Rugged, versatile speaker stands Pangea's all-steel LS300 speaker stands are designed to work with a wide variety of bookshelf speakers. They range in height from 20" to 36", so you can place your speakers at the best height for your listening environment. We recommend positioning your speakers' tweeters at approximately the same height as your ears when you're seated in your favorite listening spot. Spikes are included for extra stability on carpet, and soft top pads help isolate the speaker from unwanted vibrations. Two hollow columns can be filled with sand or shot for ballast, and the third features holes near the top and bottom for neatly routing speaker wire.
