Revel Salon loudspeaker Measurements 2

Fig.4 shows the Salon's quasi-anechoic response, averaged across a 30 degrees horizontal window on the tweeter axis and spliced to the complex sum of the responses of the lower-frequency units below 300Hz. Under these conditions, the speaker's bass extension just fails to reach 20Hz, by a hertz or so. In a room, as LG found, the Salon will descend below 20Hz. There appears to be a slight lumpiness in the lower-bass/upper-bass integration region, but, again, this could well be a measurement artifact. (Calculating the true LF response of such a complicated speaker involves quite a lot of what engineers call "handwaving.") The speaker is astonishingly flat throughout the midrange, though there is a very slight lack of presence-region energy on-axis. Whether or not this will be perceived as adding a laid-back quality to the Salon's balance will depend on its off-axis behavior (see later).

Fig.4 Revel Salon, anechoic response on tweeter axis at 50", averaged across 30 degrees horizontal window and corrected for microphone response, with complex sum of the nearfield woofer, midrange, and port responses plotted below 300Hz.

Fig.5 shows the differences in the Salon's on-axis response due to the tweeter-level control being set to its "±1" positions. This can be seen to shelve the tweeter range up or down by almost exactly 1dB.

Fig.5 Revel Salon, effect of front-tweeter level control, set to "±1" and normalized to the HF-axis response (5dB/vertical div.).

When you look at the way in which the Salon's response changes to the sides of the tweeter axis (fig.6), you can see that there is a slight off-axis flare in the exact region between 3kHz and 4kHz where there is also a slight suckout on-axis. In normal-sized rooms and at normal listening distances, the Salon's perceived balance should be flat.

Fig.6 Revel Salon, lateral response family at 50", normalized to response on tweeter axis, from back to front: differences in response 90 degrees-5 degrees off-axis; reference response; differences in response 5 degrees-90 degrees off-axis..

These abominations are some of the worst speakers i have ever heard. That they are sold, let alone that the 'manufacturer' asks $15,000 per pair for theses abominations, is an insult to the human race.

Are you experiencing hearing problems? Probably the best speakers in the world!

These abominations sound like crap. My hearing is exceptional.

@Ornello :
You must not be familiar with Harmon Audio Group's testing facilities and procedures, and, you also must not have heard these speakers working properly. Either you heard some bad quality clones, or there was something terribly wrong with some other piece of equipment in the chain, or, very bad source material.

Because not only do these speakers measure exceptionally well from an entirely objective perspective, they also have EXCELLENT sound quality both from my perspective as a person who listened to them while working for a COMPETITOR -and- from the perspective of a panel of expert trained listeners working at the parent company.

Even if these speakers did not suit your personal preference [for non-neutral sound], I don't believe you honestly could have listened to them and come away with an opinion that the were not at least "generally excellent"!

In 2003 I went to all the major high end audio boutiques in Manhattan and auditioned several of their finest (and some more modest) speakers at each store. The Madrigal Revel Salon Ultimas stood out as clearly superior to every other pair we heard over that period of a couple days that we spend listening to the best the competition had to offer. Every other pair had at least some minor unpleasant quality to their sound, these were the only ones where nothing stood out as an obvious imperfection to their ability to accurately and dynamically reproduce recorded music.

When and where did you hear these? What is your favourite speaker system?

I own Yamaha NS-1000M speakers. Prior to that I owned Rogers Studio 1s. Either of these trounce the Revels.
