “good”. With good audio engineering, a badly built or designed sound system can be made to sound much better, but a PA system can be loud and good without needing much power. Designers and engineers know compromises must sometimes be made. But for us a sound system needs to be able to reproduce the low note on a bass guitar. Commercially available speakers weren’t up to the job. We needed sensitive (efficient) speakers. Not commercial squeekers!

We built up our sound system over the years from Fsc certified birch Ply right here in Leeds Yorkshire (home of some big sounds) and over the years it has done brilliantly.

We hire the sound system with or without the bike generators and can power it entirely from bike-power or with solar power or even entirely from the mains. Either way you get the benefits of reduced power consumption and stadium style high quality line array speakers. We have a crew of excellent Djs and engineers so your event can run smoothly and with a relaxed positive atmosphere. We are all about pleasant sound and low bass. We want the right volume. No ego competition and ear splitting screeching tops. We care for the planet and peoples hearing.

There are lots of variations in the design of loudspeakers. Even though they all look boxy on the outside there can be some complicated shapes inside. These shapes, like the horn of a gramophone, serve to amplify the sound.

while some manufacturers do produce efficient speakers commercially, Many commercial manufacturers prefer simple designs because they are faster and cheaper to produce and although sound quality and efficiency are compromised they can make up for that by adding bigger amplifiers. This has lead to a kind of inflation of power use. Unfortunately almost everyone uses the maximum power rating of the speaker/amplifier to quantify sound systems. Eg “its a 10k rig” (i’ve even seen 100,000kw advertised!)

In the old days of the dawn of large scale amplified music events the largest amplifiers available were 100watts. Masses of work was put into designing loudspeaker enclosures which maximized the sound pressure level (SPL (measured in Db (decibels)) possible with these small amplifiers.

All of this technology is still available but while sound systems continue to be measured in KW(power) not Db (actual volume) there will always be a pressure on sound systems to adopt inefficient speaker designs so they can appear louder to event organizers. Events often get larger generators than they need meaning the generator runs outside of it’s ideal range for efficiency. Powerful thinking are working investigate how better use of diesel generators and burning reused veg oil can also reduce the greenhouse impact of small events.

The downside of efficient horn type loudspeakers is they are often larger and heavier than their basic reflex counterparts. Plus they take more time and skills to build and engineer properly.

The speakers we use are compact coaxial horns and are arrayed in a vertical line array of the type used in stadiums and at really large events. They are great for outdoor use and for large venues as they focus the sound down to where you need it. The towers we use to raise the speakers above head height allow relatively uniform sound coverage as the speakers are not just pointed directly at the front row. We have 4 different sized setups to cater for smaller and difficult acoustic conditions.

At most events in the uk there is a restriction on how loud you can have a sound system and we generally find it easy to reach that level. We comfortably reach 99db (at FOH) which is about the right volume as a compromise between too quiet and permanently damaging the hearing of the crowd/ bothering the neighbors!

We use digital amplifiers which have a much greater efficiency at all output levels. Our bass amplifer is 2.500watts max power and we drive our mid tops with up to 650watts a side. But we normally use less power than that. We are working on integrating power measurement into our systems to help give the actual figures at your event in the future.
