On the left side of each group is a Klipsch Synergy B-3, the center spot is occupied by the SVS SBS-01, and the unusual looking speaker on the right is an Optimus PRO-LX5II, which is no longer manufactured.
Of the three speakers, the Klipsch B-3 is the most efficient and produces the most powerful mid-range and bass performance, as well as producing louder volume using less output power, but the SVS SBS-01, although more restrained in the highs and midrange, produces more accurate, tighter bass of the of the three speakers. On the other hand, the Optimus, with its unusual Lineaum Diople Tweeter, produces a lively mid-range, and widely-dispersed highs, but is weaker and less accurate in bass response of the three speakers.
The Klipsch is the more expensive of the three speakers, coming in at a suggested price of $330 a pair, the SBS-01 comes in a $225 a pair, while the PRO-LX5II, if it were still being made, would probably come in at about $149 a pair, but may be found on sources, such as eBay, now for about $50 - $80 a pair.
