Product Overview

30W Installation Speaker

The all new InterM WS Series speaker range are perfectly suited to Cafes, Restaurants, Houses of Worship, Conference and Meeting Rooms and Outdoor Applications where the physical design of the speaker really matters! 

Unlike the previous versions that were mainly used as a monitor or an auxiliary speaker, the new WS series is acoustically optimised to play high quality BGM with extreme accuracy in the vocal range. Plus, it has a useful line-up of powerful output levels from 15W to 80W. Speaker sizes range from a  2.5" super small-sized speaker, to the more common 6.5" speaker in the WS-80T.

The aesthetic design of the WS Series is the result of a lot of analysis of many design ideas and constant feedback received from distributors and Audio Integrators from all around the world. Not only are these speakers beautifully and architecturally designed, but the sizes of the WS series and their 2-way construction perfectly suits the high power output and versatility of the speakers. The WS Series possesses superior specifications in comparison to other companies’ products – especially with sound pressure levels, frequency response and damp-proofing. The WS series also adopts the use of a Knuckle Bracket to adjust angles conveniently and multiple tappings in 70V/100V and 8Ω, which can be used in any country around the world.

Now, you can experience Inter-M’s modern and new WS Series with both your eyes and your ears!
