"off duty" 1970 - 1997 - eine Werbezeitung für's US Militär

Die in diesem amerikanischen (Freizeit-) Shopping-Magazin angeprie- senen Produkte waren auschließlich amerikanischen und kanadischen Militärangehörigen ausserhalb der USA zugänglich - also zu kaufen - vor allem zu ganz ungewöhnlich (verblüffend) niedrigen US $ Military-Preisen. Zu der einführenden "off duty" Seite geht es hier lang.

Unsere 2. Lautsprecher-Marktübersicht nach November 1972

Mit dieser 1973er "market survey" wollen wir zeigen, wie weit diese Modell- oder Produkt-Vielfalt der Modelle und Firmen ausgeufert war und daß es sich selbst für einen Fachmann als schwierig herausstellte, noch irgend ein Produkt - im Vergleich zu anderen Produkten - bewerten zu können. Nach unseren Informationen sollen es zum Ende der 1970er Jahre über 800 Firmen in den USA gewesen sein, die Lautsprecherboxen angeboten hatten. Und nochmal zum Verständnis, wer nicht(s) bezahlt, war bei dieser Übersicht nicht dabei. Und wer seine Produkte sowieso nicht im Military Markt anbieten wollte, war auch nicht dabei. Die letzte Lautsprecher- Marktübersicht 1972 steht hier.

"Look and Listen - Till Your Ear's Content"

Here's one of the world's largest selections of loudspeakers
Off Duty / Europe / October 1973 -  By THOM PRINGLE

.

Welcome to the club.

PERHAPS YOU, like the majority of people who will read this SHOPPER, are doing so because you are thinking about buying a set of loudspeakers and are confused by all the theories and claims. Welcome to the club. Today, the amateur hi-fi enthusiast is almost as perplexed about loudspeakers as the experts, and manufacturers have made the whole thing even more confusing by splitting into two general camps.

Call the sides whatever you want - romantic and scientific, subjective and objective, poetic and practical - they're the same sides which always accompany an emerging science. Everyone agrees that loudspeakers can produce sound but how well they do that job is where the argument exists.

The romantics insist that no really meaningful parameters exist for loudspeakers and, therefore, subjective listening is the best way to choose a speaker system. The scientists, on the other hand, feel that human perception is unreliable and that measured parameters should be the major consideration. That strong arguments can be advanced for either side indicates there must be at least one undecided factor involved and, in the case of speaker systems, there are several.
.

Die "audiophiles " sind am Zug

Most audiophiles have discovered that their careful choice of a particular speaker system can be made instantly worthless by simply changing from one recording to another. In other words, the recordings themselves are one of the biggest variables in sound reproduction. Studio engineers are quick to point out that when they equalize, mix, edit and monitor recordings, they do so to obtain optimum results in the studio where the sound system (and placement) is usually a far cry from anything you might have in your home.

Der enttäuschende Kommentar zu den Spezifikationen

Another variable, which seems to be receiving only minor attention, is the measurement of speaker parameters. In the lucrative and fast-moving loudspeaker business, there has been little pressure to provide meaningful specifications and only a few firms have tried to do so. Therefore, there is virtually no standardization and making comparisons between different brands is next to impossible.

Recording techniques and measurement problems, however, are only two of the variables which allow two different opinions to both have some validity. Other factors include dispersion characteristics, room environment and personal hearing ability.

Sich auf die eigenen Ohren verlassen

Therefore, romantics point out, since there are so many variables and since so many speakers (the majority, in fact) do not present adequate technical information, you may as well rely totally on your ears and choose the speakers that sound best to you. You should, they argue, look upon the loudspeaker as something complete unto itself which is not necessarily an accurate scientific device. As in appreciating fine food, they contend, you don't have to know the ingredients to enjoy the meal.

The scientists, however, maintain that trying to choose a speaker system by audition is not only limiting but may be misleading. They say it is limiting because you are confined to the speakers available in one or two showrooms. It is misleading, they contend, because one's hearing is unreliable and the equipment and placement in speaker showrooms are not the same as in the home.

