One of the perennial hopes for audio designers is to combine the dynamic punch and extension of box speakers with the purity and clarity of box-less electrostatics inside the higher frequencies. Hybrid speakers with box woofer plus electrostatic mid-tweeter appear regularly and also have for decades. (About the most audiophile do-it-yourself projects with the Fifties was to assembled the Jantzen electrostatic tweeter with various box bottom ends; a number of the resulting speakers were exceptional for some time and would have their points even today). But with rare exceptions, those designs past and provides have not really jelled. Sooner or later the ear latches onto the discontinuity involving the box woofer and the electrostatic, also it stays latched on. Once heard, the discontinuity becomes increasingly annoying and that's no more that speaker. Like college boys inside the old song, hybrids come and go but mostly go.
The InnerSound Eros is an additional try. And by George, that one works! The Eros truly does solve the integration problem. To my ears, it is as coherent as speakers with two dynamic drivers, as well as more coherent than many of them. The result's a speaker with extraordinary virtues and few failings. It is smooth, sweet-sounding, clean, and pure, with superb stereo imaging performance. This is one hybrid that will not degrade its welcome.

Like a magic show, the Eros calls in the question: How's it done? Part from the response is only the extreme care and careful experimentation that the design involved. Roger Sanders, the designer, is a well-known expert on electrostatics. (He literally wrote the ebook on the subject he will be the author of a standard reference work about electrostatics). And he's been at the office on this design for some time. But there are two explicitly describable things inside the design that separate the Eros using their company, less successful hybrids. First the box woofer, which is a transmission line design, is quite clean, precise, and nonresonant. I'll be darned if I'll call a woofer fast since that is not what a woofer could be, however, if it weren't the wrong word, it might be the right word because of this one. Second, the crossover from box to electrostat is greater than usual, about 450 Hz, and contains steep slopes (24 dB/octave).

Traditionally, individuals have tried to run their electrostatic elements down to a minimum, to try to make as much of the sound electrostatic as you can. The trouble is that down at say 150 Hz, a dipole electrostatic element is interacting with the area way differently from the more or less omni box-woofer. This discontinuity of radiation pattern is nearly guaranteed to be audible. In the Eros, the crossover point is sufficient how the dipole's room interaction, and also its differentiation against room modes, is not because of this different (room modes are very closely spaced by 500 Hz). Also, the electrostatic element doesn't need to function to date down into the spot where dipole cancellation gets to be a major problem. So the woofer may be rolled off steeply, as it does not need to help you the electrostat over the crossover point. Anyway, those are my guesses as to the reasons it functions. But the true point is, it can.

In ways that if dipole operation is not so important above 500 Hz, then why make use of the electrostatic thing in any way? Why not merely use dynamic drivers on top too? The electrostat has other advantages, however. First of all, it's really low distortion. It is tough to obtain anything such as this clean a solid from a box mid/tweeter.

The 2nd point might be a more techno, nevertheless it counts for plenty. The electrostatic aspect in the Eros is forty inches high. This signifies that from say 1 kHz on up, the speaker is beamy in the vertical direction. There are no reflections up and running or ceiling inside the higher frequencies. And when it comes to that, because dipoles usually do not radiate sideways, you can get gone the first sidewall reflection too, should you set the speakers up right. The first reflected highs you hear arrive about a week after the direct sound. The result's the Eros sounds so clear you almost can't accept it.

I listened to begin course, but I couldn't resist a bit impulse response test. Result: pulse in, first arrival, then nothing inside the high frequencies for 15 milliseconds. Pretty amazing. No wonder the Eros sounds clear and also offers extraordinary insight into the acoustic environment from the recording. You aren't hearing your listening room for some time, rather than much of it then.

The Eros is really a biamplified system. But the cost includes a built-in amplifier for the woofer units, combined with necessary electronic crossover. You provide you with the amplifier for the electrostatic upper frequencies. The great thing about this arrangement is that not a great deal power is necessary from 500 Hz on up. (It really is bass that eats power). I wouldn't recommend a microwatt SET, however you will get big volume music from the medium power amplifier on top here. You do need a guitar amp though that does not mind the truth that the burden is capacitive, and as a result of 2? at 20 kHz. (Some amps should go in to a tizzy, and provide a rising, ringing top). If you must, you can even use another amplifier of your own for the bass the electronic crossover has outputs to the but I do not see why you need to.

