Furthermore,
use a tweeter in a box without cross over, and it dies within seconds! Meaning:
Power handling is related to the complete box system playing standard music
and not to the tweeter.
Our tweeters have been used in well-built speakers capable of handling several
hundred watts! (of standard music!).
As a guidance, simply use the tweeter with care and use your brains. Make sure
not to expose the unit to defective power amplifiers or to use it with too
small amplifiers (clipping).
Use this general rule: If your normal well functioning ears can handle the
sound pressure without being stressed, then the tweeter can too! It's made for
human beings.
Use it properly, with a proper crossover, and at least keep direct signals
below approximately 2 kHz off the tweeter. Then it will handle all reasonable
powers used in a normal domestic living room listened to by normal reasonable
persons with normal well functioning ears. Got the picture?
And still, compared to the majority of other 3/4" (19-20 mm) dome tweeters,
the power handling is eminent thanks to the very high mechanical finish.
Reliability and production quality:
All
these features would be of no value if they were not heard. Therefore, try it
for your-self, and be convinced!
Our other customers are convinced. They also benefit from the fact, that the
production quality is extremely high. Production procedures are developed
during many years, with the special goal to achieve maximum control on
uniformity and low distortion.
This is best understood by telling you, that during the last 15 years we have
shipped well over 100.000 units, and only a few handful of those have been
recognized as defective as a result of our mistakes.
Used in high quality loudspeakers all over the world and under very different circumstances,
we have only received less than 100 units in return with faults.
This is less than 1 out of 1000!
We believe this to be a good measure of quality!
Furthermore: Out of these few units returned, several were obviously
damaged by the customer them-selves, by overloading from clipping amplifiers
and other misuse. The failure rate from faults that can be related to our
production therefore is far below 1 out of 1000. We believe that's pretty good!
Final quality control tests:
All
units leaving HIQUPHON are tested at least tree times, two of which are
listening tests through-out the entire frequency area.
As a special test of the mechanical assembling, we test the unit through a
completely crazy dividing network, giving the unit an awful bad time in the
area 100 Hz to 3000 Hz to make sure, that there is no rattling or other
mechanical noise at all. (This frequency area is the area in which the
resonance's are most likely to generate undesirable mechanical noise if any
mistakes have occurred and consequently will generate higher-order
unequal-numbered harmonic distortion).
The production quality is very uniform, and many customers have asked if the
units were specially selected or matched. But no! That's just the way we do it.
Precision and commitment combined with the many years of learning and
listening.
Yet of course, small differences will occur. Therefore we can offer to supply
with every single unit a certificate curve-data sheet for your own further
pair-matching, or we can supply the units as matched pairs if necessary (Our
OW-series). An additional price will be calculated for that kind of service.
All units in our OW-series are born as matched pairs, and therefore matching
and data sheets are part of their prices.
Custom-made tailored variants:
We
can supply different custom made subversions against extra payment. Some of
these are mentioned below.
The Gold/Platinum option is a good example of special options. The OW3 (gold
dome) and OW4 (platinum dome).
All-over flange diameter:
We
can supply the unit with diameter between ø92 to ø94 mm, as it is possible to
machine the flange.
We recommend that you use the standard ø94mm, but if you want for instance
ø92mm diameter flange, you can have it.
Different number of assembling holes in
front:
Normal
standard version is supplied with 3 holes for countersunk screws of size M4.
We can supply the unit with 6 assembling holes, if so needed.
