Signature Theta Speaker: A Design Inherited from the Magellan Series

Built with high-density cabinetry, directly inherited from the prestigious Magellan series, the Signature Theta speaker stands as a masterpiece of design and craftsmanship. This high-end cabinetry not only offers a stunning aesthetic but also contributes to the exceptional sound quality of the speaker. The “Piano Lacquer” finishes give this speaker an undeniable elegance that catches the eye at first glance.

Transparent Sound Power

Don’t be fooled by its compact size, as the Signature Theta speaker possesses impressive sonic potential. Its ability to deliver exceptional clarity in the midrange and captivating depth in the bass sets it apart remarkably. Thanks to its 16 cm midrange-woofer with a half-roll suspension and paper cone, this speaker can reproduce human voices and acoustic instruments in an extremely natural manner. The result is a sound experience that transports you to the heart of the music, capturing every nuance with precision.

Performance Tailored to Your Space

The Signature Theta speaker is designed to adapt to different sound environments. Recommended for rooms with an area of 15 to 30 square meters, it is perfectly suited for discerning music lovers who are looking for a compact speaker that delivers exceptional sound quality. Moreover, it can also be used as an effects speaker in Home Cinema configurations, offering an immersive audiovisual experience.

Exceptional Musicality at Your Fingertips

The Signature Theta speaker pushes the boundaries of what is possible in terms of audio performance. Its midrange driver with a paper cone offers unparalleled sonic transparency, allowing for faithful reproduction of the subtleties in music. Furthermore, thanks to the optimization of the SIGNATURE die-cast aluminum basket, the midrange driver offers improved voice coil ventilation, resulting in a more precise and detailed sound response.

The Art of Sound Reproduction

Whether you are a seasoned audiophile or simply a music lover, the Signature Theta speaker promises an extraordinary listening experience. Its design features, high-quality components, and meticulous attention to detail make this speaker a wise choice for those seeking balanced and immersive sound reproduction.

Horn Tweeter: Immersive Listening Without Distortion

The tweeter is one of the key elements that sets the Signature Theta speaker apart. Equipped with the TZ2500 tweeter featuring a 25 mm titanium dome, this speaker brings a new dimension to high frequencies. The die-cast aluminum horn, inherited from the Magellan program, ensures exceptional dispersion of high frequencies, offering better perception of details and enhanced finesse. The improvement of the cavity behind the tweeter helps reduce distortion, ensuring a crystal-clear and immersive sound experience.

Enhanced Rear Wave Management

Another important aspect of the horn tweeter design is the management of rear waves. In the case of the Signature Theta speaker, the tweeter is semi-baffled, which means it is partially isolated from the rear waves generated by the speakers. This ingenious configuration minimizes unwanted acoustic disturbances, thus ensuring clear sound reproduction free from distortion.

Because the small Triangle Titus EZ, a musical marvel, impressed me so much, I wanted to experience more of these "Triangle capabilities."

My research led me to the Triangle Signature Theta and an unbeatable offer from HomeCineSolutios. Just 3 days after placing my order, they arrived.

I let them run continuously for 150 hours. After that, I was at the end of my rope. The Theta simply did not want to sound good. Anemic, lacking juice and power.

I decided to return the Theta while still within the cancellation period and prepared them for shipping.

A very restless night followed. A thousand things went through my mind. Had I really tried everything? Had I given them enough time? Was I doing something wrong? I was truly desperate.

The next morning, I decided not to return them and to see it through.

Another 100 hours later, they now sound simply fantastic. They rock and whip the sounds around my ears as if there were no tomorrow. Magnificent!

The Theta need a very, very long break-in period!

I suspect that it is mainly the capacitors in the crossover that need this time.

Hang in there and occasionally really crank them up. If you think it is not going to work, it is not the Theta but your patience. You should give them 250 hours. Write it down so that you do not give up too soon. You will definitely be rewarded!

The Theta can do everything. Dynamic, loud and sensually quiet, with lots of feeling and clarity. When needed, also with a full-grown bass that makes a subwoofer unnecessary.

Position them precisely. It should be an isosceles triangle. The listening distance (min. 3 m) should be significantly greater than the distance between the speakers. Toe them in only slightly.

