I have for sale one pair of equal size Hi-Fi Racks Ltd Podium Isolation Plinths - 445mm x 290mm x 40mm in Oak, with Hi-Fi-Racks own black adjustable cone spikes with locking nuts. In very good condition, I noticed the photos suggest some surfaces are marked / discoloured, this is not the case. They are solid and well made to these dimensions by Hi-Fi Racks, each one weighing 4.2Kg. There are cheaper wooden platforms on the market. As can be seen on the photos, each plinth has 4 smooth holes of 5mm previously used to secure the speakers I used with them. Checked on Hi-Fi Racks website, this size and adjustable spikes last time I checked the pair could be purchased for £550.62. This did not include postage. From a smoke free home. They can be collected from a village just west of Hull and so I would refund full postage costs. Due to high weight if not in UK mainland please check with me for postage costs. Now sending via Royal Mail 48.
