Default Who makes the lowest distortion speaker drivers

Simply put, drivers are the most distorted stuff in the whole long chain. And this makes me having nightmare.

Any way you look at it, a driver running at low power will have less distortion than a driver running at high power.

While keeping an eye on other compromises (cone break-up, cabinet size etc), larger more efficient speakers will have less distortion than, say, a 4" driver moving 10mm p/p absorbing 100w+.

That said, high-efficiency PA speakers have a wide range of performance. I'd take a low-efficiency 7" midbass with lots of copper in the motor and a really nice cone/suspension over a high-efficiency cheap 10" PA driver. An expensive PA driver will likely have less distortion than either for a given power input.

Most people are talking about harmonic distortion when discussing driver distortion. In my opinion, and what I've read from some industry pros is that harmonic distortion in a decent modern driver operating within their intended range does not correlate to user preference.

IMD may play a huge role in listener preference but there is no standard for measurement and can have infinite combinations.

Klippel measurements are a step forward in characterizing other non-linear driver issues but it's hard to interpret as an uneven BL curve doesn't mean it's not linear as most assume.

Then there is time domain distortion....

My point is it is way more complicated then a simple hd sweep...

I like the engineering and ideas that go into SB flagship drivers....

I'd chase excellent power response over ultra low distortion any day!

Of course it is. That said, a driver operating at low power will always produce less distortion than a similar driver operating at high power.


Lets get specific, though - what's your nightmare?

Hi Chris,

I've looked over a bunch of HD sweeps and I do not see a correlation between sensitivity and distortion all else equal.... Maybe this is generally accepted and unknown to me? I can agree in at high SPL where the motors are getting hot and compression kicks in. Otherwise do you have a source or evidence of what you are saying? Just would like to know for my own learning

In my mind, the distortion effects I care about most:

1. Compression
2. Stored energy / resonances that keep the driver in motion after the signal has stopped
3. Doppler from the woofer's reactive energy moving the baffle in the Z axis.
4. Intermodulation distortion between drivers - Woofer to Tweeter caused by the pressure wave of the woofer moving over the tweeter.
5. Harmonic distortion.

Did I miss anything? Now can you sleep?

Best,



Erik

Tell us what your nightmare is. Everyone lives with the same distortion as you.

Linkwitz did some driver testing that may interest you:
