Review: Seems to work - Solid construction. Still evaluating performance.
Review: Muito bom, serviu para utilizar meu subwoofer em dois equipamentos distintos, evidentemente, não ao mesmo tempo e sem risco de algum tipo de curto. Justamente o motivo da compra. Fiz o mesmo com as caixas acústicas, só que com outro produto adequado para elas. Assim, utilizo um mesmo conjunto de caixas e subwoofer em dois equipamentos distintos: um HomeTheater Onkyo para filmes e, em um Amplificador estéreo Denon para ouvir musicas.
