Active loudspeakers, built in Ladenburg

High End.Two speakers. Two characters.

A loudspeaker is a decision about how sound enters a room. We make that decision twice, and we make it in opposite directions.

Both models are fully active. The crossover lives in the DSP, the amplifier sits in the cabinet, and every pair is measured before it ships.

Magrathea 7

Finesse, with a floor under it.

Rendering to follow

An Air Motion Transformer moves air by folding its membrane, not by piston stroke. The moving mass is a fraction of a dome, and you do not hear that as more treble — you hear it as less effort. Below it a ten inch midrange and a fifteen inch woofer in a vented cabinet.

  • AMT200P on the XMT200 waveguide, crossed at around 1.1 kHz
  • 10NTLS2000 midrange, 15NLW9500 woofer, crossed at around 300 Hz
  • 1080 × 560 × 480/400 mm, raked rear wall, White Nextel

Krikkit 8

Full throttle, at idle.

42.audio Krikkit 8 — horn loudspeaker, rendering to scale

A compression driver on a horn works at an efficiency no cone reaches. The result is not loudness, it is calm: at living room level this speaker is idling. Two fifteen inch woofers carry everything underneath, in a cabinet whose rear wall curves forward into the top.

  • ND3N compression driver on a 1.4 inch horn, crossed at 1.4 kHz
  • 2 × 15NTLW3500, around 230 litres, slot port tuned to 33 Hz
  • 1550 mm tall, curved rear wall, around 95 kg per cabinet

Active, without exception

No passive crossover in the signal path. Every way gets its own amplifier channel, the filters and the time alignment sit in the DSP, and we program the module before it goes into the cabinet.

Measured one by one

No pair leaves the workshop unmeasured. The measurement travels with the speaker, so you know what you own rather than what a brochure claims.

Built to be kept

Birch plywood, Nextel surface, magnetic fabric grilles and a milled copper 42. inlay. Serviceable, repairable, and designed to outlast the fashion it was built in.

Finished or self-built

Built.Or built by you.

Each model is available finished, painted and measured — and on request as a kit, with the Hypex module already programmed. The kit arrives raw. The Nextel finish stays with us.

Further series — a coaxial point source and a ribbon line source — are in development. What we are working on
