Review: Buen sonido. Buena calidad a bajo precio - El articulo llegó en tiempo indicado. Set de medios lo instalé en un Suzuki Swift, mejoró notablemente la calidad del sonido, reproduce bien las frecuencias bajas y los twiters, aun no los amplifico pero creo q sonarán genial. Compare otro par ahora para la parte trasera del auto.
Review: Not bad for the price - If you want decent sound, this is it. Don’t expect Bose sound (which honestly is trash to a true audiophile) but anything is better than blown. Picked up two pair for my Saab wagon running off the head unit. Sounds good, crystal clear for 60 watts each. With an amp, they are much louder. Don’t expect lows, and don’t use the baffle behind them (waste of money). I’m happy with them, but again these aren’t high end speakers. They are loud, they are clear, and they are MB quart. Huge difference on a 4 channel amp with about 100 watts each.
