Most Expensive Speakers
Transmission Audio Ultimate System

Price: $2 million per pair

With a total of 12 units—four dipole subwoofers, two dipole mid-woofers, four dipole medium-frequency and high-frequency ribbon panels, and two dipole high-fidelity super ribbon panels—Transmission Audio’s Ultimate speaker system is a hefty piece of equipment, spanning 37 feet and weighing 5 metric tons. All units are made from aircraft aluminum and have stands in polished red or black granite. The set was introduced in late 2009, and so far two pairs have been preordered, says Bo Bengtsson, president of Transmission Audio. None has yet been delivered, as the assembly time is about six months.
