loudspeakers

[steve]

I have a query about two loudspeakers acquired from different
companies.

One speaker is larger and sounds better (softer) than the other
speaker.

The newer smaller speaker produces a very clear but harsh sound.

So how would one try to fix the smaller speaker, to produce the softer
sounds.

Harsher and softer are hard terms to quantify.

Does the small speaker look defective?
If you are talking about cutting some of the hi frequencies from the small
speaker you can do that electronically.

Subjective opinion.

You don't. You buy 2 speakers of the same type you like.

I suspect that the difference in perceived sound is due to frequency
response or possibly an unwanted resonance. You could drive each speaker
separately with an audio oscillator over a range of frequencies (and
volumes), and either detect harsh sounds by ear, or even better, use a good
microphone and a scope (or distortion analyzer). Once you determine what is
actually causing the "harsh" sound, you might be able to do something
mechanical to the speaker enclosure to reduce resonance, or use a filter
(or compensation network) to produce a more pleasing sound.

As others have said, much of this is subjective.

If you want to try Paul's suggestion, you can

download my Daqarta app. It uses your sound card
to generate test signals, and to analyze the mic
response. You can read about how to use it for
frequency response and distortion measurements
here (copied from the Daqarta Help system):

http://www.daqarta.com/dw_0a00.htm

You can probably do everything you need within the
30-session/30-day trial period. After that you
won't be able to analyze input signals unless you
but the program for $US29, but the signal
generator is free to use forever whether you buy
or not. You can still use that to listen for
resonances or "bad" frequencies, for example.
