The CORONA Ion tweeter – Lightening in a Bottle

A ball of massless, superheated air.

An 8mm sphere of plasma flame.

The very essence of Lightning.


With an untouchable bandwidth ranging 1.5kHz to 150kHz, it easily surpasses the most exotic tweeters in the world: Diamond, Beryllium, Titanium ... slow as snails by comparison.

The Corona is uniquely phase perfect, with zero ringing at any frequency, and pulse coherent for all 6.5 octaves of its operating range. No other tweeter system can lay claim to this level of performance.

Nothing except pure, live music can equal the complete transparency and naturalness of the Corona.

Matched with Lansche’s ultra-fast wideband midrange driver and their peerlessly executed active bass system, the No. 4.1 stands alone as the most revealing full-range loudspeaker in the world.
