Not all subwoofers require the same size opening; for example, the JL W7 Series cut-out requires a different size opening from the standard. Our enclosures come with round standard size openings;
- 8” – 7 1/8”
- 10” – 9 1/8”
- 12 – 11 1/8”
- 15” – 13 7/8”
**Custom openings are available for an up-charge
