Bass-Extended Speaker
In DevelopmentReference One architecture extended downward — a dedicated bass unit for rooms that want full-range sound without a subwoofer.
Internal ID: speaker-extended

Design highlights
- Identical mid/high module to Reference One, so timbre is shared across the range.
- Dedicated bass unit with its own alignment, tuned for real rooms rather than anechoic show.
- Floor-standing geometry kept narrow to preserve the controlled directivity of the upper drivers.
- Single-amp friendly: no active electronics required, DSP presets available via Amp One later.
The idea
Some rooms — and some listeners — want the full octave range from a pair of speakers with no subwoofer in the chain. Extended One keeps the entire mid and high structure of Reference One untouched and adds a dedicated bass section below it, voiced to integrate in ordinary rooms.
Design notes
The bass unit runs its own alignment. It hands over to the Reference mid-bass driver low enough that directivity is already omni-directional on both sides of the crossover, so room interaction stays smooth. The enclosure is a floor-standing column whose baffle width is kept to the Reference module, so the controlled-directivity story of the upper octaves is not compromised by a wider cabinet.
Everything above 300 Hz is shared with Reference One. That means the two models can coexist in one system — centre channel, second room, surround — without a timbre discontinuity.
What we measured
Extended One is in early concept and simulation. No measurement archive exists yet; when it does, it will appear under Measurements with the same evidence labelling as every other record.
