SETTING A NEW STANDARD
We recognize that discerning audiophiles demand nothing but the best, and that's why we are excited to unveil the Trohet R Upgrade Path. This is your gateway to an entirely new realm of sonic brilliance, a journey that is set to redefine your audio experience.
The Trohet R, our latest masterpiece in the world of high-end audio, has been meticulously designed for those who demand nothing short of audio perfection. It takes the core philosophy of the original Trohet and catapults it to an entirely new level of distinction. This is not just an upgrade; it's a transformative experience.
The Trohet R is the epitome of audio perfection. By incorporating the Scan Speak R2904 tweeters, it delivers unparalleled accuracy and clarity. Each note, every instrument, and all lyrics are brought to life in a way that you've never experienced before. The Trohet R doesn't just reproduce sound; it immerses you in it.
PATH TO SONIC PERFECTION
By replacing the crossovers and tweeters, you'll experience an instant transformation in your audio quality, reaching unprecedented heights.
BUILDING THE TROHET R's
To upgrade your Trohets to the Trohet R, you simply need to recess the tweeter cutout by an additional 2.5mm, replace the crossovers, followed by installing the new R2904 tweeter and reinstalling the 15W/8530 woofer.
The crossovers in the Trohet R are notably more intricate compared to the existing Trohet crossovers. If you're not comfortable reading circuit diagrams, we recommend having us assemble the crossovers for you. This option can be selected during the checkout process. The pre-built crossovers come tagged, making it clear where each wire should connect.
The most straightforward method to adjust the tweeter cutout depth is by using a router equipped with a ball-bearing cutter and a jig featuring a 104mm hole cutout. If you'd like us to provide the jig and router cutter, please select this option at checkout for added convenience.
The tweeter hole needs to be deepened by 2.5mm to account for the thicker faceplate of the R2904 tweeter.
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."
"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."

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.
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 bespoke all-pass filter 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 response 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 $10,000 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.
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.
TWEETER FACEPLATE OPTIONS
The Scan Speak R2904 tweeter is available in either black or silver anodized aluminum.
THE TECHNICAL SPECS
The Trohet R's are designed for critical music listening and well suited for general music enjoyment.
To get the most of these speakers, we recommend an amplifier that can provide 50 to 500 watts of clean power. Please contact us or see our blog post if you're unsure about amp choice.
2 Way Design
Ported enclosure (rear-firing port)
Power handling: 100 Watts
Frequency Range: 45 Hz - 30 kHz
Sensitivity: 84 db @ 1 Watt
Impedance: 8 ohm nominal
Dimensions: 36.5 cm high, 18.5 cm wide, 28 cm deep
Number of speakers in the kit: Two
Suitable for both far and near field listening.
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.
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.
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.
