With the 802 and 402 Series IV introductions, were any changes made to the 502A model?
No. There were no acoustic or mechanical changes made to the 502A. However, the recommended EQ for the 502A was updated to provide mid/high tonal balance more consistent with that of the 802 and 402 Series IV EQ response.
Does the Panaray 502A require active equalization?
Yes. The Panaray 502A loudspeaker requires active equalization which can be implemented using Bose Professional PowerMatch® amplifiers, Engineered Sound Processors, or SP-24 processors. Additional, generic parametric EQ values are available to use with non-Bose amplifiers and DSP.
Why did you update the recommended EQ for the 502A loudspeaker if the acoustic design did not change?
The recommended EQ for the 502A was updated to provide mid/high tonal balance more consistent with that of the revised 802 and 402 Series IV EQ responses.
What are the primary differences between the Panaray 402 Series IV and the Panaray 502A model?
The 402 Series IV loudspeaker utilizes 4x 4.5-inch full-range drivers to provide 60 degrees of vertical coverage while the 502A loudspeaker utilizes 5x 4.5-inch full-range drivers to provide 70 degrees of vertical coverage. The slim enclosure design of the 502A has low-frequency response down to 103 Hz while the larger enclosure volume of the 402 Series IV provides 73 Hz low-frequency response. In general, the 502A requires additional subwoofer enclosures for full-range music material. Additionally, the 402 Series IV is outdoor rated, while the 502A is rated for indoor-only installations.
What are the advantages of using full-range drivers compared to conventional 2-way, woofer/tweeter systems?
Bose full-range drivers eliminate the need for crossovers and tweeters for unsurpassed reliability in harsh environments and natural vocal clarity. Bose full-range drivers are among the most reliable transducers in the industry, with 99.9% still operating 5 years after the original installation.
What are the advantages of the Articulated Array™ design?
Using full-range drivers allows Bose Panaray loudspeakers to utilize unique driver array placement which provides wide, consistent horizontal coverage, with vertical coverage patterns that differ by model to meet the needs of different applications. The wide horizontal and controlled vertical coverage of the Panaray 502A loudspeaker – 120° horizontal and 70° vertical – can effectively cover moderate size rooms with a single loudspeaker, for cost-effective speech reinforcement with exceptionally natural vocal clarity.
