SECTION 4
Operation
4.1
Acoustic Level Warning
Danley Sound Labs subwoofers can produce sound levels capable of causing permanent hearing damage from prolonged
exposure. The higher the sound level, the less exposure needed to cause such damage. Avoid prolonged exposure to the high
sound levels from the subwoofer. Some Tapped Horns are capable of levels in excess of 140 dBSPL! Levels this high can cause
permanent hearing loss! When operating at these high sound pressure levels the user is strongly encourages to use hearing
protection. Danley Sound Labs accepts no liability for hearing damage from using our subwoofers!
4.2
Operator Responsibility
It is the responsibility of the operator to maintain safe operating levels and to insure that the audience is not harmed by excessive
levels. This is a chart of the recommended exposure limits set by OSHA.
4.3
Aqua Tight Coating
Aqua Tight Coating
includes full two layer fiberglass finish for maximum moisture resistance as well as a special polyurea coat
bonded to the fiberglass exterior & two topcoat layers of UV resistant color stabilizer. It also includes all stainless steel exterior
fasteners, an acoustically transparent moisture barrier to the grille, waterproofing the driver cones and sealant for the input plate,
handles or cabinet fixtures. The finish also includes a powder coated stainless steel grille, sealed, waterproof
cable leads (12’
length standard), and fully caulked
all external joints (except for the “weep” opening at the bottom of the grille).
If a repair is to be made on a loudspeaker with “AT” finish, a few steps must be taken to insure the speaker remains water
resistant in future usage. The caulking must be removed to free the grill and driver access panels. Once the repair is finalized,
the bolts must be coated with silicon and the caulk must be replaced on all panels that have been removed.
