Test Bench: The 15DS100 15” Pro Sound Subwoofer from B&C Speakers

This Test Bench explication characterizes the 15DS100 15” professional subwoofer from B&C Speakers. This new transducer from the Italian company is a very high power handling design, able to deliver 3kW continuous (1.6W nominal), thanks to B&C's latest generation of very long voice coils - a great asset in applications from discreet PA subwoofers to three-way PA speakers. The B&C 15DS100-4 uses a proprietary 12-spoke cast aluminum frame with cooling vents for the neodymium FEA motor, which uses a 4” four-layer voice coil wound with round aluminum wire on a non-conducting glass fiber former.

Bonding is an important point when it comes to ensuring the quality of each finished loudspeaker. What you need: Most precise adhesive dispensing and absolute repeatability in fast processes! preeflow dispensers are proven in loudspeaker dispensing applications worldwide: Bonding of coils, magnet system, membrane damper adhesives, wire fixation and contact protection. Smallest adhesive quantities starting from 0.001 ml can be applied – with a repeatability higher than 99%

A sound source, such as a loudspeaker, will experience an increase in directivity with increasing frequency, as the wavelength of sound becomes small compared to the baffle’s size. Since the baffle the driver is mounted on is larger than the driver, this occurs at a lower frequency than for the driver diaphragm itself.

Within the audio chain, the loudspeaker could be the element that most influences a user’s auditory experience. A loudspeaker is not only the final element that converts electric input into an audible output, but it is also responsible for an increasing portion of the system’s cost, inefficiency, weight, and size, making it a crucial element for the costumer and the manufacturer. This article, published in Voice Coil, May 2016, discusses ways to use digital signal processing to improve loudspeaker performance.
