Lansche Audio No.7 Loudspeaker

Smitten!

I should emphasize that the overall tonal balance isn’t thin, lightweight, or threadbare. Rather, the No.7 simply lacks heft and oomph, particularly when the music is big and dynamic.

Lansche has not only made wise tradeoffs in this design, but has also executed those tradeoffs masterfully to produce a remarkably engaging and involving overall sound. The glorious midrange and treble could have easily been rendered irrelevant by a presentation in which the bass sounded like a detached weight lagging behind the music—a constant reminder that the listener is hearing a loudspeaker. It’s a testament to this design that the whole thing works so well. I was never aware that the No.7 features a radical mixture of technologies—I simply enjoyed music immensely through them. The No.7’s presentation is powerfully compelling, and exquisitely beautiful in a way that most loudspeakers are not.

An experienced listener who visited used an interesting word to describe the No.7’s overall character: “feminine.” It fit perfectly: lithe rather than muscular, emotional rather than visceral, affable rather than assertive—and delightfully charming.

Conclusion

With its massless corona-plasma tweeter, the Lansche No.7 ventures into rarely charted territory. This driver has many compelling virtues including world-class transparency, airiness, lack of hardness and grain, and the ability to make instruments and voices sound eerily lifelike. It simply sounds unlike other loudspeakers, bringing music to life in a way that’s wonderfully enjoyable.

The tweeter is not only at the speaker’s physical center; the entire design flows from this transducer’s dictates. That means coupling the massless tweeter to small and lightweight cone midranges to avoid an audible discontinuity. The woofers, in turn, must then be matched and tuned to the midranges. The result is a loudspeaker that forsakes weight, power, slam, and big dynamic contrasts for a seamless and coherent overall sound that doesn’t detract from the tweeter’s magic. It’s not just a wise tradeoff, but one that’s been beautifully executed. The No.7, remarkably, sounds “of-a-piece.” But it’s not a loudspeaker that will satisfy all tastes.

Nonetheless, I can’t imagine anyone sitting down in front of the No.7 and not being as captivated and charmed by its unique allure as I was.
