Neat Acoustics Ultimatum XL10 (ÇİFT)

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.

 Ultimatum range features several key design principles which Neat believe to be of particular importance.

1. Iso-baric (compound) bass loading with bass-reflex tuning.

2. Birch Plywood cabinet construction. Plywood arguably possesses the best sonic behaviour of all wood based enclosure materials.

3. Discrete internal cavities for each drive unit in the system, each sealed from the others. This eliminates interference between the drive units operating within the enclosure, allowing each to do its job unhindered.

4. The use of the 6.5” (168 mm) bass/midrange drive units. This type of main driver offers an ideal balance of the compromises required to deliver speed, depth and crossover cohesion.

5. The use of area-drive super-tweeters for the extension the upper frequencies. Those used in the Ultimatum series extend beyond 40K. It is astonishing how much this information affects the content within the ‘normal’ frequency range.

6. Optimal coupling of the drive unit baffle to the main enclosure. The system used in the Ultimatum is a high density fibreboard baffle, coupled to the main Birch Plywood enclosure by means of a polyethylene membrane. This makes a very inert platform for the drive unit/baffle/cabinet interface, thus allowing all of the drive units to deliver their performance with a minimum cabinet colourations.

The Ultimatum range is far from being the most expensive available, yet offers state-of-the-art performance and is internationally acclaimed as being amongst the very best there is, regardless of price.
