Why it mattered

  1. 01

    Demonstrated that intelligible amplified music and speech could be delivered across an unprecedented outdoor audience.

  2. 02

    Made festival sound a visible engineering discipline rather than an enlarged club PA.

Engineering record

System design
Hanley Sound built custom horn-loaded loudspeaker towers and delay coverage for the Bethel site rather than relying on a standard commercial package.[1]
Microphones
Shure documents the Model 565 Unisphere as the principal vocal microphone used on the Woodstock stage.[2]

Original pricing

No reliable build cost located

2026 equivalent

Not calculated without a reliable original price.

Published claims about the system's expense lack a sufficiently clear primary cost record.

Use in the field

Bill Hanley brought experience from the Newport Folk Festival and Fillmore East to the August 1969 Woodstock production.[3]

Professional reactions

Later recollection · January 1989 (reprinted 16 August 2019)

Hanley recalled choosing Altec 290 high-frequency drivers after failures with JBL drivers and expensive diaphragm replacements. His excitement about a larger concert system was tempered by practical survival: he needed drivers that would stay together on the job.
