SETTING A NEW STANDARD

The Trohet R, our latest masterpiece is tailored for those who demand nothing less than the absolute best. It builds upon the core philosophy of the Trohet but propels it to an entirely new echelon of distinction.

Designed for individuals who are uncompromising in their pursuit of perfection, the Trohet R caters to a select audience. It's a testament to what's possible when you seek the ultimate in audio quality. There are very few stand-mount speakers that come close to the performance of the Trohet R.

 

The Trohet R is now available as a kit and complete speaker builds. If this is your first-time building speakers, we recommend that we build the crossover for you - the remaining parts of the speaker build is simple and is easy to complete by following the included video instructions.

TSP VS AUDIO INDUSTRY

The True Value of DIY


Buying speakers at your local hi-fi store may seem convenient, but you pay at least 2-4 times more for the same performance compared to our kits.

While the hi-fi industry typically operates on margins of 60%, and even higher for super high-priced equipment, our net margin is just 25%. We aim to be honest and fair, providing a world class speaker at a fair price.

TESTIMONIALS

"Hi Atlas

The upgraded Trohets (R) got a fair work out over the weekend, mostly with vinyl.  I played everything from Elvis and Aretha Franklin, TOOL, Daft Punk through to Miles Davis and Tash Sultana.  What stands out is the silence/separation between the instruments and vocals.  Its breathtaking.  It draws you deeper into the music almost as though it’s the first time you have heard the song.  

Very happy with the upgrade and would recommend it to anyone who is interested."


Phillip Manczak

"I recently purchased and built a Trohet R system. Well, before that I built a regular Trohet system which was simply incredible. I used zebrawood for that one.

But then The Speaker Project released the R and I was hooked. I built them out of Wenge using pre-assembled crossovers. The sound is stunning. The tweeter is oh so sweet. It's hard to describe really... best I can say is there is a crispness and tightness to the sound. The base is exceptional but not overpowering. Atlas was so helpful and no question was to hard to answer even while he was on holiday in Europe. I do realise these are costly, so I am happy to offer anyone in Sydney a listen before you buy. I am based in the Bondi Junction area. Atlas can provide you my details."

 

Kevin Sher - Google reviews

Out of any I’ve ever owned, have just blown me away for their crystal clarity, depth and warmth of sound - they colour the music just as I imagine the artist would want it to be heard.

 

Thank you Atlas for introducing me to an amazing new listening experience. These speakers are for life.

WARM YET DETAILED

In a high-end audio landscape increasingly dominated by overly bright and analytical sound signatures, the Trohet R stand out by prioritizing a different approach.

 

Their exceptional ability to blend superlative detail with a warm, inviting sonic character sets them apart from the crowd. 

 

Many enthusiasts describe feeling as though the music is enveloping them, a testament to the speakers' capacity to convey the emotional essence of the music while maintaining precision and clarity.

This delicate balance between detail and warmth ensures that listeners can indulge in extended listening sessions without succumbing to fatigue.

 

As a result, one can experience the immersive nature of music while appreciating its subtleties with unparalleled depth and richness.

THE REVELATION

At the heart of the Trohet R lies the Scan Speak 15W/8530 woofer and R2904 tweeter, both from the esteemed Revelator line. 

These two drivers are some of the best ever produced, providing exceptionally low distortion and wide bandwidth. For good reasons, these drivers are found in some of the world's most expensive speakers. 

But good drivers are only as good as the crossover design. For that, the Trohet R employs a state-of-the-art passive circuit. Scroll down to learn more.

PASSIVE FILTER

The Trohet R features a meticulously crafted passive crossover network that fine-tunes the speaker's acoustics to deliver an incredibly natural sound profile.

The crossover is a sophisticated assembly, comprising 8 capacitors, 7 inductors, and 8 resistors for each speaker. To further enhance performance, the woofer circuit incorporates two resonant dampening circuits that effectively address baffle step and cone break up nodes.

The tweeter circuit is equally noteworthy, utilizing a second-order filter. A sophisticated time correction network has been thoughtfully integrated to achieve precise time correction between the woofer and tweeter. This critical adjustment enables seamless acoustic summation with gentle slopes on a flat baffle, resulting in an accurate power response and a naturally balanced in-room sound for fatigue-free listening.

CHALLENGE THE STATUS QUO

The Trohet R speakers are the epitome of high-end audio excellence, but without the astronomical price tag.

 

While many high-end brands charge over $10,800 for speakers of this caliber, building the Trohet R allows you to challenge the status quo, offering uncompromising audio performance at an accessible cost.

But let's be clear, you're not just saving money; you're delving into an immensely rewarding experience that earns you the ultimate bragging rights.

DEEP BASS 
COMPACT CABINET

The Trohet R's rear-ported design strategically enhances bass performance, yielding well-defined low end within a compact cabinet.

 

Simultaneously, it mitigates port noise, ensuring distinct bass quality at elevated volume levels for an immersive listening experience.

LITTLE GIANTS

Once you've welcomed into your hi-fi setup, you'll understand that the Trohet R is the only speaker you'll ever need, delivering a level of audio immersion that's truly unparalleled.

What sets it apart is the pinpoint imaging and remarkable clarity, leaving you to question the necessity of larger speakers. The Trohet R's sonic excellence speaks for itself.

BUILDING THE TROHET R's

The Trohet R is a beast of a loudspeaker design, and at its core lies the intricate heart of complexity – the advanced crossover. If you're seasoned at building electrical circuits, you're good to go. But if this is your maiden voyage into the world of electronics, we've got you covered. We recommend letting us handle the crossover construction for you, ensuring that every component hums in perfect harmony.

The remaining parts of the speaker build is simple; the included video instructions guide you through the process, so you know where everything is is meant to go. 

Should you have any questions along the way then feel free to give us a call or reach out via email. 

EVERYTHING YOU NEED IN A SINGLE BOX

One of the complex parts of building speakers is sourcing the correct parts - we simplify it by providing it in one neat box.

Check out what's in the kit below.

REFERENCE FREQUENCY RESPONSE

The TROHET's have a frequency response of +-2 dB between 100-20KHz. The frequency range below 700 hertz is 1 dB above the median response level, which provides warmth and body for musical enjoyment. 

SPL

THE INVERSE RESPONSE

 

This graph shows the response when the tweeter is measured 180° out of phase. The deeper the "null", the better the phase tracking. Phase is an often-overlooked part of speaker design, where many just focus on the frequency response. In my experience, a speaker is only great when both phase and frequency are optimised.

IMPEDANCE RESPONSE

The graph also shows the impedance response,  which demonstrates a moderately easy speaker to drive, it may not be suitable for all tube amps, but any solid state will be able to drive these speakers. The key features of the impedance response are detailed below;

  • The ported cabinet tuning frequency is shown to be 39 Hz.

  • The nominal impedance is 8Ω between 1Hz - 20kHz.

  • Max impedance of 26.85Ω @ 71 Hz.

  • Min impedance of 5.05Ω @ 383 Hz.​

  • Max electrical phase shift of 40° @ 774 Hz.

  • Min electrical phase shit of -52.31° @ 90 Hz.
