Transducer manufacturer Lavoce Italiana has announced the CSF153.00K 15-inch ferrite common HF/LF magnet coaxial loudspeaker driver.
CSF153.00K offers 700W programme power handling and 98dB sensitivity for the LF, and 120W programme power handling and 108dB sensitivity for the HF. The LF woofer uses a 3-inch edgewound copper voice coil on a glass fibre former and the Polyimide diaphragm and surround employed for the HF uses a 1.75-inch edgewound copper-clad aluminium voice coil on a Kapton former. This combination offers a frequency range of 50Hz-20kHz with low harmonic and intermodulation distortion due to the addition of double demodulating rings.
As will all the five models in the current CSF range (6.5-inch, 8-inch, 10-inch, 12-inch and now 15-inch) each design uses component parts from Lavoce’s range of compression drivers, and feature a single ferrite magnet, low distortion ‘dual-gap’ motor. This motor is designed using an advanced linear modelling technique which enables the review of a finite element electromagnetic model (2D-axi) of the dual gap motor to optimise symmetry in Bl(x), to linearise Le(x) and to minimise parasitic effects and reluctance force on the LF voice coil. This common HF/LF magnet coaxial development brings the LF and HF voice coils in closer unification than traditional coaxial designs to better combine their acoustic centres for improved coherency, dispersion, and alignment optimisation, creating high-performance and cost-attractive solutions for compact portable or install systems to high-performance stage monitors and larger install systems.
‘The market for common HF/LF magnet coaxials is still strong for us as our OEM partners find innovative ways to maximise this technology in compact audio solutions,’ says International Sales Director, Kevin Shove. ‘By using our advanced development tools and resources on these unassuming steel basket and ferrite magnet coaxial designs, we have been able to offer a premium performance line-up with very interesting price points, which is always a welcome combination for our customers.’
