Tie rod speakers
Tie rod speakers do outdoor publicity or dancing is better, singing sound quality is not as good as KTV speakers - because this speaker amplifier is not HiFi sound - is a low-voltage battery-powered - is a more backward type of amplifier, and it is a monaural (only a woofer and tweeter) the sound quality is a little bit poorer, so it is only suitable for doing outdoor publicity or square dancing, so it is not good. Singing sound is not very good, if you do not require high sound quality feel better.
Singing the best speakers, is plugged into the 220V voltage HiFi amplifier supporting KTV speakers. Because the amplifier sound quality is good, singing sound is more HiFi (high fidelity), so KTV speakers than trolley speakers sound quality is good.

Appreciation of music with the best 2.0 HiFi amplifier, should not be equipped with AV amplifier, AV amplifier because more channels, the price cost factor to do more simple --- small output power, poor sound quality. (Many imported AV amplifiers are false labeling of the maximum power, or 2 channels bridged to a mono channel, the output power is a little larger, but that is the power of mono output, not stereo output, not surround sound output power).
