F10 Select Driver

Differences between the F10 Neo and F10 Select drivers

The F10 Select driver has a ferrite-based magnetic motor and maintains the same magnetic field gap of 9 mm with an underhung design. The X-max value of both drivers is the same; thus, the cone control by the magnetic motor for F10 Select is very good. However, due to the lower magnetic field (1.7 Tesla) of F10 Select, the sound contour and microdetails, while still extraordinarily good and way above those of the majority of audiophile speakers, are not at the same groundbreaking level as in the Nenuphars.

We also knew that we wanted to end up with smaller loudspeakers than the Nenuphar, so to keep the sound balance that we all like, the efficiency of the drivers had to be brought down a bit. We decided to aim for a sensitivity of 90 dB since it is the value that would work out beautifully with over 99% amplifiers on the market. The drivers have an impedance of 8 Ohm and are very easy to drive. Basically, any 8W SE 300B amplifier would be able to rock the house.

Also, F10 Select is our first driver using a rubber surround. It is heavier than the equivalent one made of foam. However, since we needed to add more mass to the driver to obtain excellent balance in a smaller cabinet, it was a perfect opportunity to increase the longevity of the drivers at the same time. The rubber surround of the driver should last for at least 30 years, as compared to about 15 years for the foam ones. The cabinets of the Jazzon loudspeakers using F10 Select drivers are smaller than those of the Nenuphars. They are 10 cm smaller in depth and 5 cm smaller in height, resulting in 30 x 40 x 100 cm cuboid-shaped cabinets.
