    I agree, not heard a single driver job I could live with for any length of time.

    I had a limited JVC boom box with what appeared to be 4 inch Fostex full range speakers and it came that way from new.
    It came out in 91 and I really tried to like the sound and with vocals it did sound good but had very little upper end detail and turning up the treble changed the over all tone to bright but still lacked any shimmer from cymbals.
    Since then I have heard very big Lowther horns and Fostex horns but they just don't move me like a nice 2 way speaker unless of coarse , a Super tweeter has been placed on top! But that changes the whole single driver thing in thee first place.

    I have to disagree. I've built Eikona based speakers with one, two and now four drivers per side and there is nothing wrong with the high frequency extension. OK, at 67 I might be classed as elderly (recent test shows I can still here up to 13KHz) but plenty of ears, some much younger than mine have heard and very much liked my Eikonas. As it happens I've also used decent multi driver speakers including Dynaudio Contours and Proac Response models but much prefer what the Eikonas do - no crossover and contrary to what a previous poster experienced, a very wide sweet spot. When I listen to a speaker with a tweeter now I am all too aware of treble separated from the rest of the music. Each to its own I suppose but I don't think it is fair to knock the Eikona for lack of treble extension.

    Ian, I am 67 later this year myself and a recent hearing test showed my hearing extends to 13.5k so age has not dulled it appreciably. When I built my Eikona 2 VTLs in early 2017 I was closely followed by 2 friends who took the same route, one with VTLs the other with the MLTLs, after we had all owned them for a similar length of time we all came to the same conclusion independently that there was something noticeably lacking in the treble, my friend with the MLTLs actually did a measured frequency sweep with a calibrated microphone which showed up several treble anomalies the most noticeable being a fairly wide dip of 8db centred on 7khz, this was confirmed on my own speakers by applying EQ/boost of that level at 7khz which went a long way towards giving a much more correct balance. As all 3 of us bought our Eikonas within a period of a couple of weeks we wondered if there was a quality control problem with a particular batch of drive units and informed Colin at EJ Jordan Designs who said he would FR test the Eikonas and report back, we’re still waiting, that was 9 months ago. Myself and one friend since sold ours on, the other loaned his to a friend and is now using a different pair of speakers.
    It was a great shame this problem was in evidence for all 3 of us particularly as we all enjoyed what the Jordans do well, image, dynamics and midband clarity in particular, for the high price of the drivers they should perform well in all areas not just some.

    To join in and correct a few misconceptions.

    To begin with, Ted was not a deaf and in fact had regular hearing tests as it was important to know what he was hearing. But by 84 no doubt his HF did roll off somewhat. As any good loudspeaker designer should be, he was well aware of this and always relied on his test instruments to tell him what was going on. He was also careful to audition his new designs with a range of people to cover both age and gender (in general, women have better hearing at HF than men). If you are male and over 60, you need to be aware of how hearing can change with increasing age and alter one's perception of sound (and not just at HF). The JX53 and JXR6 mid/treble units had, in any case, a treble response which easily surpassed 20kHz.

    Choice of loudspeakers and drivers is always a matter of personal taste. What to one person may seem smooth and unforced, to another may appear to be lacking in HF extension. Similarly, what seems clear and detailed to one may appear sharp and distorted to others. Here at EJ Jordan we aim for the most natural balance we can achieve. In that regard, we're following a similar approach to the BBC speaker design philosophy; the reference is always the live sound of acoustic instruments.

    We haven't tested the specific drivers that Steve-Z mentions having a problem with, but tests to drivers from the same production run didn't show up any problems. The Eikona 2 has been remarkably consistent and the number of faulty or below-spec drivers is in single figures since production began at the start of 2014.

    Regarding the extra components in Jon's loudspeakers, these are likely to be a baffle step compensation circuit. We're skeptical of the value of this - although many designers swear by them - and suggest that you try the speakers both with and without them. In our listening tests, we've found it preferable to have as few components between the speaker and amplifier as possible.

    +1. Too compromised. Life's too short for selecting hifi on theological grounds.

    (Same applies to the bullshit propagated - and worse, believed as gospel - about triodes vs pentode, single ended vs pp, feedback, op amps, NOS etc etc etc etc).

    For what it’s worth having a Zobel Network should not effect a speakers frequency response, it is there purely to make the impedance that the amplifier sees more even, particularly to flatten the rising impedance with rising frequency, as I mentioned earlier the majority of modern amps like my Cambridge CXA60 have a Zobel on the speaker outputs anyhow so adding one to the speakers is worthless.

    You were right about the frequency response as far as I could tell. However, there was a clear improvement in detail, transparency and soundstage when I removed the Zobel network, way too much to be any form of placebo effect. It's analogous to arguments about passive pres etc that if a music signal doesn't pass directly through some part of a circuit it can't have a negative effect.

    Thanks for all the advice guys. I took the baffle step compensation out and for a minute or two I thought wow. Then I realised I wasn't enjoying the music and switched it all off and watched a film. This morning I soldered the circuit back in and harmony has been restored.

    I have to say, at moderate volumes with a nice valve amp this is the best sound I've ever had. The sense of space and palpability surpasses anything I've had before. I can see how without a bit of correction people wouldn't get on with these if, like me, they are used to good 2+ way speakers. However if your priority is for a wide spread of music not chiefly rock and large orchestral oriented, then in big cabinets with some compensation, these drivers are amazing. Don't get me wrong, they do rock and orchestral well but you probably wouldn't own then just for that as you would probably want more scale. But they are good.all rounders with a major (massive!) strength on vocal, jazz, chamber music etc.

    Oh and there's no lack of treble from these drivers at all.
