Made with the same materials and loving care in our Peterborough, Ontario factory as every other product we make, the 2.5B³ will still surprise you with it's startling dynamics, crystal clarity and 3D enveloping spaciousness. You've really got to hear one to appreciate what an incredible deal this model is.
