The crossover connection
Kudos’ obsession with seamlessly matched drive units is driven by designer Derek Gilligan’s firm belief that one of the keys to a truly musical performance from a loudspeaker is a minimalist, low order crossover.
No expense has been spared in reworking the Titan 808’s crossover, which features even higher-spec hand-matched Mundorf componentry, as well as now having the ability to be completely by-passed in order to facilitate ‘Aktiv’ operation using Linn Exakt technology (more on this below).
The 808’s minimal crossover is a two-and-a-half-way design, where the bass section in the lower cabinet is rolled off early in the frequency range; the mid/bass driver and tweeter are then operated as a two-way design. A slow roll-off from all the drivers ensures optimal coherence though the crossover regions.
Each speaker consists of an independent upper and lower cabinet, separated by precision-machined spacers and a port resonance guide. The upper cabinet houses the tweeter and mid/bass drive unit while the lower cabinet houses the two bass drivers. These are positioned in an isobaric arrangement, where the second driver is placed internally back-to-back with the first, designed to deliver a significantly improved bass response and minimise bass distortion. By separating the cabinet into two parts, the higher and lower frequencies remain unaffected by each other, preserving a remarkable clarity to the sound even at high volumes.
Considerable investment has been made in controlling panel resonance with a minimum of damping. The cabinets are made from a combination of high-density fibreboard laminates of different thicknesses. A triple laminate front baffle, profiled to improve dispersion, provides a solid mounting platform for the drive units to further eliminate vibration.
Both cabinet sections are port-loaded into the gap between them and are controlled by the port resonance guide. Venting the ports into a shared and controlled fixed boundary gap reduces port resonance and minimises phase error, producing a beautifully natural and life-like sound free from the usual issues associated with reflex designs.
The lower cabinet is attached to the plinth via a membrane to control energy transfer. The plinth itself provides the best possible grounding interface with very high-density fibreboard being combined with damping compound and a 5mm steel plate, into which precision-milled stainless steel spikes are fitted.
Internal wiring from The Chord Company has been carefully selected for its high quality musicality and resistance to the effects of vibration. In addition, Chord Company cables link the two cabinets, which are also fitted with WBT Nextgen binding posts to ensure a superb connection.
Kudos & Linn Exakt
Kudos Audio have been working with industry leaders Linn to bring the incredible performance of Linn Exakt to the Kudos range of loudspeakers. Launched by Linn in 2013, Exakt is a ground-breaking technology that allows the loudspeaker to be an intelligent, connected, software upgradeable product.
Exakt enables a wide range of performance- and personalisation-enhancing capabilities in design, in manufacture and in-home. In a system using a Linn Exaktbox, the original analogue crossover in the loudspeaker is bypassed and instead, the Exaktbox performs the crossover digitally, while applying Linn’s Exakt technology to eliminate distortion, correct for drive unit variation and optimise the loudspeakers’ performance for the room.
Kudos three top-of-range speakers, the Titan 808, Super 20 and Super 10 are all Linn Exakt-enabled.
