Def Tech Has Bipolar Non-Disorder

Definitive Technology has long been a leader in bipolar loudspeakers (with drivers on both sides) so the BP8000 ST Series carries on a long tradition with four towers, including active side-mount subs, at prices from $599-1499/each. Just as novel are the XTR on-walls (pictured) with their extruded aluminum enclosures and both active and passive drivers. They go for $499-899/each.
