- 2 x IKEA FROSTA Stools
- 8 x IKEA dowels
- Some rope
Basically, you'll need 4 FROSTA stool legs and 4 dowels for each speaker stand. Simply stick four of them together, using the dowels to keep the speaker from slipping backwards and to prop the stand up to reduce the aggressive tilt angle.
Glue would probably be a sleeker alternative, but since there are holes already in the front, you can use similar colored rope to tie the pieces together and to cover the pre-drilled holes.
For the curious, those are the AudioEngine A5 speakers in White ($350).
