Audio & Acoustics Stiff, light domes for clear treble
High-frequency loudspeakers need rigid, low-mass diaphragms. Diamond domes are designed for that duty.
Where diamond helps
Diamond is used in audio and acoustics for tweeter domes, because its stiffness relative to its mass pushes break-up resonance higher. Buyers specify dome diameter, curvature, wall thickness and rim attachment. Sound quality depends on the whole driver, including suspension, motor and enclosure.
The challenge
Dome break-up
Flexible diaphragms vibrate unevenly at high frequency, which colours the sound.
Moving mass
A heavier dome reduces sensitivity and high-frequency extension.
Fitting to your driver
The dome must match your voice coil, suspension and mounting interface.
How diamond helps
Thin diamond diaphragms
Diamond speaker domes, from Acoustic Components, are thin, curved diaphragms for high-frequency drivers.
Specified to your driver
You define diameter, curvature, thickness and rim; we review them against your design.
Validated as a driver
We agree evaluation with you, because dome material alone does not set bandwidth or sound quality.

Common questions
Why use a diamond tweeter dome?
Diamond is very stiff for its weight, so a dome can move as a single piston over a wider frequency range. The benefit depends on suspension, motor and enclosure. Evaluate the complete driver.
What do you need to quote a speaker dome?
We need diameter, curvature, wall thickness, moving-mass target, rim attachment and the frequency response you want. A drawing helps. We will confirm what can be made in technical review.
Can I order sample domes for testing?
Paid evaluation samples are available where appropriate, scoped to your evaluation. Tell us your driver design and test plan, and we will advise on what to evaluate.
