It is probably fair to say that there has been a fascination with loudspeakers right from the very start. Not so much with the technology behind them, but simply due to the fact that they can reproduce sounds of familiar things without being the thing themselves. For example, a loudspeaker may reproduce the sound of breaking glass, without being made of glass or shattering in the process. It may reproduce the clanging of hard metal, without being made of metal or clanging against anything itself. And, most importantly, it can mimic the sound of voices and instruments, a discipline in which human ears are especially sensitive and therefore critical. Even on people with emerging hearing disabilities, the voice level frequencies are usually among the last to go.

While attempting to sound natural and accurate in their reproduction of music, most types of loudspeaker are first and foremost entertainment devices, and as such, they need to be able to survive on the entertainment market. As our understanding of this market and our behaviour as consumers changes, so do the design choices made by the manufacturers. Loudspeakers today look rather different from those made in the seventies. While modern designs tend to be tall, slender and cool looking, their older cousins were often wider and stubbier with warm looking wood finishes. However, these are just the visible features and would be alright, if it was not for another trend, namely that of the infamous target group analysis.

Let’s face it. Well-engineered speakers, and the electronics needed around them, are by no means cheap. Manufacturers are therefore facing a rather mature customer group that has the space, time, and available income to purchase up-market loudspeakers. If income tends to improve with age, sadly our hearing often does not. It could well be argued that the two curves are diametrically opposed. Hearing loss affects both our ability to discern high notes, as well as our sensitivity to low volumes. Consequently, in A/B comparisons, the speaker with the loudest high notes will, more often than not, get to enjoy the ride home. Sadly, this type of speaker will have a life-long imbalance when it comes to natural representation, an obvious weakness that all future owners will have to come to terms with.

Many things can and will go wrong at the point of sale. The speaker that sounded great in the shop, might not sound so great when placed into our own living space and hooked up to our system. The room, the furniture in it, and the electric synergy with our existing components will all affect the impression of sound. If possible, loudspeakers should therefore be tested and compared at home. Some dealers will be supportive and make such testing possible, however, there is a natural limit to this, and we might feel pressured to make a choice. The other option is buying loudspeakers used. Provided that the speakers are not broken on purchase, they will either sound great or can be sold again, usually for a similar or even higher price.
