XTZ Divine 100.49 Tower Loudspeaker Measurements and Analysis

By Tarunvir Bains
The measurements were taken as per the Audioholics Loudspeaker Measurements Standard. 

Please note that frequencies below 500Hz are dominated by the room, NOT the speaker.  Since the measurements were NOT spliced with groundplane data, you're actually seeing the influence of the room for those frequencies.

XTZ Divine Frequency Response  (in-room @1 meter)

Give or take, sensitivity of the Divine Towers sits just around 92dB/2.83v at 1 meter. On-axis frequency response from the speaker shows roughly a +/-3db variation with a general dip in the mid-treble that helped keep the speakers well free of excessive sibilants. Response below about 400 Hz contains some boundary artifacts – it was very tough for me to remove the room from the equation when measuring such absolutely massive speakers. Based on this measurement, one could expect an overall soothing, yet forward presentation. I do feel that implementing an outbound crossover could get the response flatter and the driver integration tighter than the default passive design, but you would need to find someone capable of setting it up as doing so is truly a science.

Listening window response
(in-room @ 1 meter)

The listening window response shows the general response in the forward direction at angles correlating to typical seating positions. You can identify the crossover region in the bottom curve (15 degrees vertical above the speaker) as the dip in response in the upper midrange. Give or take, the horizontal response is mostly symmetrical, as the loudspeaker layout is symmetrical. The majority of the response stays within a roughly +/- 3 dB window.

XTZ Impedance 

XTZ Divine Tower Impedance vs Frequency

The XTZ Divines are a true 4 ohm load which is usually to be expected of any speaker with a dual woofer configuration, particularly a 3-way configuration. The electrical phase angle is never a problem so most amplifiers will be comfortable driving these babies – but do have the current on-tap for when it's needed. With their medium-high efficiency I got them pretty loud with my Crown Amp.

XTZ Divine Tower Harmonic Distortion @ 89db @ 2m

This is absurdly low. We are talking class-leading performance here. In fact, I don't even think these results are entirely accurate, as I suspect what was recorded was just the distortion in my amplifier as well as background noise. XTZ can pat themselves on the back for a well-engineered speaker in terms of non-linear distortion.

XTZ Divine Tower Cumulative Spectral Decay

CSD, or Cumulative Spectral Decay, is a three-dimensional plot derived from the loudspeaker’s impulse response which can highlight issues. There's some minor ringing in the waterfall plot, but it's very low in level. My guess is that it's from the cone breakup mode of the aluminum woofers and could only be avoided with a more aggressive crossover. This is something an active crossover could make “look nicer” but I'm not sure if there's any audible consequence to it – not any I observed, at least.

The amplification used in this review leaves a lot to be desired.

Any Divine (either floorstander or stand mount) owners within driving distance of DC who'd be willing to offer a prospective buyer an audition? These beasts weigh enough that I'd prefer not to sign up for an in-home audition, though I do appreciate XTZ's policy.

I get that those here take GranteedEV's review as largely favorable. Later, when I have more time and finish licking the rib sauce of my fingers, I'll give you another take. Mind you, I did follow the deleted thread which if you didn't gives me a different perspective.

Sounds juicy - both the ribs and the deleted thread.

I don't consider it a cover.

I've owned and heard a lot of speakers in the same room & setup. I would have a difficult time reviewing them all and trying to come up with many different adjectives.

The simple truth is that there are a lot of great sounding speakers. I like a lot of them. So when I say that, I mean it unequivocally, not as a cover or trying to be PC.

I am sure GranteedEV and many reviewers feel the same.
Certainly and these may fall into that class of decent speakers. Over at Stereophile, the reviewers are generally the ones who pick what they want to review. They may have had prior experience, some familiarity that goes beyond catching them at a show, or there's something truly unique that bears further critical examination. In the case of other reviewers, they're assigned speakers to review. Big difference but some similarities in that both camps look to put somewhat positive spins on things, emphasizing this while down playing that, finessing their perceptions with a subtle use of phrases such as not to offend. Politically correct. So you have to read between the lines. Determine if the vendor is generally inept. But if one runs their review past the vendor first, are they serving the public or themselves and the vendor?

Sure one can say we all hear differently and have different priorities. A position like that also provide cover and be looked at as a politically correct view that seeks to offend no one.