Auch auf diese "Tests" soll man sich nicht verlassen

Both sides are right but the two arguments must be combined in order to produce what we feel is the best philosophy when dealing with speaker systems. One can start by taking advantage of performance specifications whenever possible since they do provide at least some kind of reference. Then, the speakers can be auditioned and compared with competitive models. Beyond this, there's not a lot that can be done to make the selection process any more reliable - even test reports in hi-fi mags are difficult to use because you have to be a professional "between-the-lines" interpreter to figure out exactly what the testers think about a unit.

The procedure.

When you're finally ready to start hunting a new set of speakers, you'll need a program to follow so you can come as close as possible to finding the speakers you want. There are several ways to go about this, but in the next few paragraphs we've outlined a procedure which works well for most people.
First, figure out the size and general price range of speaker system you want. For the price range, consult your pocketbook; for the size, see our comments further on in this SHOPPER.

Next, consider the power requirements of the speakers. If you already have an amplifier or receiver, you'll need to match the power handling ability of your new speakers to your amp. If you're starting from scratch, remember that low-efficiency speaker systems require high-output amplifiers and that means more money!

Nur wenige Hersteller sagen etwas oder sind ehrlich

After this, read our comments on specifications and start digging into the speakers' performances.

Keep in mind that not all manufacturers give performance specifications and only a few give complete, referenced specs. You may not get far in this step but it will give you a good overall view of what's available.

The final step is to audition the speakers themselves. Don't rush this! Go to several speaker showrooms, if you can, and take your own records. Take records that you've listened to over and over, so you know every little scrape and squawk on them and be sure it's the type of music you like to listen to. If you enjoy symphonic recordings, don't take rock records.

Wenn Du lange genug recherchiert hast .....

Go to your friends' homes and listen to their speaker systems (yes, take your records along). Ask around to find people who may have systems you're interested in. (You'll find that audiophiles love to demonstrate their systems - even to complete strangers.) Keep a written record of the speakers you audition, their prices, model numbers and your impressions of them. After a month of looking and listening, you'll have a pretty good idea of what you want to buy.

Size.

In our listings we refer to all models as systems since all the units listed come with a matching enclosure or other ancillary equipment. Individual transducer elements in the systems may be referred to as speakers.

This year in our SHOPPER we have abandoned the traditional bookshelf and floor-standing terms in favor of three categories, small, medium-size and large. Most people choose medium-size units since they may be used in either small or large rooms, whereas small systems are usually limited to small areas and large systems are best used in large rooms.

Number of speakers and ranges.

Most speaker systems have some means of splitting the audio spectrum into two or more parts each of which is then fed to speaker elements especially designed to reproduce a particular range of frequencies. The result is lower distortion and better frequency response even though there is usually some loss of energy in the frequency dividing network.

Frequency response. (= völlig irrelevant)

There are three types of speaker manufacturers when it comes to frequency response; those who give no frequency response, those who give unreferenced frequency responses and those who give complete frequency response figures.

All of this is a reflection of the previously-discussed difference in philosophies. We, frankly, look forward to the day when a complete set of standardized, referenced specifications is available for all speaker systems. These would include a referenced frequency response at a given level in a standard acoustical environment with a stated amount of distortion. We have yet to understand what harm such specifications could do even if they are accepted by many as being worthless.

Frequency response statements which are unreferenced (do not give variance limits, such as ±4 dB) tell you, at best, what frequency range the speaker is supposed to cover. Very often, these types of speakers will lose over 20 dB of output by the time they reach their stated end frequencies.

Keep in mind, too, that the room where you place your speakers will have an effect on the apparent frequency response - this is where you may want to use the treble and bass controls on your amplifier and speakers.

Power rating.

There are two power ratings which should concern you. The first is the maximum power rating which tells the maximum amount of power you should allow to be put into the speaker system. In some cases, if you exceed this limit you may burn out the speaker units. In other cases, the manufacturer has found that driving the system above a certain limit seriously distorts the output of the system, therefore making any further increases useless. In any case, try to match the speaker rating to your amplifier so that you will have eliminated any risk.

The minimum power rating given by some speaker manufacturers means that you must be able to drive the speaker system with at least the given number of watts for satisfactory performance.

