Anatomy of a loudspeaker

By Philip Wong

While we are miles ahead of our early entertainment punters both in high-definition audio and video, little has evolved over the years when it comes to the fundamental of audio reproduction. The basic design of most mainstream loudspeakers is still revolving around speaker drivers, the cabinet and its electronics--yes, there's a circuit board hidden inside your boom box. To help you wade through the various jargon and elements of this important home theater component, here's our quick guide to the anatomy of a conventional loudspeaker.

Our subject in this article is the Bowers & Wilkins (B&W) DM604 speaker illustrated on the right. It's a three-way front-ported floorstander equipped with a 25mm dome tweeter, a 180mm midrange driver and another two 180mm bass units. Already overwhelmed by the technicalities? Fear not, read on for more details.

One who wishes to purchase a set of threatre sound speakers should remember that the sound that you hear in the showroom or any of the hi-fi outlets would be different as compared wth placing them in your hall.

This is due to many factors such as the accoustic and insulation placed in the showroom, proper hi-fi cables instead of the normal black and red electrical wires, shape of the hall, the amp of the amplifer and most importantly, the components of the speakers.

I bought my speaker system from a specialist audio hi-fi shop at The Adelphi. Before I decided on the size and type of speakers and as I have a big hall, the hi-fi specialist came to my house, studied the area and configuration of the hall. He then came up with several appropriate combination systems including the monster speaker cables for me to select. The cost also differs from one to another.

At the end of the day, I spent a substantial sum of money on the speakers and the amplifier but no regret.

The above is only for those who have great passion and appreciation on the clarity and details of the sound quality delivered from the speakers.

If one is serious of wanting a proper set, it's best to go to a specialist hi-fi shop and ask them to visit your house and come up with the appropriate recommendations.

whatever the technical specs says about a speaker system, nothing beats your judgement of hearing when you demo the unit. though Wharfedale is now a chinese company, they still adhere to strict quality standards to produce good sounding speakers, and continually challenging at the top echelons of the AV world. comparing the similarly spec'd B&W DM (in terms of size/power/price..) series with a Wharfedale Pacific-Evolution, I've found that the pacific evo gives better response, a real value for money.

No doubt today's speakers improved some but I see decline of fine hi-fi stores. Most chains sell just mediocre systems and many fine brands disappeared into magazines. I'm sure the main reason is cost. 5-7 channel system cost more than 2 channel stereo and since the finest brand's prices skyrocketed, who can afford a great system.
One way around it is a fact, that five small speakers can be as loud as 2 stereo.
