Build Format

The classic ES18 BHP, Electrikal version. Modified from the original to have a front face of 636x636mm, this cabinet now fits perfectly on top of Hogs.

Offering the same clear, precise bass projection as the initial design by Stipe, the ES18 is a very well renowned midbass / kick cabinet.

Suggested to be run from around 55hz - 180hz depending on your choice of driver. If you order a kit or unloaded cabinet, please leave a note in the checkout process of what bolt pattern and driver cutout you require.

These cabinets / kits are built to order, so please allow for a 8-10 week lead time.

Intermediate. Some cabinet building experience is recommended. Moderate build complexity, a reasonable number of parts, potentially including subassemblies.
