The 3030FSi speaker stand is designed and sonically optimized for the 3030i bookshelf loudspeakers. Precision laser-cut steel construction and acoustically damped columns ensure quality and performance to complement the loudspeakers. The base is fitted with adjustable, locking carpet spikes with optional rubber caps for an equally solid stance on wooden or tiled floors to ensure you get the very best sound performance from your speakers. These stands are not compatible with the 3000 Series or 3010i - 3020i Speakers.
