Speaker Placement
Many loudspeakers are designed without regard to baffl e step loss. If a woofer has a midband sensitivity of 88 dB for
example, and is mounted on a large infi nite baffl e (like your living room wall), it will maintain the 88 db sensitivity right
down to it’s rated F3. All frequencies, even the large low frequency wavelengths are supported by the large wall.
But speakers are usually mounted in boxes with varying degrees of baffl e width. At a given frequency determined by
the baffl e dimensions, the lower frequency wavelengths start to ‘wrap’ behind the baffl e. This is called a 2 pi to 4 pi
transition and will result in a 6 dB loss in an anechoic chamber.
A typical two way speaker in a normal listening room will exhibit a 3 to 4 dB loss in the bass region. If left unchecked,
most speakers will sound too thin with too much midrange output.
The BR-1 was designed with 4 dB of baffl e step compensation which results in surprising bass output for a 6-1/2"
diameter woofer. The midband is rolled off to match the woofer’s natural in-room response to achieve the excellent
bass performance. The trade off is a loss of some midband sensitivity, with an overall sensitivity of about 83 dB.
In most rooms, you will fi nd the BR-1 to sound best placed approximately 3 feet from the rear wall and mounted on ap-
propriate speaker stands. Ideally you want to place the speakers so they are at least 3-4 ft from side walls if possible.
