• General note on the 8-ohm impedance: Some speakers work internally with 4 ohms and achieve the 8 ohms at the connection by an additional 4 ohm wire resistor (usually with an angular ceramic coating) at the connection.
• I don't know if this is also the case with this model. If you have a 4-ohm-capable amplifier, you can convert such boxes: unscrew the bass speaker, bridge the series resistor and change the impedance on the nameplate to 4 ohms (changing the nameplate is important because a 4-ohm box can overload an amplifier with a minimum impedance of 8 ohms, e.g. Mitsubishi DA-R45P and DA-R47P).
• The advantage is that an amplifier performs more at 4 ohms than at 8 ohms.
• As I said, the disadvantage is that the box can then no longer be connected to all amplifiers.
