This 2-way monitor is based on a the Dayton Audio 1-1/8" silk dome tweeter and a 6-1/2" woofer. It was designed to provide a low cost, easy to build 2-way system for the speaker building novice. The end result is a kit that can be built in a couple of hours and has a sound that will rival mass market speakers costing two or three times its price. The sound of the BR-1 is smooth and detailed, with a convincing soundstage. The tonal balance is on the warm side of neutral. Most other small mass-market speakers lack bass extension and substitute a boomy peak in the 60-80hz range to compensate for this shortcoming. The BR-1's bass extends into the mid 40's and is slightly ovedamped (tight) due to an extended bass shelf ported alignment, which is unusual for a system of this size.
