Ultimatum – XLS

The ULTIMATUM XLS loudspeaker is a standmount 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 four discrete internal cavities each optimised for purpose. The Mid/Bass tuning is optimal for the main enclosure volume while the HF cabinet 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 EMIT supertweeters are similarly isolated.


A dedicated XLS stand is available as an optional extra. It comprises an Italian black-slate baseplate with steel uprights and a tri-laminate top-plate made from steel/bitumen/steel.

M6 spikes are used to couple the stand to the floor, and adhesive putty is supplied to be used as an interface between the speaker and the stand. The rear upright can be filled with lead shot, dry sand, or similar ballast.

The XLS stand has been designed specifically for the XLS loudspeaker. It makes an ideal partner, allowing the XLS to perform optimally in any environment.
