The visible main drive unit handles bass and midrange and is isobarically loaded by similar drive units located inside the cabinet. The main tweeter is mounted above it, within a sculpted sub-baffle designed to minimise unwanted diffraction effects. The treble output is augmented by the two upward-firing EMIT super-tweeters mounted atop the enclosure.
Another ULTIMATUM feature is the use of decoupled baffles. The driver-mounting baffles (front & top) are fixed to the main structure via a polyethylene membrane. The total baffle is a 45mm thick 'sandwich' of birch plywood, polyethylene and MDF. This provides a rigid non-resonant platform, which is ideal for optimal performance of the drive units.
The crossover is a minimalist 3 element type (plus damping & attenuating resistors) employing precisely toleranced, low loss air-cored inductors and Neat's newly-developed polypropylene film & foil capacitors. The speaker exploits predominantly first-order crossover slopes and mechanical roll-offs for a natural, uninhibited performance.
