Alcone Midi: Building Instructions

Alcone Midi

The Mini's cabinet may be built either from solid 19 mm MDF or multiplex board. Considering its size this cabinet is exceptionally rigid, stiffened even more by 2 additional bracing panels.

The edges of the cabinet's baffle should be slanted or rounded.

Should the cabinet be positioned against a wall, the bass reflex tube may also be mounted beneath the bass driver (below bracing panel) pointing forward; in this case the tube should not be shortened.

The recess depth for the tweeter should be 3 mm or 6 mm, in which case 2 layers of sealing tape or 3 mm cardboard should be used.

The cabinet should be damped with one pack of polyester fleece, to be placed from the centre upwards.

Alcone Midi: Crossover

The crossover components should be either hot glued onto a wooden board or attached with cable fasteners and wired afterwards. Alcone Midi Frequenzweiche

If a valve amp is being used we recommend to adjust the impedance by installing a serial resonant circuit with the following components:
- 12-Ohm resistor MOX 10 (brown-black-black),
- 0,82 mH air-core coil, 0,7 mm
- 15 μF electrolytic capacitor, smooth
All components need to be connected in series, the two ends will be connected to the loudspeaker terminals.
