Anti‑MATTER

About the Anti-MATTER

The Anti-MATTER is a three-way, low-mass dipole loudspeaker built on the open-baffle principle: there is no cabinet to colour the sound or reflect energy back to the drivers. It suits rooms up to around 100 m² and is known for accurate timbre, transparency, impressive bass, refined treble and a very open soundstage.

At its heart is MATTER's own open-back ribbon tweeter. It has a larger radiating area and a wider frequency range than the ribbon Fanis Lagkadinos developed at Ypsilon, so it can work with first-order filters. The tweeter weighs about 2.4 kg and uses an impedance-matching transformer wound in-house. It is joined by an SB Acoustics Satori 6.5-inch midrange and two SB Acoustics 15-inch woofers made for open-baffle designs.

The crossover (300 Hz and 3 kHz) uses copper-foil capacitors, Duelund cast polypropylene capacitors and Jantzen MKTs, with coils and resistors made by hand at MATTER and no electrolytic capacitors. Midrange and tweeter levels can each be lowered from 0 to –2 dB, and the tweeter filter can be switched to second order, so the speaker can be matched to the room and the system.

The baffles come in natural oak veneer as standard or painted in any RAL colour; the frame is always black oak veneer infused with oil. On request, the Anti-MATTER b, a pair of dedicated open-baffle bass units, upgrades the system to the Anti-MATTER ultimate.
