  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

Which speakers are the brightest?

    There was a research letter in The Lancet in the late 90s that showed that some persons can hear all the way up to 26kHz. I sent John Atkinson of Stereophile a copy. I wonder if I can dig that up somewhere? Anyway, oil-can resonance for aluminium tweeters is usually around 20 - 25KHz so maybe that's why some people find these tweeters objectionable? Dunno.

    I find brightness volume dependant, at the sort of levels I listen at then nothing is terribly bright.

    I once owned some Neats that I thought sounded wonderful, when I sold them I delivered them to the new owner who promptly hooked them up to an awful Krell thingy and cranked up some metal, they were painful to say the least.

    Joe Hutch Can you hear Talvin Singh?

    A lot depends on the room. I imagine many speakers that sound over-bright in a sparsely furnished room would sound fine in a more heavily furnished one. Similarly a speaker that sounds fine in the former might sound dull in the latter.

    This paper has been debunked. The speaker used in the experiment may have been producing noise in the audible range.

    I can understand how some systems can come over as bright, but can often measure quite well. I was recently in a bar with a live band with quite a lot of HF energy (cymbals etc) and it made me realise just how hard that probably is to replay in a living room.

    From my experience, rooms play havoc with speakers' frequency response and an issue with the top end is very often a manifestation of a problems a lot lower down in the frequency range.

    Yes, I think that is true and related to the way different frequency ranges are propagated within a room.

    Zu speakers can come over as pretty 'fierce' in the top end - if that helps the OP.

    Not the old Dr Oohashi paper again. Not only has it been thoroughly debunked a number of times, but in the 17 years since it was published there hasn't been any independent replication of confirmation of the result.

    I'm like you on this....I played the Alan Parsons HiFi setup recordings (which I recommend) and it has sweeps and tones all the way from 20Hz to 20Khz and I can't hear anything above 14Khz although it feels like something is there when I approach the tweeters. I only feel rumble below 40Hz.

    I once blew (actually several times) my tweeters in Linn Kans and replaced these with Hiquaphone IIs, thought it would be an upgrade but they sounded a bit too bright for my liking....maybe the B110s were too old and not keeping up with the new tweeters. I wished I had bought the cheaper ones Oskar recommended the dpl-1s (I maybe wrong here, just typing from memory over 5 years ago). Edit: I'm 53.

    It could be that what you hear when you are close to the tweeter is actually intermodulation products that reflect below 14 kHz.

    Rodney gold Im just me...

    Room , treatments, distance , furnishings all affect brightness perception (2-5khz range) as does the level you play at (fletcher munson)
    Worst speakers I ever had re harshness were Modern Klipsches RF83 ... that horn had me reaching for earmuffs
    Even if your hearing only goes to , lets say , 12k ..if you low pass a set of speakers , even with a 48db/octave filter above that , the sound loses air and some detail/sparkle..

    I find some Klipsch speakers really bright ..

    They are voiced to sit on the floor and near a wall. Put that piezo tweeter at ear level and lose the corner gain and of course they are then bright

    Maybe Klipsch speakers are tested with a room full of people. It's a bit like setting up the pa when I was in a band.

    Before the people come in it sounds bright and lively. With the audience in place it sounds much less so.

    Yesterday I heard some budget Dali speakers in Mr Richers shop. Driven by some midi system thingy they sounded a little thin but the the upper part of the f spectrum was interesting to hear, nicely detailed.

    I'm now forever wondering what they'd sound like with a bit more muscle driving them, like my Supernait 2. Or is that a a silly idea?

    My next step: I'll try a f based hearing test!

    What piezo tweeter? Klipsch used the EV T35 horn tweeter for decades, then at some point replaced them with a lower cost dynamic equivalent (I dunno if The T35 became unavailable, or just became too expensive...).

    The K77 (EV T35 variant) is still used in all the Heritage line and is a proper horn tweeter. It is not a bad tweeter IMO, though not that extended (usually out of the game around 18kHz). Much of the problem is people not understanding where a Heresy should be placed - it is designed to sit flat on the floor and either against a rear wall or in a corner, as such it's tweeter is set at the crossover higher than the mid, which is higher than the bass. The balance is decent enough when used as intended, though beng very efficient they will show up any grain or hash in non-class A solid state. Far better with tube amps of their era.

    Celestion SL6s had metal domed tweeters & were hardly bright, My current German-made Quadrals have ribbon tweeters that supposedly extend into Exahertz region that are detailed without being bright (unless the music is).
    I maintain it's not the tech or the country of origin but the implementation.
