The LS-20 speaker stands has been custom designed to match the our Reference Line of speakers. The 6” x 8.5” steel top plate ensures a good fit with either of these series. The included rubber bumpers further help dampen cabinet vibrations. The stand itself is constructed from an aluminum center column with a steel top plate and a substantial “H” shape steel base plate. The mass of the base plate adds extra stability to the stand. The stand comes equipped with both spikes and adjustable rubber feet allowing use on either carpet or solid floors.
