Alcone Laplace XT: Building Instruction

The cabinet should be built with 19 mm MDF or multiplex boards.

2 bag of polyester damping material should be placed in the upper and lower part of the cabinet. The bass reflex tube should remain uncovered. Alcone Laplace XT

Laplace XT: Crossover

The crossover components should be either hot glued onto a wooden board or attached with cable fasteners and wired afterwards. A universal PCB could also be used, where the wires of all components are fed through the PCB and soldered on the other side. Alcone Laplace XT
If a valve amp is being used we recommend to adjust the impedance by installing a serial resonant circuit with the following components:
- Electrolytic capacitor, unetched 22 μF
- Air-core coil 0.68 mH / 0.7 mm
- Resistor 10 Ohm, 10 Watt
All components need to be connected in series, the two ends will be connected to the loudspeaker terminals.
