{"product_id":"stack-audio-auva-70","title":"Stack Audio AUVA 70 喇叭隔離腳","description":"\u003cp\u003eStack Audio AUVA 70 is a speaker isolation foot — not an equipment foot. It replaces stock spikes or pads and screws into the existing threaded inserts under the speaker. Machined from solid aluminium with three tuned particle chambers (including tungsten powder). Vibration is converted to heat by particle collisions. The rigid shell keeps the speaker planted. Designed and made in the UK.\u003c\/p\u003e\u003cp\u003eDiameter 70 mm, height 30 mm (excluding bolt and spike). About 370 g each (without accessories). Load capacity about 275 kg (per manufacturer). Thread options include M6, M8, M10, M12 and more, with adapters and nuts. Hard floors: pre-fitted felt; carpet: 15 mm or 25 mm spikes. Usually sold in sets of 4 or 8 (8 for a pair of speakers).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDesign highlights\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSpeaker isolators — replace stock spikes\u003c\/li\u003e\u003cli\u003eØ70 mm, 3 particle absorption chambers\u003c\/li\u003e\u003cli\u003eLoad capacity about 275 kg\u003c\/li\u003e\u003cli\u003eHard-floor felt or carpet spikes\u003c\/li\u003e\u003cli\u003eMultiple thread adapters\u003c\/li\u003e\u003cli\u003eMade in the UK\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSonic character\u003c\/strong\u003e\u003cbr\u003eTighter less-blurred bass, clearer mid\/highs, surer timing. More spatial detail and stable imaging. Especially clear on suspended wood floors where stock spikes still excite resonance.
