There are also two centre speakers and a tri-mode surround speaker in the range, which will hit UK shops late next month.
The company says "the Synchrony designs are exhaustively engineered, balanced, and voiced to produce a consistent, accurate, transparent and dynamic musical reproduction across the line."
The smallest speaker in the Synchrony range is the £999/pr Two B, with the £1499/pr One B being slightly larger, and using a bigger mid/bass driver to give it useful output down to 40Hz.
The two floorstanding speakers are the Synchrony One, at £2999/pr, and Synchrony Two, at £1999/pr. The larger speaker uses three identical 16.5cm woofers, each rolling off at a different frequency to give a smooth on-axis and off-axis response.
Each driver is also housed in its own enclosure, each of these being of a different size and having its own port tuning.
The smaller Synchrony Two uses the same design, but with 13.5cm drivers.
Centre-channel duties can be handled by the £1199 Synchrony One C or the more compact Synchrony Two C, at £899, while the surrounds are the tri-mode Synchrony S, at £1299/pr.
These offer the choice of bipole, dipole or monopole operation, and like the other Synchrony speakers are available in hand-rubbed dark cherry or black ash veneers.
PSB speakers are distributed in the UK by Armour Home Electronics.
