SP High Power Loudspeaker Connectors

Amphenol Audio SP High Power Loudspeaker Connectors are chassis mount or in-line connectors with high power (30A) contacts to ensure optimal current carrying capacity for demanding powered loudspeaker applications. Amphenol Audio designed the SP Series to provide distortion-free signals, industry standard PCB footprint, superior wire termination pull out resistance, superior low light terminal ID, and is fully intermatable with existing industry standard loudspeaker connections. Amphenol Audio SP Series High Power Loudspeaker Connectors feature an "easy on the thumb" quick release, vibration resistant latch lock.
