A must to get the best sound out of your Bose speakers. These stands will keep the speaker from projecting sound onto the surface they are setting on and having it redirected to who knows where. They look awesome and fit many different Bose speaker models. The Instructions on assembly are somewhat confusing until you decipher which speaker they are intending your assembly for. The Bose 321 system kinda fits when you try ti hide the wires in the stand. Requires some disassembly before reassembling. It got a bit confusing. They are very sturdy and do not add much to the footprint of the speaker without the stand. A bit pricey at [...] bucks apiece, but worth the investment in terms of sound quality and aesthetics. Hard to find used since people that have them want to keep them.
