Davis Dufy HD Bookshelf speakers : Tear Down and Measurements

[daniboun]

Hi amigos

I wanted to share with you a little presentation of these bookshelf speakers that are little known to the general public... I haven't found much information on the web about these Davis Dufy HD speakers which are made in France.

I had the opportunity to get a pair for a small price so this is the opportunity to share some photos and measurements for the ASR community
I got the glossy black model in its high-end version.

I also took the opportunity to share with you some measurements taken using Room Analyzer II Pro and its calibrated microphone.

Not knowing these speakers at all, I am discovering the measurements and the entrails of the beast at the same time as you).
I admit to having been pleasantly surprised by the quality of the speaker cabinets with a parallelepiped shape to avoid standing waves, I don't know what really differs between the basic Dufy version and the HD version but the latter being more high-end especially with better components on the crossover... The Dufy HD is equipped with a well-known 5-inch Kevlar woofer, the Davis 13-KLV5A-R, I haven't found any information concerning the tweeter but seems to be a 25mm diameter soft dome tweeter.

My listening room

Now some measurements....
NB :


Ambient curve = Green > is supposed to show room interaction by gating the response to 8ms
Raw Curve = Yellow > Full FFT, information is displayed without any filtering. Everylittle detail, reflex and phase cancellation is visible
Anechoic curve = Blue > is supposed to remove room interference by gating the response to 4ms.
RTA : Real time Analyser, shows the frequency response in one place, with 1/3 octave resolution.

Thanks for the inside snoop!

I had to look this up about the software:

"three different types of curves: anechoic, ambient, and raw. The anechoic curve (blue in the above image) is supposed to remove room interference by gating the response to 4ms. The ambient curve (green in the above image) is supposed to show room interaction by gating the response to 8ms, and Raw is full FFT." From Audioholics review of Room Analyser Pro II.

Very interesting, in my main listening room I have a pair of Heco Victa 301 which have exactly the same shape as your Dufys and in the TV/living room we use a pair of much more basic Davis Hera 70s which suprised me with their very pleasant sound when installed. Davis describe the Hera as "Ce modèle est un produit polyvalent, qui peut à la fois servir de voies avant et arrière à un système home cinema de qualité, ou bien s’utiliser pour une écoute stéréophonique traditionnelle" (This model is a versatile product that can be used as both front and rear channels in a high-quality home cinema system, or for traditional stereo listening.)

Unfortunately Davis no longer manufactures the Dufy HD because it is too expensive to produce given the complexity of the cabinet. The Dufy 3D, which replaces the HD, has a fairly ordinary cabinet... The Heco Victa 301 has a fairly comparable shape, as does The Ceramic Mini Monitor below :

They don't make they Dufy 3D any more either - their speaker range is vast and confusing, very similar models with different names appearing and disappearing at random The good news is that with a bit of Googling it is fairly easy to find a pair of the size one wants at a bargain price!

You're right =)
In any case, if you find a pair for less than $300, it's a great deal!

German magazine Hifi Test also measured them:

Davis Dufy HD

Mir als passioniertem Lautsprecher-Selbstbauer ist der Name „Davis“ vielleicht eher geläufig als der Allgemeinheit. Chassis des französischen Lautsprecherspezialisten waren schon immer technische Leckerbissen – umso schöner, dass auch der Fertigboxenkunde davon profi tieren kann
