Before you buy — quick checklist

Confirm your existing speaker cutout diameter is 4 inches before ordering
Verify this is an OEM Dynasty Spas audio system — this is not a universal-fit speaker
Check that your spa's audio system impedance matches this speaker's rating
Inspect the speaker wire connections at the amp for corrosion before swapping the speaker — a bad connection can mimic speaker failure
Confirm the mounting depth clears your spa cabinet framing

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
