JBL Studio 590 Floorstanding Loudspeakers (Pair)

JBL Studio 590 座地式喇叭 採2.5音路3單體低音反射式設計的Studio 590，搭載一只全新開發的1吋Teonex振膜高音，擁有高達40kHz的高頻表現，中低音的部份交由二只8吋PloyPlas振膜低音單體，搭配SFG（Symmetrical Field Geometry）磁力引擎，這些是繼承自JBL錄音室監聽喇叭的單體技術，擁有35Hz的低頻延伸能力。 箱體部分，原廠使用厚度為19mm的MDF板材來打造箱體，而且還特意設計成非平行面結構，這是高階喇叭常見的設計手法，目的是要避免平行面箱體在內部產生駐波干擾音質的問題。 Dual 200mm (8") Floorstanding Loudspeaker with High-Frequency Compression Driver in a Horn and Classic JBL® Bass The JBL® Studio 590 floorstanding loudspeaker brings professional-quality sound to the home experience. The Studio 590 uses the technology that JBL engineers developed for pro-audio loudspeakers to deliver accurate, powerful sound to your living room. The Studio 590 floorstanding speaker is a perfect complement to other members of the Studio 5 Series, including the Studio 530 bookshelf and the Studio 520C centre-channel loudspeakers.
