Footnotes:

  • Frequency response and range measured on-axis with recommended active EQ in an anechoic environment.
  • Power handling tested using pink noise filtered to meet IEC 268-5, 6 dB crest factor, 100 hours, with recommended EQ.
  • Sensitivity measured in free field (no boundary-loading gain) with recommended active EQ, referenced to 1W/1m.
  • Maximum SPL calculated from sensitivity and power handling specifications, exclusive of power compression.

 

Architects' & Engineers' Specifications 

The loudspeaker shall be a multiple driver, low-frequency system with matched active equalization as follows:

The transducer complement shall consist of four low-frequency drivers of 5.25" (133 mm) diameter, mounted symmetrically in vertical pairs. Each driver shall have rated impedance of 8 ohms and shall be wired in series/ parallel, resulting in composite nominal impedance of 8 ohms.

The system sensitivity shall be 87 dB SPL in the 45 Hz to 310 Hz frequency range with measurements referenced to 1 watt (2.85 V) pink noise input at 1 meter. The dispersion shall be omnidirectional at all frequencies below 200 Hz. The power handling capacity of the loudspeaker shall be 200 watts continuous pink noise, band-limited from 45 Hz to 310 Hz.

The loudspeaker shall be a vented enclosure, tuned at 45 Hz. The input connectors of the Panaray MB4 speaker shall consist of two (2) parallel Speakon® NL4 receptacles.

The enclosure of the MB4 loudspeaker shall be composed of high-density wood composite with high-impact polypropylene end caps. Its outer dimensions shall be 26.7" x 10.2" x 18.2" (678 mm x 260 mm x 463 mm). Its weight shall be 45 lb (20 kg).

The loudspeaker shall be the Panaray® MB4 modular bass loudspeaker.
