Very big famous Bose Studiocraft speakers. Woofers are as new, no foam problems. Sound fresh an crisp. Pictures are part of the description. Just minor signs of use. 1 box has a few spots on the front and top. Following serial numbers! These are the largest speakers of the Studiocraft ST-line. A true icon of the eighties. The sound is full, tight, and clear, which, in my personal opinion, is one of the best-sounding speakers ever made by Bose. They are quite rare, and other models like the 200st and 300st, which are still widely offered online, are kept by collectors for themselves, such as the 500ST's (or ML5's). These speakers are still in very good condition. Recommended power: from 20 to 120 watts. Impedance 4-8 ohms Weight: 8 kg Height: 61 cm width: 34 cm Depth: 21 cm To deliver this product properly, it is packaged in very strong boxes, additionally wrapped in bubble wrap. In addition to the sturdy packaging, the box is marked as fragile with 'fragile' tape. Carefully insured shipped!
