NOVA 2 - Building Instruction            Nova 2- Overview   Lab Results

The cabinet should be built with either MDF or multiplex boards. For further quietening of the cabinet, 4 mm Bitumex boards may be attached to the inside walls - although it didn't seem necessary to us.

The Nova 2 is an extremely slim speaker; to prevent the cabinet from tipping over a base plate needs to be screwed to the bottom panel.

1 bag of polyester damping material should be placed into the small, upper chamber. The remaining damping material should be loosely packed in the lower chamber, the bass reflex tubes (and 15 cm around them) should remain uncovered.

Nova 2 Gehäuse It's best to start with one side panel, the second side panel should be attached last.

All panels need to be screwed together; lastly, the drivers will be fitted.

The bass reflex tubes consist of two parts, shortened to 125 mm and then glued to one another back-to-back. Before fitting the last panel the bass reflex tubes should be pushed through the reflex opening. Two tubes each should then be glued together - it cannot no longer be done afterwards.

The crossover may be placed on the bottom panel; the base should the be detachable.

Before fitting the second side panel all internal wiring should be completed; afterwards it's considerably more complicated.


Nova 2: the crossover

The crossover components should be either hot-glued to a wooden board or attached with cable fasteners and the wired up. If preferred, a universal PCB may be used where the components are fed through one side and soldered on the other. Nova 2
If a valve amp is being used we recommend a serial resonance circuit for impedance correction. Components to be used:
- ELCO unetched 33 uF
- air core coil 0.15 mH / 0.7 mm
- resistor 4.7 Ohm 10 Watt
All components to be wired in series, the two leads to be connected to the loudspeaker terminals.
Although connection is easy, contact us if you need help.
