ULTIMATUM XLS Loudspeaker
The Ultimatum XLS is a stand mounting loudspeaker of compact proportions, delivering the bass
weight, scale and dynamics of a significantly sized floorstander. The mid/bass drivers in the XLS are
mounted isobarically which when aligned correctly, as in the XLS, gives deep clean bass delivery.
Combining this authority with the superb sounding Sonomex domed XL high-frequency unit is the art
of the Ultimatum.
The XLS cabinet is constructed from slow-
growing birch plywood, chosen as it is
consistent and has the best resonance
behaviour. The front baffle is from precision
routed controlled density fibreboard
coupled to the front of the cabinet by
means of a polyethylene membrane. This
makes an extremely inert platform for the
mid/bass and high frequency drivers.
The main Mid/Bass driver is a special
version of the Neat 168mm driver with an
aluminium phase plug to aid dispersion and
reduce dynamic compression.
Despite its modest proportions, the XLS
delivers a complete full-range performance
which eclipses many much larger designs.

“The Ultimatum is a labour of love and the end result
of painstaking development and refinement. Such
quality doesn't come cheap, but Neat's Ultimatum
deserves recognition as amongst the very best there
is, irrespective of price.”

ULTIMATUM XLi Loudspeaker
The ULTIMATUM XLi is a big-sounding design housed in
an elegant room friendly enclosure.
The ULTIMATUM XLi loudspeaker is floorstanding design which adheres to all the principles that have
marked out the ULTIMATUM project and given it such enduring success. The ultra-rigid birch-
plywood enclosure, innovative baffle-decoupling technology, 'isobaric' bass loading and use of twin
EMIT ribbon-type super-tweeters are employed here to deliver the ULTIMATUM promise of a lifetime
of musical enjoyment.
The enclosure comprises six discrete internal cavities each optimised for purpose. The mid/bass
volume is optimised to suit the tuning of the iso-baric loaded main drive units while the HF cavity is
small to increase rigidity and to stop back pressure from the Mid Bass driver adversely affecting the
rear chamber of the tweeter. The two supertweeters are similarly isolated.
ULTIMATUM XLi
The main structure is damped 18mm Birch Plywood, whilst the drive unit baffles are constructed
from a 45mm thick 'sandwich' of Birch Plywood, Polyethylene and MDF. This provides a rigid non-
resonant platform, which is ideal for optimal performance of the drive units.
The mid/bass driver is a special version of the Neat 168mm driver with an aluminium phase plug to
aid dispersion and reduce dynamic compression. Its enclosure is loaded by a low Q reflex tuning.
A separate sub-cavity contains two EMIT type super-tweeter drive units.
The HF Unit is a modified SEAS XL SONOMEX domed XL unit with additional damping and support.
The crossover is a minimalist 4 element type (plus damping & attenuating resistors) employing
precise-tolerance, low-loss air-cored inductors and newly-developed polypropylene film & foil
capacitors. The speaker exploits predominantly first-order crossover slopes and mechanical roll-offs
for a natural, uninhibited performance. The crossover network is housed in its own separate cavity,
thus isolating it from the magnetic fields created by the drive units.
