7. Sensitivity rating
The sensitivity rating of the Definitive Technology BP 10 speakers is a crucial specification that defines the speaker’s efficiency in converting electrical power into acoustic output. It’s typically expressed as decibels (dB) of sound pressure level (SPL) at a distance of one meter when driven by one watt of power. This rating directly impacts the amplifier power required to achieve a desired listening volume. A higher sensitivity rating indicates that the speaker will produce a louder sound for a given amount of power, requiring less amplifier power to reach the same volume level as a speaker with a lower sensitivity rating. For instance, a speaker with a sensitivity rating of 90dB will produce a significantly louder sound than a speaker with an 85dB rating, given the same amplifier output. The BP 10’s sensitivity rating is, therefore, a determining factor in selecting a suitable amplifier for optimal performance.
The sensitivity rating also influences the speaker’s suitability for different listening environments. In larger rooms, speakers with higher sensitivity ratings are generally preferred, as they can fill the space with sound more effectively without demanding excessive power from the amplifier. Conversely, in smaller rooms, speakers with lower sensitivity ratings may be more appropriate to avoid overpowering the space. The BP 10’s design, with its bipolar radiation pattern, contributes to its perceived loudness and soundstage width, and its sensitivity rating must be considered in conjunction with these factors when assessing its suitability for a particular room size and acoustic characteristics.
