Test Speaker Stereo – From the eros of sound

But that was also time again, time for men’s boxing: big, strong and wide and with a horn on top. Only the name, the irritated a bit, because he clearly signals: Here, there is except a lot of dynamics and sensual euphony

Thivan Labs? Have you never heard of it? Well, me neither. This is not a big offense now, because the manufacturer comes from a completely different corner of the world, namely Vietnam. And that, in turn, makes sense, because in this faraway country a kind of hi-fi boom seems to have broken out – at least, if I go after the pictures posted by my many new Facebook friends with new and old hi-fi technology; unfortunately I can not read the lyrics. Thivan Labs claims to have been on the market for 10 years and now presents the Eros-9 Anniversary, the first loudspeaker to prove its worth on the German market. Eckhard Derks from TCG-Vertrieb deserves the honor to have discovered this highly interesting sound transducer and made it available to us. To return to my Facebook friends: Their plant pictures show a tendency towards the traditional HiFi of bygone days, ie small tube amplifiers and large loudspeakers with a lot of efficiency. Accordingly, Thivan Labs currently offers three series models of speakers. Notable is the large model Anteros-9, an open baffle with two fifteen-inch for the low midrange and a large AMT for the high tone. The setup is complemented by two actively controlled low-frequency modules, each with a 21-inch driver. an open baffle with two fifteen-inch speakers for the low-mid range and a large AMT for the treble. The setup is complemented by two actively controlled low-frequency modules, each with a 21-inch driver. an open baffle with two fifteen-inch speakers for the low-mid range and a large AMT for the treble. The setup is complemented by two actively controlled low-frequency modules, each with a 21-inch driver.

There is also another open baffle model. More conventional, however, is the Eros 9, our test box. It is a bass reflex box with a classic PA equipment. This means: For the low midrange, we have a fifteen inch driver with paper cone, a powerful drive and, accordingly, efficiency. The manufacturer’s specification of 98 dB we can not quite confirm, but it is a good 95 decibels. For the high-frequency range one uses a 1.4-inch pressure chamber driver, to which a 90×90-degree horn is flanged. That’s an at least not very common combination; As a rule, broadly radiating horns with a much larger bundling in the vertical direction are found in the horizontal – here, the decision was made in favor of a more homogeneous radiation behavior. To anticipate the metrology comment: This works exceptionally well – the Eros-9 has a very homogeneous behavior in terms of sound radiation in the room. The woofer has a comfortably large volume, so that together with the downwardly reflecting reflex tube a very low tuning could be realized. Mind you: We still do not speak here of a linear reproduction up to the 20 Hertz, but of a hard-hanging PAPappe with a gigantic efficiency. so that together with the downwardly radiating reflex tube a very deep vote could be realized. Mind you: We still do not speak here of a linear reproduction up to the 20 Hertz, but of a hard-hanging PAPappe with a gigantic efficiency. so that together with the downwardly radiating reflex tube a very deep vote could be realized. Mind you: We still do not speak here of a linear reproduction up to the 20 Hertz, but of a hard-hanging PAPappe with a gigantic efficiency.

After all, the ground-level transition from reflex tube to the outside world ensures maximum low-frequency output. You can vary the height of the adjustable spikes here a bit. Speaking of spikes: The accessories supplied with the Eros-9 are exemplary in terms of circumference – including the covers with magnetic force for the recessed subwoofer. A note on our measurements: The Eros-9 is a speaker recommended for use with single-ended tube amplifiers. And as with many of these and similar speakers, there is no impedance linearization, that is, there is a distinct hump at the crossover frequency of the switch. This, in turn, means that the box on amplifiers with a low attenuation factor, like the aforementioned tube amplifiers, gets a bit louder in this area. It is well known to most of our readers that the LP editorial team also deals with loudspeaker development in the DIY sector. I have designed a loop of inductance consisting of a coil, a capacitor and a resistor, which, hung parallel to the input terminals, almost perfectly equalizes the impedance and phase characteristics of the box.

This should not be a criticism of the box and its developer – as I said, the bulk of such boxes is built without linearization – only an option for listeners with small power tube amplifiers. Our listening test then started with a slightly more potent combination that had just arrived fresh in our listening room: a set-up by Accuphase, in which I immediately ran into the inlet groove after putting the needle down to reduce the volume massively. My goodness, the Eros-9 have efficiency! After some experimentation, I decided to angle the speakers to the listening position – the high-pitch tuning can be fine-tuned by the direction of radiation, without discoloration creeping in. So the Eros-9 is an amazingly disciplined box for size and efficiency who are tonally no nakedness. Really amazing: A more neutral box of this size has almost never come my way. A certain amount of woodiness in the mid-range had disappeared after a while of re-importing – you should be aware that PA drivers in new condition and after a certain break game need their time to find their operating parameters. Incidentally, the sales department gives 500 hours (!) Of playing time for a brand-new box – that can get on in the face of occasional listeners. that PA drivers in new condition and after a certain break from play their time to find their operating parameters. Incidentally, the sales department gives 500 hours (!)

Well, the danger is, frankly, not at all: With the Eros-9 one does not remain an occasional listener, so much attracts the big box in its spell. It is the sheer inexhaustible reserves that make this transducer so fascinating. At normal levels and dynamic conditions, the Thivan box is simply a very good speaker. But then it goes to the point in the overall level, then you just feel the power of the huge membrane area, which then goes along every level jump fully, when all commercially available hi-fi boxes have long stretched the wings. And even at higher volumes, you also notice that the slightly falling to the high frequency range tuning, together with the fairly wide and uniform radiation characteristics of the tweeter, not even as dissecting precisely as most other horns,

Among them, the large woofer makes a more than decent job right into the mid-range – the low bass response is just the right thing in the living area: there is a dry bass that reaches well below 40 hertz due to the connection to the floor – for the boundless dynamics of electronic music just right.

Conclusion

At a competitive price of less than 4,000 euros, the Thivan Labs Eros-9 is a speaker that perfectly combines the qualities of a good hi-fi box with the dynamics of a PA speaker. Clear Buy recommendation!
