Marc, you couldn't wait for another year to celebrate 21 years like DEQX did ?? Seriously LOL

Halcro & Duntech & Döhmann
The best of Australian – maybe the best in the world!
This unmissable audio suite will host Duntech's brand-new Princess loudspeakers – $120,000 floorstanders that take their lead from the company's legendary Sovereigns, acknowledged by experts as the most accurate in the world. With the drivers symmetrically arranged on a vertical axis and time aligned, you have to hear these speakers!
The power comes from Halcro's very latest reference amplification, a triumph of form and function, unique in its imagination of what an amplifier is and how to puh the boundaries of technology.
The third Aussie legend is analogue playback courtesy of a Döhmann Helix turntable, engineered to deliver unparalleled performance in analogue playback and is the result of many years of research, development, collaboration and listening by internationally acclaimed analogue designer Mark Döhmann and his team.
It's an Australian supersystem not to be missed!
QuoteIn consumer speakers where crossover slopes of typically 12dB/octave are used, the same sound is coming from both drivers, typically for an octave above and below the crossover frequency. Unless these sources are perfectly timed to meet in phase with each other (time aligned), the resulting mix of sound will produce 'comb filtering', which can sound 'nasal' or 'flanged'.
Another problem has also been introduced by using multiple drivers to reproduce sound – a single instrument may now sound like it is coming from different places. This results in poor off-axis performance because varying degrees of summation and cancellation occur depending on the relative distance between each driver - a phenomenon known as 'lobing'. Because the woofer is often physically placed further back than the tweeter, this lobing is also non-symmetrical in the vertical plane. The loudspeaker's off-axis performance is important because although this is not necessarily what is heard directly, it is ultimately heard because of its coupling into the room.
QuoteTHE DEQX SOLUTION
The active DEQX crossover and correction processors provide help to resolve the problems mentioned above at a number of levels. Although impractical even in 'active' analogue crossovers, DEQX provides true linear phase very high-order crossovers that provide absolutely precise time alignment and phase coherence between drivers, while limiting the 'bleed' of similar frequencies over the crossover region so that lobbing effects occur only at the imperceptibly narrow crossover region, and dispersion patterns remain similar between drivers.
QuoteSecond, what I really like about my DEQX crossover at the moment is the implementation of linear-phase crossovers (FIR). The software treats it just the same as Linkwitz or Butterworth crossovers. Just choose it from the list, that simple. All other DSP solutions so far expect you to be a DSP expert to be able to implement linear phase crossovers. I was looking for this in audioweaver but so far have not found it yet. Maybe I'm missing something. Now before anyone likes to discuss the downsides of linear phase crossovers and why I would want them but there is only one simple answer: Because it sounds better in my system and except from linear phase crossover I can't think of anything why I would need the amount of DSP power that is on offer in the Ultimate Preamp

This unmissable audio suite will host Duntech's flagship Sovereign loudspeakers – acknowledged by experts as the finest in the world, certainly the most accurate, a seven driver system with the drivers symmetrically arranged on a vertical axis and time aligned.
