Dynaudio's Ultimate Consequence

I thought I was seeing a familiar sight when I went into the RMAF room shared by Dynaudio, Wadia, and XLO. The loudspeakers, driven by humongous Octave monoblocks, appeared to be larger versions of the Accent 3 that Dick Olsher reviewed for Stereophile in the 1980s. There were more drive-units but as in the earlier design, the tweeter was placed at the bottom of the front baffle. This is the Consequence Ultimate Edition ($70,000/pair) explained Dynaudio president Wilfried Ehrenholz. The original Consequence was launched as the Danish company's flagship 25 years ago at the then astronomical price of 30,000DM/pair and has sold some 2500 pieces since then, even though it was not promoted in any major way after the mid-1990s.

The Ultimate Edition is a thorough reworking of the Consequence for the 21st century, Although it it looks similar to the original, it is 2" taller and 30% heavier, and the drive-units are new, featuring Dynaudio's Esoter2 technology. The beautifully finished enclosure comes in three sections, the lower-front module carrying the midrange and treble array, the other two forming an inverted "L," with one of two 12" woofers mounted on its front. A second 12" woofer is mounted at the top of the rear module fires into the interior of the top volume, forming a compound or "isobaric" system, where the primary woofer operates with constant back pressure on its cone, extending its response below what would have been its air-suspended resonant frequency. The inner woofer is loaded with a long port firing downward, and the system is specified as being linear to 17Hz!

The unusual array of upper-frequency drive-units places each unit farther away than the one next lower in frequency from the ears of a seated listener, which, in effect, time-aligns their outputs, allowing Dynaudio to use primarily first-order crossover filters. The sound of a familiar Patricia Barber track was effortlessly natural and uncolored, but I couldn't escape the impression that I was looking down on the singer from the concert-hall balcony rather than up at at her from the stall seats.

your impression doesn't make sense. you were clearly letting your eyes influence you. the tweeter and upper frequency drivers have wide enough dispersion that i don't think makes this possible. it's deliberately done this way to time align the drivers naturally without having to set back the drivers. let atkinson test and i'm sure this is the case.

The PHC of The Ultimate Consequence

In a demo of this speaker in Copenhagen (I believe in 2009), The Ultimates were being driven by The Big McIntosh labs 1200W MC2KW's. Although the specs on the Speaker says it handles 400W, The Demonstrator did a close-up of the meters on the McIntosh Amp and the meters were pegging into the 1200W range for more than a few seconds. My question is: how is this possible? In addition, the sound was incredible.
