The Black Crown Modular Platform — Technical Details & Specifications

Built for Real Rooms

This modular speaker system was designed for actual living rooms — not treated listening rooms or free-field setups. The goal was simple: create speakers you can drop into a regular family room and still get great imaging, clear detail, and bass that doesn't bloat.

Bonus: They're toddler-resistant. Knocked over, poked at, and still performing.


How the System Works

The system is built around a standalone 2-way bookshelf speaker that you can use on its own or expand with modular components:

  • Salon: 2-way bookshelf (standalone)
  • Bass Module: Optional woofer unit for extended bass
  • Air Module: Optional super tweeter for extended highs

When fully stacked, each speaker has 4 passive drivers, all waveguided and physically time-aligned — no DSP needed.


Technical Specifications

Performance (In-Room Testing)

  • Usable frequency range : ~35Hz to 17kHz
  • F3: 46Hz / F10: 32Hz
  • THD: Under 1% in mids and treble @ 95dB
  • Max SPL tested: Clean to 100dB (tested with a 350wpc Hypex amp)
  • Port tuning: ~41Hz around F6
  • Port noise: No audible chuffing at 95dB (tested with house music)
  • Impedance: All drivers are 8 ohm

Design Features

  • Waveguided drivers
  • Physical time alignment (no DSP required)
  • L-pads on tweeters for voicing and/or room tuning
  • Removable bracing — easy to mod or service
  • Modular stacking system

What It Sounds Like

These speakers were tuned for long listening sessions in untreated rooms:

  • Imaging: Stays solid at any volume from 55-100db
  • Treble: Fatigue-free during long 80–85dB sessions
  • Bass: Tight and surprisingly deep — no subwoofer needed for most music
  • Room flexibility: L-pads help dial in symmetry and imaging for your specific space

Amplification note: Tested with all amp types. Class D amps work great — the speakers smooth out the clinical edge.


What We Tried (and Removed)

During development, we tested several common audiophile approaches. Here's what didn't make the cut:

  • Subwoofer: Just bloated the low end in normal rooms
  • Extra damping: Removing 30% of the damping: bass became too tight and lean
  • Baffle Step Compensation: Caused a huge mid-bass hump. Driver selection did the job better.
  • Room correction / DSP: Degraded clarity and staging. L-pads and physical setup worked better.

Built for Real Life

This is a speaker system designed for how people actually listen — in living rooms with furniture, family, and life happening around them. No magic, no fairy dust. Just thoughtful design, real-world testing, and a modular approach that lets you scale performance to your space.
