01 · KEF UNI-Q + MAT12th-gen 5.25″ coaxial point source with Metamaterial Absorption Technology.
02 · MATRIX BRACINGInternal braces cut 2 mm shy of every wall so structural joints never rigidly couple.
03 · BUTYL CLD DAMPINGConstrained-layer butyl mastic fills every 2 mm gap—KEF's own LS50 damping method, built by hand.
04 · FLEXIBLE PORT3-piece PETG flares joined by a soft neoprene sleeve tuned to 46.7 Hz, killing pipe resonance.
05 · HIGH-DENSITY SHELL¾″ Fibralux Black MDF (870 kg/m³), glued airtight with zero screws and volume-audited to 0.01%.
06 · PASSIVE ACCESSKEF's crossover stays inside, wired to angled binding posts so any external amp can drive them.
07 · WHITE OAK BAFFLESolid white oak front with a proud matte-black driver plate and precision shadow reveals.
08 · CUSTOM RAKE ANGLEBase cut to your seated ear height so the acoustic axis aims straight at your ears.
ADAU145248 kHz real-time audio processing
TPA3221 × 2340 W power amplifier
01 · THE PLINTHSteel-shot ballasted base housing the DSP and dual amps behind one power cord, cooled by a silent bottom-to-rear chimney.
02 · 10″ SEALED SUBDown-firing Dayton MX10-22 in a braced 13″ enclosure—taking deep bass off the KEF cones so midrange stays pure.
03 · MODULAR DOCKSolid white oak standoffs align directly over the plinth's four recessed mortises.
04 · COUPLEDOne compact footprint under the desk. Zero external amp racks.
A 10-inch sealed sub, firing into its own plinth.
It takes the deep bass off the woofer, which keeps the mids clean.

Measured
The measurements.
Every room distorts bass below 300 Hz. Using a calibrated microphone at your seat, the ADAU1452 DSP time-aligns the sub, cuts room modes, and locks in a smooth in-room contour.
