SOUNDTUBE EXCELS IN INGRESS PROTECTION TESTING
20 October 2015
SoundTube Entertainment has achieved IP64 and IP54 ratings for all speakers in the company’s 31 Series of 3” speakers. The series includes surface-mount, pendant, in-wall and in-ceiling models.
IP (Ingress Protection) testing measures a speaker’s ability to withstand particulate and water exposure and is especially important for determining the viability of a product’s usage outdoors. “The IP rating consists of two numbers,” said David Staley, MSE Audio VP of Engineering & Operations. “The first one ranges from 0 to 6 and signifies the level of particle protection (primarily dust); the second number ranges from 0-9 and is for water protection.” Staley noted that test specimens are subjected to two sets of testing. For the particle ingress testing, the units are placed in a sealed chamber and then a heavy concentration of very fine dust is introduced and swirled around to see if it gets into the enclosure. The water ingress testing is similar, but the water is sprayed from a shower head nozzle onto the test specimen from all angles. For both tests, the sample is removed from the chamber after the test period and examined for ingress inside the enclosure.
“We’re happy to report that the RS31-EZ, our pendant model, and the SM31-EZ, the surface-mount model, both passed testing at an IP64 level. This means there was no dust ingress in the speaker enclosure and these both can withstand water spray and splashes from all directions at low pressure levels,” Staley said. “Our in-ceiling CM31-EZ and in-wall IW31-EZ both passed the IP54 tests meaning there was limited dust ingress, but not enough to affect the speaker’s performance — and they had the same level of water protection as the RS and SM31 models.”
