Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...
Sixteen ohm drivers (or loudspeakers systems) would be connected to the 16-ohm tap, 8 ohm to the 8 ohm tap, etc. This is significant since the ratio between the loudspeaker impedance and the amplifier's impedance at a particular frequency provides damping (i.e., energy absorption) for the back EMF generated by a driver.
In the late 1940s, horns whose mouths took up much of a room wall were not unknown among hi-fi fans. Room-sized installations became much less acceptable when two or more were required. A horn-loaded speaker can have a sensitivity as high as 110 dB at 2.83 volts (1 watt at 8 ohms) at 1 meter. This is a hundredfold increase in output compared to ...
The NS-10 is an 8-ohm two-way loudspeaker with a 10.4-litre sealed cabinet measuring 382 × 215 × 199 millimetres (15.0 × 8.5 × 7.8 in) and weighing 6 kilograms (13.2 lb). [5] [4] Its 2.5 cm (0.98 in) particle-board cabinet has a wood veneer skin with seven black finishing layers. The domestic version of the speaker was vertically oriented ...
Subwoofers: These speakers are designed to reproduce low-frequency sounds, particularly bass. They come in various sizes and power levels, and can be used to enhance the bass in a car audio system. Mid-range speakers: These speakers are designed to reproduce mid-range frequencies, such as vocals and instruments like guitars and pianos.
[citation needed] High-power in-car audio systems using 2-ohm speaker circuits require thicker wire than 4 to 8-ohm home audio applications. Most consumer applications use two conductor wire. A common rule of thumb is that the resistance of the speaker wire should not exceed 5 percent of the rated impedance of the system.

However, some speakers require an amplifier with a low damping factor to reproduce rich, full-bodied sound. The E-202 has a Speaker Damping Control which permits choice of three damping factors and induces maximum potential performance from any speaker. Damping factor with an 8 Ω load becomes more than 50 when this control is set to NORMAL ...
