What Size Speaker Box Do I Need?

Key Takeaways

  • The box size follows the cabinet plus two things people forget: the accessory layer and the cushioning. Measure the cabinet over grille and feet, then add the accessory block and about 1 to 2 in of cushioning per face depending on weight.
  • Portable units usually pack in a carton close to the cabinet with a die cut tray. Bookshelf and floor standing cabinets need corrugated end caps and, above a certain weight, double wall board.
  • Packing a stereo pair in one carton needs a centre divider, and it makes one heavy parcel instead of two, which can cost more to ship than it saves in cartons.
  • Speaker cartons start at a minimum of 100 boxes, from about $0.48 per unit at bulk volumes on a written quote, with the die, plates and a digital proof included.

Speaker cartons are sized by category more than by clever measurement, because the failure modes differ so much between a pocket unit and a floor standing cabinet. Find your category, then apply the accessory and cushioning allowance.

Three numbers to send us

  1. Cabinet dimensions at the widest point of each axis, with the grille on and the feet fitted.
  2. Loaded weight of the complete pack, since weight decides the board grade and the cushioning depth.
  3. The accessory list, measured as a block: power supply, cables, remote, manual, spare grille.

Those three are enough for us to propose a carton, a tray and a lane. Everything else can be settled on the dieline.

Where the extra inches come from

A common surprise is that the finished carton is several inches larger than the cabinet on every axis. That comes from three places: cushioning against drops, the accessory layer, and the board itself. A double wall corrugated wall adds real thickness, so state internal dimensions and let us calculate the external ones. If the external size matters because of a carrier band or a shelf, tell us the external limit and we will work inwards from it.

One carton or two

Packing a stereo pair together looks efficient and often is not. One carton means one die, one print run and one label, but it also means a heavy parcel that may cross a carrier weight band, and a total loss if that parcel is dropped. Two cartons cost more in materials and less in damage. If the pair is sold as a set and mostly ships by pallet, one carton usually wins. If it mostly ships by courier, two usually does.

Ordering

The minimum is 100 boxes, with pricing from about $0.48 per unit at bulk volumes confirmed on your written quote. The die, plates, design support, US shipping and a digital proof are included, so a tray or end cap cut around your cabinet costs no more to tool than a generic one. Turnaround is quoted per job in three lanes, rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days, plus 2 to 5 for delivery, and specialty imported constructions can run up to about 12 weeks.
