Abstract

　聴取中心軸に対して対称に設置され、内側方向に音を放射する第１スピーカユニット１２、１５と、前または外側方向に音を放射する第２スピーカユニット１３、１６を備え、センターチャンネル信号を第１及び第２スピーカユニット用の信号として各々処理する第１及び第２処理部を備え、フロントチャンネル信号は第２処理部の出力信号に重畳する。第１処理部は、ＨＰＦ３３と、高域成分を増大する第１ハイシェルフブロック３４を備え、第２処理部は、ＬＰＦ３８と、低域及び高域成分を各々減衰させるローシェルフブロック３６及び第２ハイシェルフブロック３７を備える。聴取位置の近い方の第１及び第２スピーカユニットから到達するセンターチャンネル再生音が、位相差により中音域において弱め合う。中央音像定位が得られる聴取範囲を拡大し、センタースピーカをフロントスピーカシステムと一体構成可能である。
