The THE15 Be PRO PASSIVE ON WALL is an extremely impressive and extraordinary performing musical speaker system, that leaves nothing to be desired.

This 15"point source axisymmetric speaker has been designed as screen speaker for large theatres as left, centre and right speaker or can be used for very large theatres as a surround speaker.

ASCENDO's passive crossover technology paired with highest grade flat wound OFC copper air core coils and silver capacitors work in combination with the enclosure and coaxial driver design to deliver ultra-precise and incredibly fast impulse response.

Each channel of the THE15 Be PRO PASSIVE is capable of incredible SPL levels, but also the more impressive dynamic contrasts from whispering dialogues to explosive effects. The volume ranges your home theatre speakers need to be able to handle without audible distortion is huge, especially if you look for a reference level director’s cut performance - this level difference from softest to loudest sounds is called ‘dynamic range’. The THE15 Be PRO PASSIVE reproduces every possible dynamic range with ease. Even the most complex film passages with extreme dynamic requirements are reproduced at the highest clarity and lowest distortion. Imagine a life-like drum solo rendered exactly to the point by hearing and feeling the tremendous dynamic leaps of a bass drum and snare, while at the same time the humming of the cymbals fading away airily into the dark silence of the room giving way to the tiniest fine details.

This very precision lets the listener immerse entirely into the direct and intense visual action. Whether film or music – this sonic experience is not distinguishable from reality anymore.

The expertly engineered Beryllium compression tweeter is centrically arranged in the back of the 15-inch mid-woofer unit. In concert with the passive crossover, their results merge perfectly and allow for a time and phase-coherent lifelike reproduction of all acoustic events with reference level in every seat. The brain can therefore relax and stop trying to process the timing and phase errors far too common in other speaker designs.

Combined with our PRO and Infrasonic subwoofers you will experience unimaginable realism of sound paired with sheer limitless dynamics.

The15 Be PRO PASSIVE On WALL – The realistic cinema experience

Beryllium (Be)

Although it is one of the most expensive materials used to make speaker diaphragms, in terms of stiffness-to-weight ratio, Beryllium is the highest of any known metal and can deliver dramatically superior results when properly incorporated into a speaker design.

The speed of sound through Beryllium is nearly 2.5 times faster than the speed of sound through aluminium or titanium. This means the first breakup will occur at a much higher frequency—well outside the audible range. Breakup occurs when the cone partially vibrates at certain audible frequencies and therefore isn’t entirely pistonic throughout its range. This leads to non-linearities in the amplitude response as well as stored energy in the time domain.

It is precisely these characteristics that give Beryllium speakers the ability to reproduce amazing detail and provide sound clarity with the absence of resonances.

You must be wondering, what does all this mean to me as a user?

It means, that even the finest details are all there.

It must be experienced to be believed.

Top quality tool that improves espresso extraction
Color: Gray
Fantastic and easy to use. Stand sits on top of espresso machine and the WDT tool is always ready, no unscrewing. Upgraded from a screw-shut version and couldn't be happier. Comes with extra needles which I hope to never need. Easy to recommend

Makes a difference but maybe only to caffeine addled coffee snobs
Color: Black
I won't say that everyone urgently needs one of these. This is helped me up my game. Perhaps not absolutely necessary, but it noticeably reduces canalization and improves extraction. And it appears to have improved not only my espresso, but my pour-overs and my Mokapot (especially the Mokapot!). It's a little fiddley to assemble - there's sets of springs and needles - but once you get it all locked down, its very tight. There's a set of spares - I can't imagine needing them. The tool kinda sits in the weighted base, but it appears to stay put in my cabinet.

WDT Tool: The Needle in My Espresso Haystack
Color: Black, Color: Black
I kind of went down a deep dive researching these WDT (Weiss Distribution Technique) tools, and I have to say, this one hits the sweet spot! The needle size is just right, and the shape is spot on for what I need. Plus, it’s a nice perk that you can remove and replace the needles. I’ve tried using needles and bobby pins in the past, but they were too thick and just ended up creating their own channels—talk about a brewing disaster! Now, here’s the twist: even though it comes with seven needles installed (and more replacements), I find it a bit overkill. With all those needles, it just traps the grinds in the center, pushing stuff around like it’s playing a game of “don’t let the coffee escape.” So, I stick with just three needles in a triangle formation for optimal distribution. Pro tip: don’t forget to adjust the depth as you use it to ensure you’re getting the best coverage of your coffee grounds! The build quality is actually pretty impressive. It feels like well-constructed metal components that could survive a small espresso war. Plus, it's more affordable than some of those fancy options out there—because who needs a second mortgage for great coffee? It looks quite nice on my counter, and the little stand is a handy extra touch. Overall, if you’re looking to up your espresso game and avoid the chaos of uneven distribution, this WDT tool is worth considering. Just remember: less is sometimes more when it comes to needles!
