The ULTIMATUM XL6 loudspeaker is a floorstanding 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.

 --------------------------------------------------------------------------------

Technical description The enclosure comprises five discrete internal cavities each optimised for purpose. The Bass and Mid/Bass volumes are large to suit the tuning 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.
