The ULTIMATUM XLS loudspeaker is a standmount design that 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 optimized for the 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 super tweeters are similarly isolated.
