I used this pair of speakers for 7 years and I had no problem. Quality of his copy, remarkable power. I have sold last year to buy yorkville which for me are a little better. I think I will have to keep his weight if not as n'tait lev. 49 kg the pice. Alone is impossible to transport without breaking your back. Otherwise, ts made music, they need at least a subwoofer to the sound is at the top. Input and output XLR and jack, very practical to have both. Adjustable volume.
Wooden box; shame because as and transport they are more like very much. They get damaged quickly.
Trs good quality sound. Montarbo trs is a good brand and w20a can delight of playing in the big leagues.
