• Excerpt from brochure: Sony SS-E 21 , SS-E 44, SS -E 51 MK II, SS-E 71

• The SS-E71 is a typical mid-range box of that time: 3-way, closed, compact, large woofer, minimalist crossover with widths according to the chassis data sheets

• Due to the too small net volume of the woofer housing, the Qtc is > 1 and consequently the suboptimal pulse behavior in the low-frequency range with a rich frequency response increase in the upper bass. Nevertheless, not all contouring in the bass range is lost, which speaks for the quality of the woofer. The midrange is quite clear and present.
• The treble range is sometimes pointed and harsh and not very detailed.
• Overall, despite its weaknesses at room volume, the SS-E71 is more broadband and "open" looking than some modern speakers with their over-damped metal diaphragms. However, due to the much too small woofer housing and the 6dB filter, it is not very level-resistant and low-distortion (IM) and the tweeter does not appear to be qualitatively equivalent to the cone chassis used.
• A box is designed for room volume with built-in loudness. However, this is acceptable. But I would not want to put down more than 100 € per couple needed. "Vintage" is not an argument for this.
