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.
Pictured here is the XL10 (why do I always want to say ‘fireball’?).
The range comprises the XLS stand-mount, Xli, XL6 and XL10 floor-standers.
In the case of the XL10, 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.