The Theta absolutely have to stay and work their magic with my Klipsch Cornwall and the Titus on tube amplifiers.

Music makes you happy and is worth every effort. Thank you Triangle and thank you HomeCineSolutios.

Da mich die kleine Triangle Titus EZ, ein musikalisches Wunderding so begeistert hat wollte ich mehr von diesen "Triangle-Fähigkeiten" erleben.

Meine Recherchen führten mich zur Triangle Signature Theta und ein unschlagbares Angebot zu HomeCineSolutios. Schon 3 Tage nach meiner Bestellung waren sie da.

Ich ließ sie ohne Unterbrechung 150 Stunden laufen. Danach war ich mit den Nerven am Ende. Die Theta wollten einfach nicht klingen. Blutleer, saft-und kraftlos.

Ich beschloss die Theta noch während der Widerrufsfrist zurück zu schicken und bereitete den Versand vor.

Eine sehr unruhige Nacht folgte. 1000 Dinge gingen mir durch den Kopf. Habe ich wirklich alles versucht? Habe ich ihnen genug Zeit gegeben? Mache ich irgendwas falsch? Ich war richtig verzweifelt.

Am nächsten Morgen habe ich beschlossen auf einen Rückversand zu verzichten und die Sache durchzuziehen.

Nochmals 100 Stunden später spielen sie jetzt einfach fantastisch. Sie rocken und peitschen mir die Klänge um die Ohren als ob es kein Morgen gäbe. Grandios!

Die Theta brauchen sehr sehr viel Zeit zum einspielen!

Ich vermute das hauptsächlich die Kondensatoren der Frequenzweiche diese Zeit benötigen.

Durchhalten und ab und zu mal richtig Gas geben. Wenn Du denkst es wird nichts liegt's nicht an der Theta sondern an Deiner Geduld. 250 Stunden solltest Du ihr Zeit geben. Schreib es auf damit Du nicht voreilig aufgibst. Dann wirst Du garantiert belohnt!

Die Theta kann Alles. Dynamisch, laut und sinnlich leise, mit viel Gefühl und Überblick. Bei Bedarf auch mit einem erwachsenen Bass der einen Subwoofer überflüssig macht.

Stell sie exakt auf. Ein gleichschenkliges Dreieck sollte es sein. Der Hörabstand (min. 3m) und deutlich größer als der Abstand zwischen den Lautsprechern. Nur leicht einwinkeln.

Die Theta muss unbedingt bleiben und mit meinen Klipsch Cornwall und den Titus an Röhrenverstärkern zaubern.

Musik macht glücklich und ist jede Mühe wert. Danke Triangle und danke HomeCineSolutios.

In the past, I owned Monitor Audio speakers from the Silver to the Platinum series, as well as B&W 805D4 and 803 D4 (which didn’t impress me at all). After that I had Canton Reference 5K and Reference 7.
I wanted to switch to bookshelf speakers. I first fell for the beauty of the Triangle Signature Theta and decided to go for it, telling myself we’d see how it goes.
At this point, they’re still breaking in, but they sound wonderful. The sound fills my entire living room (30 m²) without any problem. A wide soundstage, very dynamic speakers but not tiring to listen to. They’re paired with a Sugden IA4 amp.

Par le passé, j’ai possédé des enceintes Monitor audio de la silver à la Platinum, B&W 805D4 et 803 D4 ( qui ne m’ont pas du tout impressionné). Ensuite j’ai eu des Cantons référence 5 k et reference 7.
J’ai voulu passer à des bibliothèque. J’ai d’abord craqué devant la beauté des Triangle Signature Theta et je me suis lancé en me disant on verra bien.
À l’heure qu’il est, le rodage est toujours en cours mais elle sonnent merveilleusement. Le son remplit tout mon living (30 m2) sans aucun problème. Une image large, des enceintes très dynamiques mais pas fatiguantes. Elles sont associées à un ampli Sugden IA4.

Really a big step up from the Comètes, designed and manufactured in France, as well as tested, not very far ultimately from the Duetto Magellan, except for the bass, a very beautiful product for those who like Triangle, with highs that are not at all harsh, use with Yamaha RN2000A
