BRICASTI DESIGN S7 Speaker

Product overview

The BRICASTI DESIGN S7 Speaker is a passive 3-way bass-reflex floorstanding loudspeaker with a 25 mm beryllium dome tweeter, a 74 mm carbon-fibre dome midrange and dual 7.5 in woven carbon-fibre woofers, reaching -2 dB at 32 Hz.

The S7 was inspired by a desire to create a system that is inherently balanced in terms of size and performance, using the latest technologies available. Countless hours of critical listening and patience went into its development, to create an experience that brings music to life. It stands 45 in (1143 mm) tall, weighs 120 lb (54.4 kg) each and rests on machined aluminium outriggers with integrated isolation devices.

Key features

• True 3-way architecture: passive bass-reflex design with a 25 mm beryllium tweeter, 74 mm carbon-fibre dome midrange and dual 7.5 in woven carbon-fibre woofers
• Full-range authority: controlled low-frequency extension to -2 dB at 32 Hz, without external reinforcement
• Precision driver integration: matched diaphragm materials and crossover refinement for coherence from bass to treble
• Stable and system-friendly: 89 dB sensitivity with a 4 Ω nominal impedance, for high-performance amplification
• Substantial construction: 45 in tall and 120 lb each, with integrated isolation devices and a vibration control platform
• Dedicated ported bass sub-enclosure, separate from the midrange and tweeter chamber
• Machined aluminium outriggers for structural stability
• Finishes: Gloss Black, Matt Black or White

Precision in motion

Driver selection was approached as a system-level decision rather than a checklist of premium materials. The woofers and the 3 in dome midrange use advanced spread-tow carbon-fibre diaphragms, chosen for their exceptional stiffness-to-mass ratio and low stored energy. For the high frequencies a 1 in beryllium dome tweeter was selected: its extremely low moving mass allows rapid transient behaviour and precise integration with the midrange, for a coherent and seamless upper spectrum.

Low distortion

The dual 7.5 in woofers operate within a dedicated ported sub-enclosure, physically separated from the midrange and tweeter chamber to preserve clarity and reduce interaction between frequency bands. The result is controlled low-frequency extension with composure and stability, paired with an open and unforced midrange presentation.

Separation

The crossover network was carefully developed and extensively refined to maintain phase integrity and tonal balance between the drivers, with every component selected and implemented for long-term reliability and consistency.

Isolation and stability

A set of isolation devices is part of the S7's mechanical foundation, mated directly to the newly developed BRICASTI DESIGN vibration platform to form a unified interface between the loudspeaker and the floor, enhancing energy dissipation, lowering structural resonance and preserving clarity under dynamic load. Machined aluminium outriggers increase structural stability while helping manage cabinet and floor-borne energy.

Workflow 1: A complete BRICASTI DESIGN system

Listeners building a system around BRICASTI DESIGN electronics.

Connections

Setup

1. Place the S7 pair symmetrically in the room.
2. Connect each S7 to its amplifier channel, observing polarity.
3. Power up the electronics.
4. Fine-tune placement by listening.

Tip: A pair of monoblocks such as the M28 or M30 drives one S7 each.

Workflow 2: Full-range listening without a subwoofer

Rooms where a separate subwoofer is not wanted.

Connections

Setup

1. Connect the S7 pair.
2. Play music with deep bass.
3. Adjust distance to the rear wall.
4. Enjoy extension to -2 dB at 32 Hz.

Tip: The S7 delivers scale and foundation without external reinforcement.

Workflow 3: Driving a 4 Ω loudspeaker

Choosing an amplifier for the S7.

Connections

Setup

1. Check that the amplifier is rated into 4 Ω.
2. Connect with good speaker cables.
3. Set the level at the preamplifier or DAC.
4. Listen.

Tip: 89 dB sensitivity and 4 Ω nominal impedance suit high-performance amplification.

Workflow 4: Installation on hard floors

Rooms with tiled, stone or wooden floors.

Connections

Setup

1. Unpack with two people: each S7 weighs 54.4 kg.
2. Set the S7 on its outriggers.
3. Check that it stands firmly.
4. Position and listen.

Tip: The isolation feet and vibration platform form one interface between speaker and floor.

Workflow 5: Matching the room

Choosing a finish.

Connections

Setup

1. Choose Gloss Black.
2. Or Matt Black.
3. Or White.
4. Order the pair in one finish.

Tip: All three finishes share the same drivers and construction.

Workflow 6: Stereo imaging set-up

Listeners optimising the stereo image.

Connections

Setup

1. Form an equilateral triangle with the listening seat.
2. Keep the same distance from side walls.
3. Adjust toe-in by listening.
4. Check polarity on both speakers.

Tip: The coherent driver integration rewards careful placement.
