Summary
From the perspective of earthquake resistance, the thicker the material, the better.
But the speaker production should design the cabinet according to the size of the speaker and the resonant frequency.
The thickness of the speaker cabinet walls of each material is different and it is critical to the quality of the sound.
Types and Functions of Speaker Cabinet
The common speaker enclosures materials are wood (solid wood, MDF), plastic (PP/ABS/Acrylic), metal (steel or aluminum alloy), etc.
From the perspective of earthquake resistance, the thicker the material, the better.
But the production should design the cabinet according to the size of it and the resonant frequency.
The thickness of the cabinet walls of each material is different and it is critical to the quality of the sound.
Thickness Design Can Reduce Resonance and Make The Sound Pure
Material thickness and quality directly affect the cost and performance of speaker products.
The thicker the enclosure wall, the less vibration the cabinet will generate when the sound is emitted, especially for active systems with high-power amplifiers.
Please refer to the list below for common thicknesses:
Wooden speakers: 5-30mm, mainly 10-20.
Plastic speakers: 3-20mm, mainly 3-8mm.
Metal speakers: within 5mm.
The Thickness of The Speaker Box Wall Affects The Bass Effect
To a certain extent, the thickness of the board is a strong guarantee for the realization of the subwoofer effect.
Therefore, the thickness of the wooden speaker shell will be thicker than that of plastic and metal ones, and its bass effect will be better.
Example from AUSMAN Audio Cases
One of AUSMAN Audio's customers from the Middle East always complained that our price is higher than other suppliers for the same model they need.
After the analysis, we found the reasons for the price difference.
One of the reasons is the thickness of the cabinets of the speaker.
This is a 2.0 DJ system pair (12" Floor Bluetooth Standing Speaker), the box material is MDF wood.
The shell thickness of AUSMAN Audio MDF products is 15mm, and our competitor is 11mm.
In terms of enclosures, we are $10 more expensive than our competitors, but we use thicker panels, which effectively reduce resonance and ensure bass.
But the biggest difference is bass performance.
This customer did an experiment with all the prototypes.
When the volume was turned up to 80%, he found that the resonance of the 11mm prototype was very serious, and our prototype did not have similar problems when turned up to the maximum.
Great Sound Comes From Great Design
A high-quality speaker is the precise design and grasp of every detail by the manufacturer.
The thickness of the box wall is an important factor affecting the sound performance.
It also includes chips, PCBs, power amplifier boards, frequency dividers, wires, speakers (paper cones or polypropylene speaker cones), frequency response curve settings and other factors.
The Thickness of Cabinet Walls is Critical To The Sound Quality
A high-quality product is a whole of good design in its individual parts, including of course the thickness of the speaker cabinet walls.
This requires manufacturers to have independent design capabilities and long-term manufacturing experience.
Thickness design will vary by types, usage and sound requirements (wooden/plastic/metal/active/passive/portable/outdoor).
For example, indoor audio pays more attention to sound quality performance, and the thickness will be thicker, so the wooden boxes will be the better choice.
Outdoor portable models are required to be lighter in weight, and thinner and lighter plastic shells are often used.
