How to determine a speaker's thread size

1. Use our Product Selection Calculator

When you use our Product Selection Calculator not only will you get the recommended IsoAcoustics product for your speaker, you will also be able to see the common thread sizes used by your speakers’ manufacturer. The calculator will also specify if the threads are included with the recommended GAIA model, or if they are supplied separately.

2. Send us your photos so we can help

Remove an existing spike/foot from your speaker. Using a ruler or tape measure, submit the following photos to threads@isoacoustics.hu for review. The tape measure can be in Metric or Imperial. Please include your name and the make & model of your speaker or component in your email.

1. Thread Diameter
Position the ruler (metric/imperial) so that it is raised to the mid-way height of the thread (the widest section). Take photo from above with good lighting and threads in focus.

2. Thread Diameter
Position the ruler at the end of the thread, and so that it is raised to the mid-way height of the thread (the widest section). If the ruler cannot be positioned at the end of the thread, submit photos of the ruler positioned behind the thread and in front of the thread.

3. Test existing spike/feet at hardware store or with thread checker

Remove existing spike/foot from speaker and the test the thread size using a thread checker. Thread checkers are available for use at most hardware stores or are readily available for purchase.

4. Contact Manufacturer

Submit an inquiry to the speaker manufacturer requesting the thread size for your model of speaker.

How IsoAcoustics thread adaptors work

Each GAIA thread requires 2 lock nuts:

The upper lock nut is tightened up against the bottom of the speaker.
The lower lock nut tightens up against the top of the GAIA housing.

The GAIA thread adaptors have 2 sides:

Side 1 is installed into the base of the speaker. The thread size of Side 1 matches the speaker thread size.
Side 2 is installed into the GAIA housing. The thread size for Side 2 matches the thread size of the GAIA housing.
