Build Format

The cult classic, the HD15. This is the standard cab that everyone knows and loves - simply built well. Well done on this one Rog!

This cabinet offers a classic horn loaded sound for kicks, based around a 15" driver. Built with a 4-panel curve.

Providing midbass from around 55hz - 180hz depending on what driver you use, this is a versatile cabinet.

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

If you're purchasing a flatpack kit, please be sure to check the difficulty levels and advice in the dropdown sections below.

Features and Applications

This is a midbass / kick cabinet. It offers powerful, precise midbass. We recommend you run it in the region of 55hz - 180hz.

Flatpack kits include

  • All panels, cut from 18mm Birch plywood
  • All the screws you need
  • All the bolts and insert nuts you need
  • Gasket tape for the access hatch
  • Wadding
  • A pre-wired NL4 speakon dish, with gasket

Flatpack kit build difficulty

Intermediate. Some cabinet building experience is recommended. Moderate build complexity, a reasonable number of parts, potentially including subassemblies. The order of assembly requires some thought and has only a few ways to build the kit. You need a drill / impact driver and glue. You may find clamps or a nail gun would be useful as well.

Acoustic Specifications

Exact acoustic specifications change depending on what driver you put in this cabinet.

We recommend the Eminence Kappa 15LF as a good budget option. This is what is in the Standard Loaded cabinet.

For greater power handling and output, we suggest the RCF LF15X401. This is what is in the Premium Loaded cabinet.

  • 18mm Birch plywood used throughout - 100% NON Russian plywood is used throughout our products, all timber can be traced back to the mill of origin.
