Music-lovers who derive pleasure from listening to music at home know that the loudspeaker plays an extremely important part in determining the naturalness and refinement of the musical result.Its performance can make or mar one’s satisfaction in what is heard: it can sound truly musical and convincing or it can merely sound like a loudspeaker.
The aim must be to introduce the least possible distortion, maintain a uniform frequency response and provide adequate efficiency in a device which has the complex task of converting electrical energy into mechanical form, and hence transferring this to the surrounding air as acoustic energy. Low-frequency notes must sound natural, not emphasized (though this depends partly on the room). High-frequency notes must reproduce cleanly, adding lustre to the sound. Most important of all is the mid-range, where the ear is most sensitive and where ‘hi-fi’ – as distinct from music reproduction – can be so tiresome.
These, then, are some of the factors, which must be held in suitable overall balance. Clearly, the drive unit in a loudspeaker system will bear a large share of the burden. The units employed in Lockwood loudspeakers are among the finest available: they are noted for their superior characteristics and performance capabilities.
But perfect liaison between drive unit and enclosure is vital. Put simply, the enclosure’s responsibility is to avoid cancellation of low frequencies; in fact, to ensure that this work is well done entails great skill in determining cabinet proportions, details of construction and theapplication of acoustic treatments. Craftsmanship represents a valuable part of what Lockwood have to offer the music-lover. Experience of design is no less important.
