Explain to me Hz - kHz for speakers

First, most adult humans cannot hear above 16-18kHz, so all of the ones listed have more than adequate high frequencies.
Second, the middle one seems to have more bass extension than the others but....
Third, none of these specify a tolerance for those ranges. No speaker is flat and for a range, such as those, to have any useful meaning, it must be qualified as being within a range of limits. For example, speaker 2 could be 55Hz - 50kHz (+/-10dB) while speaker 3 could be 60Hz - 20kHz (+/- 6dB). In that case, #3 is probably better.
Fourth, none of such specs is very useful in isolation from all the others, most of which are not given.
Fifth (and last), the most important parameter for a center channel is that it match the left and right speakers in timbre. This is usually accomplished by choosing one from the same line or, better, an identical one.

Assuming all three are using a standard +/- 3 dB tolerance, the 55 to 50kHz speaker has the "best" spec.

But, there are a myriad of other issues ... such as:

1. How accurate those specs are compared to measured results
2. How the measure off axis
3. Their relative efficiencies
4. How do they sound to you ?

In other words, specs don't mean a lot.

That spec is not really meaningful in any way in terms of telling you much at all about how a speaker sounds, not to mention they give absolutely no +/1, so each of those could sound abjectly horrible anyway, and the lower number could be -10db or it could be -3db, we don't know.

It's kind of like choosing which car to buy based on what tires it has on it. Not really that relevant.

It all comes down to how big the speaker is. If it's a bookshelf or center channel and it falls on you, it's a hertz. If it's a huge tower and it falls on you and kills you, it's a kilaherz...

Is it true to say that the frequency response is the best judgement of where the crossover should be set?

Bad assumption since any speaker that does not specify a tolerance is unlikely to have such a good one.


Agreed and, especially, the ones quote.

Yes, if the number is trustworthy and there are no complicating circumstances relating to acoustics.

Was I the only one to laugh at that?

What is means is that the specs are meaningless but it may not reflect anything about the speakers.

That just came to mind, im ready to upgrade my speakers and ive been shopping for some sattelites (room and space issues) from Polk, Klipsch, and Infinity and I noticed most of the time the frequency responce drops around 100hz. With the crossover set to 100hz wouldnt that send some midrange or unwanted signals to the subwoofer?

EX. Klipsch Quintet 2 speakers (100hz - 20khz) and the ED A2-300 (the A2-300 range is 100hz-18hz I believe

100Hz is not mid-range; it is definitely upper bass. My concern with such a crossover to the sub is its potential audibility.

It's a good thing I was not eating while reading this ... TOO funny ...

OH MY GOD!

CRAIGSUB THINKS I'M FUNNY!

THE UNIVERSE HAS ALIGNED, MY TAXES WENT DOWN, MY SKIN CLEARED UP,
AND THERE'S PEACE IN THE WORLD......


Now please send me those leftover subs your not using...

ROFLMAO!

OK what do all these acronyms mean???
ROFLMAO

I see this stuff all the time and I can only figure out a tiny few of them!

Rolling On the Floor, Laughing My A$$ Off. You can google any of these.

I could have said LOL (laughing out loud) but I got a bigger chuckle than that. Most times the threads and posts in these forums are so serious, and they probably should be, that I find humorous comments quite refreshing.
