The Harbeth phenomenon


In my search for a new pair of speakers, I've gone through many threads here and noticed that many owners or fans of Harbeth have almost a love-like connection with Harbeth speakers. It is almost as if the speakers cast a spell upon them. I know many audiophiles love their speakers but Harbeth owners seem especially enamored with theirs. I am extremely puzzled by this phenomenon because on paper Harbeth speakers look average at best and lack many of the attributes that generally make a great speaker.

Their sensitivity of generally around the 86dB mark makes them rather inefficient and therefore, at least in theory, not a good match for many lower powered tube amps, or any amps below 100wpc. Their frequency range is simply inferior to most high-end speakers since they don't go below 40 Hz. This alone should, again at least in theory, disqualify Harbeth speakers from consideration as top high end speakers. And yet I've never heard anyone complain about their bass, while people complain about lack of bass in the Gibbon Nines from DeVore, which is a fantastic speaker. Their cabinets look like a cheap DIY enclosure (disclaimer: I've never seen a Harbeth up close, only pictures). The 7ES-3 is rated B-Restricted, while the smaller and cheaper Usher Be-718 A-Restricted in Stereophile but garners nowhere near the same amount of admiration, praise and following among audiophiles.

So what's going on here? Is this a big conspiracy plot by the company that paid off a few hundred of people to infiltrate audiophile internet forums and a few reviewers? I am of course joking here, but the question is serious. How can speakers so average on paper be so good in real life? I know the opposite is often true, but you rarely see this phenomenon.

Please speak up.

Harbeth has a musicality about them that is hard to pinpoint - it is the sum of good engineering and know-how, coupled with a critical ear for musicality by the designer. The mid-bass units (radial drivers) are propriety and are based on internal r&d. Part of their magic lies here. In addition, they are designed to get human voicing correct and, are outstanding monitor speakers (who have a somewhat restricted LF).

Although the cabinets look retro and dated (which I like), I never thought they were cheap. Again, there is a design philosophy behind them.

Admittedly, Harbeth loudspeakers are not perfect nor everyones' cup to tea (from the sonics to the looks). But they get most things remarkably right when it comes to musical enjoyment and have a loyal fan base. Plus, they are reasonably priced when one compares to what else is out there in the sub -5k range (excluding the M40s).

my 2c worth based of my experience with my M30's.
Onhwy61, check my threads and posts on A-gon and it will become obvious I'm not a "plant." Unless you were being facetious.

Dobieguy, no I haven't heard any of the Harbeth speakers but I'd love to. Please note that I did not start the thread as a skeptic or trying to disparage Harbeth or question their following. I was genuinely curious what made these speakers stand above the competition and cause so many audiophiles to be so in love with them without all the top specs that speakers ranked so highly typically display on paper. Through so many interesting responses, I think I'm beginning to understand what it is.
Mmike84's comments mimic my feelings on the subject.

Most of my time as an audiophile has been spent with Dynaudio speakers,
including the C2's & C4's, both of which are exceptional. However, I found
myself tiring of having to crank up the volume to get the Dyn's to sound their
best.

So, I sold my C4's for the less expensive Harbeth M-40.1's on a whim, as I had
never seen or heard them. I've found the Harbeth's to be more musical (albeit
less exciting than the C4's)... and to me, the 40.1's are more satisfying & sound
great at low to moderate volume levels. Great bass, midrange and fatigue free
highs... and the flat impedance curve makes them easy to drive with a 75 WPC
tube amp.

YMMV, as it all comes down to personal taste.
Musical. How do you measure musical?

Speakers that measure flat and neutral do not sound musical, people are not attached to them. Speakers with personality like Harbeth and Sonus Faber leave people mesmorized even though they are far from neutral.

Wilson, YG Acoustic, and others go to great length to minimize cabinets vibration because cabinets should not have a sound. And Harbeth's cabinets do what?

Magical midrange, I know lots of speakers that do magical midrange and still relatively neutral. You can have your cake and eat it too.
Its hard to go wrong with harbeths. They do so many things right than most speakers.
