Ultimatum XL10

Floorstanding Speaker

The ULTIMATUM series of high-performance loudspeakers was conceived by Neat founder, Bob Surgeoner, in 1993 and launched in 1999 with the introduction of the Ultimatum MF9.

The XL10 is the result of a complete revision of the 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 unitbaffle 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.
