Lansche No.3.1 (( Worlds Best Tweeter ))

The Lansche No.3.1 is one of the finest and most musical
speakers ever made, using the same mid-range driver and tweeter
as Lansche’s flagship No.8.2 speakers, which retail for near $300,000. And the
same woofer as Lansche’s No.7 speakers, which retail for over $100,000.

The book matched high gloss ebony finish is absolutely stunning and this wood
has become hard to find and expensive, therefore Lansche doesn’t offer this
finish anymore.

This speaker has been advanced to an entirely new level by adding a set of
pure silver wound transformers, made by Ypsilon Electronics, to the
Plasma tweeters. These silver transformers are mounted inside the speakers,
behind the tweeters. The improvement in sound is absolutely stunning, bringing
this speaker to an entirely new level of outstanding performance.

In addition all the internal fuses have been upgraded to HiFi Tuning Supreme, total 6 for the pair. The main fuse for power to the tweeter, and the fuses in the tweeter crossover board. This was another fine improvement to the sound.

The No.3.1 speakers are ideal for both small and medium
sized rooms. They can even work well is rather large sized rooms and perform
amazing. The condition of these speakers is excellent and they are just
beautiful to look at. They will ship in their original cartons, plastic wrapped
and strapped to a strong pallet for safe delivery.

THE LOUDSPEAKER

The No. 3.1 loudspeaker is a perfect introduction to
the fascinating sound world offered by a plasma tweeter. The goal of
this design was to create a benchmark two-way loudspeaker with compact
dimensions and an elegant appearance that is easy to integrate into any
living or listening space. The main challenge was to develop a driver
for the midrange and bass frequencies that is seamlessly matched to the
superior speed and resolution of the plasma tweeter. This 20-cm driver
design combines a very fast midrange response with a beautifully low
bottom end and is complemented by a 22cm long excursion, which is
integrated in a down-firing arrangement.

DESIGN

The enclosure is based on a combination of
MDF, low-vibration ceramics, and absorbent heavy foam. On the interior, a
reinforcement matrix provides interlocking boards to further increase
the enclosure's rigidity. The base plate is a one-centimeter-thick
aluminum slab that also holds the floor spikes. The loudspeaker cabinet
is thus completely decoupled from the floor. The angled inclination of
the narrow baffle is an effective solution for time-correcting the
impulse responses from the two transducer systems. The loudspeaker's
phase position is perfect at a seated listening height. The No. 3.1
model thus satisfies both your needs for exquisite sound quality and for
appealing, subtle visual aesthetics.
