Pioneer S-ESR2TB home theatre speaker set, black

Bass built in.

This slim tall speaker package smartly integrates woofers on the side, enriching its sound with powerful bass without the need for an additional subwoofer.

The 3-way tall speakers each have a large 16 cm woofer with a special concaved, stiff cone for rumbling lows.

The woofer effect is amplified by a “twin” passive radiator cone. This extra 16 cm cone booms along with the woofer to provide20% more bass. Additionally, it decreases distortion.
