To achieve the best possible performance from your Lithe Audio speaker, correct installation is just as important as the speaker itself. One of the most critical factors is the enclosure (back box) volume.

The Ideal Back Box Volume: 13 Litres

For optimal sound quality, bass response, and overall balance, the ideal enclosure volume is 13 litres (13L).

This volume has been carefully engineered to:

1. Deliver controlled, punchy bass without boominess
2. Maintain clarity in vocals and mid-range frequencies
3. Prevent distortion at higher listening levels
4. Ensure consistent performance across different room types
   

No Fixed Dimensions – Volume Is What Matters

There is no predetermined width, height, or depth for the enclosure. As long as the internal volume equals 13 litres, the speaker will perform as intended.

This gives installers and designers complete flexibility to:

1. Fit within ceiling voids or stud walls
2. Work around joists, pipes, or other obstructions
3. Custom-build enclosures to suit different installation environments

For example, a shallow wide box or a deeper narrow box will both work perfectly, provided the total internal air volume is 13L.

What Happens If There’s No Back Box?

While the speaker will still operate without a back box, sound performance can vary depending on the ceiling cavity size. This may result in:

1. Excessive or uncontrolled bass
2. Reduced clarity
3. Inconsistent sound between rooms

Using a correctly sized 13L enclosure ensures predictable, repeatable, and professional-grade audio performance.

Installation Tips for Best Results

Measure internal volume, not external dimensions

Allow for speaker displacement when calculating volume

Ensure the enclosure is well-sealed to prevent air leaks

Use solid materials (e.g. MDF) to minimise resonance

In Summary

✅ Ideal enclosure volume: 13 litres

✅ No fixed dimensions required

✅ Volume consistency = sound consistency

✅ Flexible installation with professional results

By simply ensuring a 13L back box volume, you’ll get the very best sound your Lithe Audio speaker is designed to deliver.