The degree of the woofer can be adjusted so you can accommodate amplifiers of varied gains easily. You should avoid using the control like a bass level adjuster as such, however. There will be merely a narrow range of levels where the woofer and electrostat blend to give a built-in and uncolored midrange. Realize that level and leave the control there. (In order to boom your bass occasionally, obtain a tone control).

Just how does the Eros really sound? The bass is clean, precise, and reasonably extended. It won't go down to earthquake or 32' organ stop territory, there is however ample extension for orchestral music to possess its foundation. And the bass is very smooth and non-resonant. The midrange is also smooth, largely uncolored, and well-integrated. There is a touch height sensitivity from the interaction between your woofer as well as the electrostatic element, but at usual seating heights and usual distances, get up. In my room, when the bass level was set to create the smoothest transition from woofer to electrostat and also to supply the lowest coloration from the mids, the midbass and bass were slightly down in level. There is also a little relaxation within the presence region, so that the overall sound was slightly midrangy. (In the high treble, the amount comes home up some). This balance flatters lots of material (e.g., the human voice), and it also seems to be the kind of balance that recording engineers anticipate. Monitor flat (which is seldom delivered by monitors!) generally seems to make most material sound too aggressive. In but the, it really is tough to imagine anyone choosing the Eros balance certainly not attractive. And as noted, the sound posseses an almost magical clarity, and a clarity not at all purchased on the cost of exaggerated presence quite contrary when it comes to tonal balance. The speaker is just clear by nature, intrinsically clear.

Now we arrive at a unique feature of the Eros. It is not a problem exactly, In fact, I contemplate it an advantage. But you do need to find out about this. The thing is, the Eros speakers are beamy in the high frequencies, not only vertically while i already mentioned, but horizontally, too. When you sit back to listen, then you've got to be capable of see yourself reflected within the electrostatic diaphragms speakers pointed right at you or say so long for the high frequencies. This beaminess actually gives a kind of precision and solidity of stereo image you won't ever get if your speakers are flipping high frequencies all around the room. And it is possible to have fun with it a bit to have some of the time/intensity tradeoff stability from the Ohm 300s I discussed a couple of issues back. (Some but not the whole thing the Ohms are essentially unique there). But the beaminess might be distinctive from what you are accustomed to plus it usually takes just a little getting accustomed to it. The beaminess entails that just one listener will hear the perfect imaging and tonal balance, even though rolled-off highs off to the sides are not disagreeable. One could needless to say set up the Eros audiophile style inside the negative sense of pointing them lower the area with lots of backwall reflection, more sidewall reflection, blurry spacious soundstage, etc. But I wouldn't, and yo certainly won't get much first class if you do. This can be a subject which there seems to be some confusion. The truth is that stereo is predicated about the first arrival dominating the picture. Reflections, later arrivals, just blur the imaging and don't really contribute genuine stereo information, although one might in some manner take pleasure in the resulting spaciousness. The Eros is one of the best imaging speakers around, however it presents the purist picture, direct arrivals emphasized. It doesn't generate space each time a recording hasn't got any; it allows you to hear the phasiness of spaced microphone sound if the microphones are spaced, and so forth. What is there is exactly what you get.

Will, with one exception: Depending on the material, certain sounds can seem to be to come in the electrostatic panel itself a little more than really must happen. With images between your speakers and of course, theoretically that's the location where the images must be this doesn't happen. But when one hears those spacey recordings that fling images outside the speakers, the pictures can pop to the panels somewhat. It is tough responsible the speaker for that exactly, since such recordings are problematical of course. But is likely to auditioning, you might like to listen because of this with regards to whether the Eros making use of their theoretically almost perfect imaging present your preferred recordings you might say too distinctive from what you really are used to.
