1. Place the rack, cabinet or speaker stand exactly where you want it and mark each spike hole in the carpet. (This can be done by placing Sellotape under the spikes and pressing down so that the spikes puncture the tape.)

2. Insert a screw (use 1" (25mm) No. 8 crosshead Philips or Posidrive countersunk screws) into each hole and screw it down. The screws will disappear into the pile of the carpet and become invisible (we suggest doing this while your partner is out!). Each spike will now sit exactly on a screwhead and the result will be a great improvement in bass definition and clarity.
