The Svelte shelf from specialty manufacturer, Symposium Acoustics, is a multi purpose anti-resonant platform that could be used under components or speakers. Weight limit varies between 30 lbs to 300 lbs depending on component and where the load bearing will be. If it is placed flat on the floor, the shelf can take up to 300 lbs (like a speaker or amplifier for example) or if they are placed above four footers at each corner, it can take anything up to 30 lbs. So far, we place them over the existing shelf on our rack and usually under CD players or preamps. We have also tried using two of them (we have two for sale but the listing and price is for one only) under speakers with very good results. The two surfaces are polished stainless steel and sandwiched in between are their proprietary layers of foam that seems to be the epicenter of their “magic”.
Cosmetically, there are scratches and scuff marks on the stainless steel surfaces from components and speakers previously placed on it. On the rear, there is a small puncture in the foam layer but it does not go deep nor does seem to affect its “operation”. The shelf will be securely packed for safe shipping.
