Neat Ultimatum XL10
The Neat Ultimatum XL10 is a big high-end audiophile floorstanding speaker offering amazing performance and dynamics.
The Ultimatum project was a labour of love for Bob Surgeoner. It began in 1995 as a no-compromise design intended to deliver the very best attributes of Neat’s accumulated ideas and expertise, and development took place over several years.
The XL10 is the result of a complete revision of the original MF9, building upon its considerable strengths in order to deliver a world-class full range performance for the 21st century.
The enclosure comprises eight discrete internal cavities, each optimised for purpose and each different. The bass/midrange volumes are larger to suit the tuning whilst the main HF cavity is small to increase rigidity and resist back pressure from the main drive units. The two EMIT super tweeters are similarly isolated.
The main structure is damped 18mm Birch Plywood sourced from slow-growing forests as this ensures the densest, most consistent material.
The drive unit baffle sections are constructed from a 45mm thick ‘sandwich’ of Birch Plywood, Polyethylene and MDF. This provides a rigid non-resonant platform which allows the drive units to operate with minimal colouration.
All of these features are woven together in the traditional Neat fashion: hundreds of hours of listening tests, empirical experimentation and years of expertise guarantee that the end result is a classic loudspeaker with qualities that few can equal.
