Discovery 3Zero

Fibonacci Series 2.5-Way Standmounted Loudspeaker

PUNCHY.ACCURATE. LIGHTNING FAST.
ENDLESSLY CAPTIVATING.

The third generation of a Wilson Benesch classic. The original ‘Discovery’ name was a reference to the development of the unique acoustic presentation that the first Discovery loudspeaker delivered when it was launched in 2002. A 2.5-way standmount monitor like no other, the Discovery 3Zero deploys the same unique drive topology as the original classic, placing the Fibonacci Tweeter and a dedicated Tactic 3.0 midrange drive unit in close proximity to the powerful Isobaric Drive System that sits directly on the underside of the loudspeaker in the vertical plane. With all drive technologies placed within a few inches of one another, time alignment and integration across the Discovery 3Zero frequency band is unmatched. The Discovery 3Zero delivers a lightning-fast, punchy, highly accurate and endlessly captivating presentation.

DESIGN

TACTIC 3.0 DRIVE UNIT

The structure at the centre of the diaphragm plays a critical role in the behaviour of the drive unit. Commonly referred to as the “dust cap”, the name understates the importance of this component. In the Tactic 3.0, Wilson Benesch added the Fibonacci Element.

Produced in house using additive manufacturing technology, the Fibonacci Element can be printed according to pre-designed parameters. Such is the precision of the additive manufacturing software, that the Wilson Benesch design team can see in cross-section and design three-dimensionally the optimal layup of carbon fibre and nylon, defining both stiffness and weight across the structure. The result is a new geometrical form that is comprised of a double curvature with both open and closed aspects in the form of a lattice structure again borrowed from natural geometry. 5 different materials and adhesives provide significant improvements in both the accuracy of the frequency response and the reduction of distortion.

This is a critical aspect of the relationship between the drive unit and its ability to integrate with the roll off of the tweeter and bass drive units. In the past, several materials have been drawn upon to enable the fine-tuning of this marriage. Additive Manufacturing has opened up a new chapter in the pursuit of this subtle but extremely important aspect of loudspeaker design. For the first time, the principal aspects of this structure can all be adjusted in a way that was previously impossible.

FIBONACCI SILK-CARBON HYRBRIDISED TWEETER

The latest iteration of Wilson Benesch tweeter technology builds upon the Semisphere tweeter design pushing it into the next generation. As with all Wilson Benesch designs, the advances of the previous generation are built upon an iterative research and development pathway. With the Fibonacci tweeter, advances have been made within the structures adjacent to the motor and the hybridised dome. The Fibonacci tweeter faceplate is formed from a carbon fibre - nylon composite structure creating a geometrically optimised structure - the Fibonacci Element - that has been inspired by sacred geometry found in nature. In terms of acoustic performance, the faceplate delivers a new benchmark in terms of flat frequency response and ultrawide dispersion. In addition, the Fibonacci Element is decoupled from the motor and tweeter chassis which almost entirely eliminates structural borne resonance within this critical structure that surrounds the tweeter dome.

SSUCHY BIOCOMPOSITE MONOCOQUE

The Fibonacci Series introduces a full line of loudspeakers from the Wilson Benesch brand that are built from the new A.C.T. 3Zero biocomposite Monocoque. The new monocoque marks significant advances not only in terms of the acoustic performance of the Wilson Benesch reference line, but it also represents a deliberate and conscious move toward natural, renewable and sustainable materials technology.

ISOBARIC DRIVE SYSTEM

The principal low-frequency load of all loudspeakers in the Fibonacci Series is delivered by the Isobaric Drive System. Here two Tactic 3.0 Drive Units combine to create an Isobaric Drive System. The Isotactic Drive System is responsible for reproducing an incredibly tight and controlled bass response that is perfectly integrated with all other woofers in the loudspeaker chassis, particularly the midrange Tactic 3.0 drive unit.

Works well, but is now too expensive...
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
The "No added sweeteners" has been my go-to version of Metamucil, but I'm giving it 4 stars and moving on to another brand as the price is over $35 which is too much imo...

I like the mildly tart taste of this unflavored, unsweetened drink made up with water.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.

Definitely Not Unflavored. This is Tart / Sour, Which Limits the Options to Certain Juices
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was expecting an unflavored fiber powder. However, expect a sour/tart taste. This means you can't add it to tea or coffee. I don't think it is appropriate to say that it is "unflavored" as I've had psyllium husk from other vendors that are truly "unflavored" (i.e. no citric acid). Dextrin (another fiber source) is also unflavored. But this Metamucil is tart (like sucking a lime) and can only be added to tart juices like orange juice or lemonade.

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Fantastic product, dont like the texture - mix with food. Still 10/10 💩🎉
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Taste: While the product doesn’t taste bad, preparing it as directed results in a very mild orange flavor. -as a drink I would prefer more flavor. Texture: The psyllium husk absorbs water extremely quickly—even in cold or room-temp water—which is just the nature of the ingredient itself. Because it starts to gel so fast, you have to chug it, and even then it can be difficult to get down. (I personally gag at it, but I have sensory issues) If the gel like texture is an issue for you, I found it more palatable mixed into food with water on the side. Texture aside, the product itself is highly effective. Mixability: It doesn’t always mix smoothly and tends to clump. Again nature of the ingredient not the brand. The powder is very fine and non-gritty perfect for other mixings. Side effects: I had uncomfortable bloating the first time (2 scoops/ full glass), I recommend starting with (1 scoop or less/full glass) Dont rush it. Increase it from there as you grow tolerance. You may feel very full. - it helped me eat less!