Impedance.

The impedance of the speaker system should match the output of your amplifier for best performance. Actually, the impedance of most speaker units varies considerably according to the frequency they are reproducing. This variance in impedance is reflected back to the amplifier which may reduce its output power by a considerable amount.

Components:

There may be as many as three types of components inside your speaker cabinet although sometimes functions are combined in two units or even one to save space and money. If you have three types of components in your system, you will most likely have a woofer to cover the low frequencies, a midrange unit to reproduce midrange frequencies, and a tweeter to take care of the high frequencies.
.

Der Bass

Most all woofers today are cone-type speakers designed to work especially with frequencies from 20 up to 500 or 1,000 Hz. The majority are direct radiator types with some of the big systems using horns to load the woofers for better efficiency. One exception to the cone-type woofer, is the Quad Electrostatic which uses an electrostatic membrane for low frequencies.
.

Mitteltöner und Hochtöner

Midrange units and tweeters use the same types of transducers; cones, domes, horns and electrostatics. Generally speaking, they all do an equally good job, since the job of creating high frequencies is considerably easier than that of pushing out the lows. One notable exception is the electrostatic transducer which is noted for its exceptionally smooth response in the treble regions.

In addition, you will run across many types of special units such as super-tweeters, upper-bass woofers, etc. This is carrying specialization to a high degree of development and here's a case where you may have to rely on your ears to determine whether it's worth the extra money. Some systems, too, will have separate outside terminals for each internal transducer thus allowing you to use bi-amp amplifier units.

Enclosures.

There are many different types of enclosures each with different advantages and drawbacks. High efficiency enclosures, usually big units or the less-expensive small ones, use

reflex arrangements whereby sound from the back of the speaker cone is circulated to the front to add more volume (also called ducted port enclosures) and horn enclosures. The horn-type enclosures have large horns attached to the front of the speaker units which effectively matches the speaker to the air in the room and provides excellent efficiency.

Low efficiency enclosures (including acoustic suspension types and electrostatic units) are almost always more expensive and require more power to operate. They are typified, though, by their fine frequency response and compactness.
.

Dispersion designs. (die Optik - das Aussehen)

The name of the game today among speaker manufacturers is dispersion. Almost all brands now have models which offer wide-angle or omnidirectional sound dispersion in an attempt to overcome an effect known as beaming.

In the average home hi-fi installation, speakers are placed in relatively small rooms and cannot always be in positions which offer the best acoustic or psycho-acoustic interaction. Thus, speakers designed as a box with a hole in the front often sound as if the sound is being "beamed" from them like a stream of water.

Wenn es doch nicht klingt

It's an unnatural sound which seems artificial and may become unpleasant by emphasizing the stereo or 4-channel separation that exists in a recording. In addition, the sound seems tight and restricted with little ambiance. To overcome this, many models have extra speaker units or openings on the sides or back of the cabinet to give increased ambiance by introducing reflected sound into the room. Some models use large amounts of reflected sound (80 per cent or more) while others use very little, depending on the design philosophy of the manufacturer.
.

Rundstrahler

Omnidirectional designs usually incorporate an upward or downward-oriented baffle against which the speaker elements fire to deliver a 360° dispersion pattern or they use a round-shaped enclosure which also gives an omnidirectional dispersion pattern.

The many different designs used by individual manufacturers to increase dispersion are too varied to cover in detail here. In the following listings, however, units with special dispersion designs are noted and you should try to include them when you start auditioning speaker systems.


There are hundreds of models in our SHOPPER this year - it's one of the largest offerings of loudspeakers in the world. You can look and listen till your ear's content.

Jetzt folgt die von uns künstlich geschrumpte Auflistung

Da viele der Spezifikationen nur noch die Seiten füllen, haben wir die ganzen "Specs" weg- gelassen, da sie sowieso keine reale echte bzw. glaubwürdige Aussagekraft haben. Der Frequenzgang zum Beispiel ist völlig irrelevant, wenn zum Beispiel in einem 20m² Raum Frequenzen unter 40 Hz überhaupt nicht gehört werden können.
