Enclosure Configuration Controls

How enclosure type, volume, tuning, ports, passive radiator settings, and baffle-step settings affect simulator results.

Direct answer

Enclosure configuration controls define the acoustic loading and front-baffle assumptions that turn one driver into a sealed, vented, passive-radiator, or bandpass system.

What it measures

• Enclosure type and volume.
• Tuning frequency, port geometry, port count, and end corrections for ported designs.
• Passive radiator selection, count, and added mass for passive-radiator designs.
• Optional baffle-step dimensions, driver offset, transition frequency, depth, and smoothing.
• Derived build values such as port length and tuning-related summary fields.

Why it matters

• Small changes to volume or tuning can change extension, excursion, group delay, and port demand.
• Port and passive-radiator settings can make a simulated alignment practical or impossible.
• The same driver can behave very differently across enclosure types.

How to read it in 00 Simulator

• Start with enclosure type and volume before interpreting graph changes.
• For vented designs, check the calculated port length and velocity together.
• For passive-radiator designs, check PR excursion after changing added mass or radiator count.

What good, warning, and bad usually look like

Good

The geometry, tuning, and result limits all support a buildable design.

Warning

A response improvement comes with a port, excursion, or tuning tradeoff that needs confirmation.

Bad

The configuration produces non-buildable dimensions or pushes physical limits before meeting the design goal.

Common false conclusions

• A theoretical alignment is not automatically buildable.
• Changing volume to improve F3 can worsen excursion, group delay, or enclosure size constraints.
• Port diameter, count, and length must be considered together.

App behavior notes

• The guide currently documents sealed, vented, and passive-radiator workflows in more detail.
• Vented port length can be calculated from target tuning or back-calculated from a fixed physical length in the app.
• Baffle-step settings are shared with the Baffle Layout tile and are stored on the enclosure.
