BOSE 501
\ Price Unknown (1 Available in 1976)
Commentary
A speaker system that inherits the design philosophy of 901.
A 25 cm cone unit is used for the low range, and two 7.5 cm cone units are installed for the high range.
The low-frequency unit is installed facing the front, and the two high-frequency units are set in opposite directions with respect to a 45 ° diagonal line. With this asymmetric layout, the radiation pattern of the sound pressure energy spreads in the listening room in a well-balanced manner, so that the sound image does not deviate regardless of the position of the listener.
One of the two tweeters facing the side wall is equipped with a deflector that adjusts the radiation angle of sound.
In most cases, you can get the correct spread by normal position, but if you want more spread, such as a large orchestra, you can get more spread by setting it to the outside.
The network is a dual-frequency crossover network.
