Recommended Amplifier Size

The following table shows the recommended power amplifier size, in watts, for each iBOX model.

Table 9: Recommended Amplifier Size

* iBOX three-way models use the internal mid-high passive crossover in bi-amp mode.

iBOX Subwoofer - Powering Each Woofer Separately on Dual-Woofer Models

Depending on the amplifier used, the best way to get maximum power to an iBOX dual-subwoofer model may be

to power each woofer separately from a single amplifier channel.

To do this, remove the connector panel and cut the red and black jumper wires on the PC board. Then replace

the connector panel. Normally, the NL4 1

terminals are paralleled with the 2

terminals. Now, one woofer is

connected to the NL4 1

terminals and the other woofer is connected to the NL4 2

terminals.

For best results, the two amplifier channels should feed exactly the same power to each woofer and the woofers

must have the same polarity. Some amplifiers feature a “parallel” mode that makes this easy. In this mode, you connect
the source to one channel and the amplifier feeds exactly the same power to both outputs.

If you cut the jumpers on a single-woofer model, the NL4 1

terminals continue to power the woofer. The 2

terminals are looped through to the 2

terminals on the other NL4 but are no longer connected to the woofer.
