The price gap, with the math
The 55X is our lead kit, and the 109mm King 55X at $549 is the like-for-like anchor, because all three rivals sell 109mm. Against it, on Oct 25, 2026, King Kone V2 lists for about 3.7 times, Knockbox 50 (sale price) about 5.0 times and RollCraft MRB about 6.4 times the price. At entry level, against our $369 19-cone kit, the same three list for about 5.6 times, 7.4 times and 9.5 times.
| Rival (price read Oct 25, 2026) | Price | ÷ $549 (109mm King 55X, lead kit) | Multiple | ÷ $369 (19-cone entry kit) | Multiple |
|---|---|---|---|---|---|
| King Kone V2 | $2,049 | 2,049 ÷ 549 = 3.73 | 3.7x | 2,049 ÷ 369 = 5.55 | 5.6x |
| Knockbox 50, sale | $2,749 | 2,749 ÷ 549 = 5.01 | 5.0x | 2,749 ÷ 369 = 7.45 | 7.4x |
| RollCraft MRB | $3,500 | 3,500 ÷ 549 = 6.38 | 6.4x | 3,500 ÷ 369 = 9.49 | 9.5x |
Futurola's page also shows a regular price of $3,749 for the Knockbox 50, read Oct 25, 2026. No multiple is attached to it.
Price per cone slot is price ÷ cones per run. It shows what each cone of capacity costs, and the 55X and 19X kits fill fewer cones per run than King Kone does.
| Machine | Price | Cones per run | Price per slot |
|---|---|---|---|
| Humboldt Filling Machines 70mm 55X kit | $449 | 55 | $8.16 |
| Humboldt Filling Machines 84mm 55X kit | $469 | 55 | $8.53 |
| Humboldt Filling Machines 98mm Classic 55X kit | $499 | 55 | $9.07 |
| Humboldt Filling Machines 109mm King 55X kit | $549 | 55 | $9.98 |
| Humboldt Filling Machines 109mm 19X kit | $369 | 19 | $19.42 |
| King Kone V2 | $2,049 | 169 | $12.12 |
King Kone V2 is $12.12 per slot, which is lower than our 19-cone kit at $19.42. From the 55-cone kits up, ours is lower: all four 55X kits run $8.16 to $9.98 per slot. Knockbox 50 and RollCraft MRB are left out of this table because their cones per run are not verified here. See futurola.com and rollcraft.co.
