The MB4 speaker can be used with the Bose PANARAY system digital controller to provide smooth accurate spectral response over the entire operating range of the system. The Bose MB4 speaker can also be used with the Bose 1600 or 1800 amplifiers in combination with the MB4 plug-in EQ card to provide active equalization for the system.
The transducer complement shall consist of four low-frequency drivers of 5.2" (13.3 cm) diameter, mounted symmetrically in vertical pairs. Each driver shall have rated impedance of 8Ω and shall be wired in series/ parallel, resulting in composite nominal impedance of 8Ω.
The loudspeaker system sensitivity shall be 87dB-SPL in the 40Hz to 300Hz frequency range with measurements referenced to 1W (2.85V) pink noise input at 1m. The dispersion shall be omnidirectional at all frequencies below 200Hz. The power handling capacity of the loudspeaker shall be 200W continuous pink noise, band-limited from 40Hz to 300Hz.
