The Borresen 05 – 2.5 Way Loudspeaker is designed to be used in a high-end audio system, paired with a high-quality amplifier and other components. It is a large and heavy speaker, standing nearly four feet tall and weighing over 100 pounds, so it is best suited for larger listening rooms or home theaters.

The speaker has a frequency response range of 25 Hz to 50 kHz, which is well beyond the range of human hearing. It has a sensitivity of 89 dB, which means it can produce a high volume of sound with relatively little power input.
