From background music in your business to foreground music in your bar or restaurant, ADI has the solution.

Music in your business can either be background or foreground. Background just means that the volume level will never be very loud so it's more in the background. Foreground means that it is a primary means of sound and needs to be able to play at a fairly loud level. This would usually be in a bar or restaurant, but there are also reasons for this in other types of businesses. Either way, there are similarities between them and ADI can help!

We have many different systems and designs for you! Call ADI today for a free proposal or read on for more information.


Speakers would typically be mounted in the ceiling for background music. They could be just a single full range speaker on the low end or a Coaxial speaker where you have a woofer for the low frequencies and a tweeter for the high frequencies. Coaxial speakers sound much better but cost more money than a full range speaker. In foreground music applications, you would typically use a stack of speakers or hang them on the wall or from the ceiling.


In most cases, the in-ceiling speakers would not be able to do a great job on the very low frequencies (bass). This is because to reproduce low frequencies, you need a big speaker and a box behind it. There are companies that make in-ceiling subwoofers, or we could build a subwoofer in to a wall or under a stage or seating to be able to generate the lowest frequencies. For background music, many times a Subwoofer is not necessary.

Power Amplifiers

To power the system, you could either use normal power amplifiers or a 70 volt system. 

  • 70 Volt-- A 70 volt system is usually only used for low-end background music. The system puts out a constant 70 volts and each speaker has a transformer and a tap setting so you can adjust how loud each speaker will play.
  • Standard Power Amplifier-- Here you would use one or more standard power amplifiers and some type of device that would match the impedance to the amplifier. The impedance matching could be done in a switching type device or in an impedance matching volume control. So the idea is that you have to present a 4 or 8 ohm load to the amplifier and the impedance matching device will take care of that for you. This will ensure that you don't damage the amplifier.
