The Celata 88 was motivated by our frustration with existing HiFi speakers—their high mark-ups, dull sound, and mostly terrible looks. The design goals for the Celata 88 were dynamic, engaging, emotional sound from a gorgeous speaker that could complement anyone’s most loved spaces. We had no idea what the final design might look like, but it had to have a very high spouse acceptance factor. It had to be compact, a stand mount, and with a huge sound that competed with floor standers. And it had to look timeless.

Ultimately, the form was dictated by function. The only non-functional structural features of the Celata 88 are the two chamfers on the top edges—they just look better than sharp corners. Even so, the cabinet design is reminiscent of Onken speakers, a Japanese design from the 1960s and 70s, but with large front chamfers to reduce edge diffractions for the mid-bass, which produces cleaner sound and better imaging. The slots of the Celata subwoofer design, the bottom two slots and the top two front-facing bass reflex ports are, of course, functional, and allow the speakers to be placed directly against walls.

Specifications
  • Dimensions including the Dynamic Waveguide: 353 mm x 717 mm x 448 mm, WxHxD
  • Weight: 46 kg each
  • Impedance: nominal 4 ohms, minimum 3.7 ohms at 38 Hz
  • Frequency range: 33 Hz (-3 dB) to 20 kHz
  • Sensitivity: 86 dB (1 m, 2.83 V)
  • Maximum power: 300 W peak, meaning very brief transients; equivalent to 35 V at 4 ohms. This results in a very high SPL, ~108 dB at 1 m from a single speaker, which is not recommended for the sake of your ears.
  • Crossover points: 130 Hz and 1300 Hz
  • Drivers: two 8-inch subwoofers; 7-inch mid-bass, graphene coated magnesium cone; 1-inch compression driver with oversized, 52 mm voice coil and mineral loaded ketone polymer diaphragm.
  • Dual, gold-plated, solid-copper binding posts. The top pair drives the Dynamic Waveguide and mid-bass; the bottom pair drives the subwoofers. This can be changed on request so that the top pair only drives the Dynamic Waveguide.
  • 2 x 9 V batteries are replaceable from the back of the speaker without tools. They require replacement at the end of the shelf-life of the batteries; 5 years for normal alkaline smoke detector batteries.
  • Recommended amplifiers: >40 W tube; >70 W solid state class A or A/B. More power is better. For bi-amping, 20 W tube is sufficient for driving the Dynamic Waveguide alone and could possibly drive the mid-bass, also, depending on the amplifier. The minimum impedance of the Dynamic Waveguide + mid-bass is 4.4 ohm at 220 Hz. The minimum impedance of the Dynamic Waveguide by itself is 8 ohm.
Features
  • 3-way, stand-mount passive speakers. By using a passive design, you can be sure that the speakers will not become obsolete as amplifier and connectivity technologies improve.
  • Made from responsibly sourced Australian timber species grown and processed or reclaimed and recycled in Australia.
  • Finishing options fall into three categories: popular, which we can always make or have on hand; limited, which are designs we’ve created to showcase timber with limited availability; custom—designs by you or your interior designer in consultation with us.
  • The patent pending Dynamic Waveguide design combines a cutting-edge waveguide profile in the horizontal dimension with a traditional horn profile in the vertical dimension. The result is the dynamics and intimate sound of a horn, but without horn honk colouration, combined with transparency and even horizontal sound distribution. That means instrumental and vocal timbres stay true from wall reflections even in reverberant rooms.
  • The graphene coated magnesium mid-bass driver remains pistonic across its range. It is critically damped in its own sealed enclosure so it doesn’t overshoot or ring. The result is crystal clear, lifelike vocals and instruments.
  • The patent pending Celata subwoofer design uses two horizontally opposed 8-inch subwoofers that are slot-loaded in a push-pull configuration to minimise cabinet vibration, overshoot and ringing. The result is exceptionally clean, crisp bass that is integrated perfectly with the mid-bass driver and Dynamic Waveguide, as opposed to using separate subwoofers that are virtually impossible to perfectly integrate with speakers.
  • The crossover is 18 V DC biased by two 9 V batteries to avoid distortion effects from capacitors. The components are the best we could find in the world based on 11 months of listening tests. For example, custom foil capacitors for the high and mid frequency circuits, copper foil for the high, and aluminium foil bypass capacitors for the mid. The result is very transparent sound—listen to music, not crossover artefacts. The crossover topology between the mid-bass and Dynamic Waveguide is quasi-transient perfect, meaning that phase is linear through the crossover region and the tweeter and mid-bass are perfectly time aligned, instead of the typical approach in which the midrange lags the tweeter in time. The subjective results of the time aligned Dynamic Waveguide and mid-bass are sharp, realistic transients which contribute to natural, engaging vocals and instruments.
  • The button on the back provides a treble boost designed to benefit listeners with hearing loss, particularly age-related, at high frequencies.
  • Matching speaker stands are available.
