Mofi makes a Sourcepoint

MoFi SourcePoint 10 Loudspeakers Walnut Pair

Mofi’s Sourcepoint 10 speakers are the result of 18 months of research and development led by Andrew Jones who has worked with KEF, ELAC and TAD in the past. “Regardless of what an audio product costs, my passion is to deliver a level of sound quality and an experience that is far beyond the asking price,” says Jones.

Sourcepoint 10 is a two-way speaker using an original 10-inch concentric driver, its diameter selected as the ideal size for minimising cone movement while producing deep bass. Having evaluated a variety of exotic materials, Jones opted for paper for the “quintessential combination of properties” for the size of the cone he needed. The team worked from a paper pulp mix and devised a cone shape that both optimises resonant behaviour and meets the requirements of the tweeter waveguide.

The tweeter is a 1.25-inch soft dome with a wide-roll surround and large-diameter voice coil, capable of working down to the low 1.6kHz crossover point. A wide surround extends the low and high-frequency response of the tweeter, while the loading of the waveguide increases the low-end efficiency by a significant margin.

After months of running magnetic field simulations, Jones selected high-flux neodymium magnets for the woofer and tweeter that are precisely coupled to create a compound effect: each aids the other in driving the flux across the woofer and tweeter gaps. The so-called Twin-Drive magnet structure was also built to create a fully symmetrical magnetic field, which “eliminates flux modulation for extremely low intermodulation distortion (IMD) and accurate reproduction”.

Considerable thought was also given to the cabinet and shape of the two-inch-thick front baffle. The sculpted, multi-faceted baffle stands in front of the mid-century-inspired cabinet frame to reduce diffraction. The cabinet has an internal volume of 50 litres, a size chosen to deliver bass extension and efficiency, with a sensitivity of 91dB, low-frequency point of 42Hz, and true eight-Ohm impedance with a minimum of 6.4 Ohms. Sourcepoint 10 is available in real wood veneer of either satin walnut or black ash with a price of  £4,500, the stands are £550.
