Description
The 10W500 is a low frequency driver designed to satisfy the need for a 10" ferrite loudspeaker
combining excellent linearity with good sensitivity and power handling characteristics. The
transducer is the evolution of the 10W400, and is primarily recommended for compact bass
reflex systems in enclosures as small as 25 lt. The paper curvilinear cone is carried by a
dampened linen, triple roll front suspension to control vibration modes that ensures good travel
control and linear excursion. The 50 mm diameter copper wire voice coil employs the
Interleaved Sandwich Voice coil (ISV) technology, where a high strength fiberglas former carries
windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an
extremely linear motor assembly which, in conjunction with the highly advanced design of the
magnetic structure, provides a high force factor or BL. Another feature of 10W500 is the fine air
channels between the chassis back plate and the top plate of the magnet, which draw heated air
out from the voice coil gap and dissipate the energy through the chassis casting. The top and
back plates of the magnet assembly have been designed to optimise flux density and BL factor
in the air gap using our in-house FEA CAD facility.

Notes
1) AES power is determined according to AES2-1984 (r2003) standard.
2) Program power rating is measured in 30 lit enclosure tuned 55Hz using a 70 - 2000Hz band
limited pink noise test signal with 50% duty cycle, applied for 2 hours.
3) The peak power rating represents the maximum permitted instantaneous peak power level
over a maximum period of 10ms which will be withstood by the loudspeaker without damage.
4) Sensitivity represents the averaged value of acoustic output as measured on the forward
central axis of cone, at distance 1m from the baffle panel, when connected to 2,83V sine wave
test signal swept between 500Hz and 2500Hz with the test specimen mounted in the same
enclosure as given for (1) above.
5) Frequency range is given as the band of frequencies delineated by the lower and upper limits
where the output level drops by 10 dB below the rated sensitivity in half space environment.
6) Power compression represents the loss of sensitivity for the specified power, measured from
50-500 Hz, after a 5 min pink noise preconditioning test at the specified power.
7) Linear Math. Xmax is calculated as (Hvc-Hg)/2 + Hg/4 where Hvc is the coil depth and Hg is the
gap depth.
