{"product_id":"stack-audio-auva-sw-isolator","title":"Stack Audio AUVA SW Subwoofer Isolation Feet","description":"\u003cdiv\u003eStack Audio AUVA SW is a subwoofer isolation foot—not a generic pad. Subs move lots of energy and excursion; ordinary feet either couple vibration into the floor or collapse if too soft. AUVA SW uses a three-layer hybrid: upper AUVA particle chamber turns vibration into heat; mid machined aluminium shell guides deflection and resists crush; lower CSA-SW silicone absorber is tuned for subwoofer bands. Made in the UK.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003eSix weight grades keep the silicone in its sweet compliance range—too hard and isolation fails; too soft and it wobbles. Sit under the cabinet (adapter plate included) or use threaded adapters where the sub has inserts. Height about 40–52 mm—matches many REL stock feet. On carpet, skip spikes for best isolation.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eDesign highlights\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e• Upper: AUVA particle damping → heat\u003c\/div\u003e\n\u003cdiv\u003e• Lower: CSA-SW silicone tuned for subs\u003c\/div\u003e\n\u003cdiv\u003e• Aluminium shell guides deflection under high SPL\u003c\/div\u003e\n\u003cdiv\u003e• Six weight grades, 1–56 kg\u003c\/div\u003e\n\u003cdiv\u003e• Sit-under or threaded install; spikes, felt, adapter plate included\u003c\/div\u003e\n\u003cdiv\u003e• Made in the UK\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eListening character\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003eBass still goes deep, but start\/stop is faster and pitch clearer—less cabinet-plus-floor “hum.” Sub integrates with mains more easily; mids\/highs can clean up as less vibration reaches the rack.
