Our two-way speaker systems ADS L400, L500 and L700 were developed right along with our more expensive studio speakers for the best possible reason: we wanted to create a coherent line of loudspeakers where every model, regardless of price, would have to reproduce musical sound with an optimum of clarity and a total absence of coloration.
When our engineers finally were able to meet these criteria, we called this remarkably open quality the 'Invisible Sound' of ADS. Since its introduction only two years ago, it has become the standard of excellence for many professionals and dedicated audiophiles.
Our lowest priced speaker, the ADS L400, costs less than $100. Yet it shares with all other ADS systems the 'Invisible Sound' and the technical refinements that make this faithful response to the input signal possible. For instance, we install only one type of soft-dome tweeter, a masterpiece ADS L700 in sophisticated audio design. Also, all ADS speakers utilize similar small-diameter woofers and the same computer-grade materials for the crossover networks. The craftsmanship and materials that go into every cabinet are of uniform, high quality.
Of course, yon buy a speaker for its sound.
When you listen to one of ours for the first time, please note how the virtually massless tweeter meticulously renders every treble detail. Discover how smoothly the woofers take over the midrange frequencies; feel the strength and precision of their compliance to a sudden bass signal.
As a total value, we believe the ADS L400, L500, and L700 are without competition in their respective categories. Your local ADS dealer will proudly prove this claim in his sound studio.
- Take the time to test our speakers critically. Take the step beyond transparency. Experience 'In visible Sound: It will then be impossible for you to accept anything less.
