Music for York House

Relative price

above typical

Among the 26 loudspeakerss in the catalogue, this one is above typical.

A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.

What it is

ASC-2 parity entry. Crossover brief + max-SPL analysis [437]; driver survey [12377]–[12871]; woofer datasheet verification [15591]; audit [439][441].

Connectivity: external passive crossover per side, three driver-side output pairs (tweeter/mid/paralleled woofers), separate bass + mid/treble INPUT terminals — linked single-amp or unlinked bi-amp [416].

D9 RESOLVED (11 Jun): void_fitted=True — gate/rules check the physical envelope; no exemption needed.

CHARACTER (predicted, Stage-2 to confirm): neutral/calm/holographic/low-level-resolving; NOT characterful; small negative drive delta. Switchable-character footnote: defeatable shelf engaged → reversible +romantic delta.

FRONT-END VETTING (spec estimate §2): at ~93dB/2.83V the NOISE FLOOR is the binding constraint (habitual draw ~5–50mW) — minimal-total-gain structure favoured (TVC+Proprius well matched); the 1:40 SUT chain carries the highest hum/noise risk — vet placement+grounding hardest; confirm Fidler subsonic filter engaged (protects amp swing <30Hz); 3510 contingency gated on recess ≥340–350mm (predicted cavity-edge veto until drawn).

D9a BAY (LOCKED 11 Jun): per-void service bay 140W×315H×250D holds, front-to-back: 2× Proprius stacked on top (105×~125×205, right-angle XLRs mandatory — 250mm depth); XO box below, tall-shallow ~130×170×170; both 48V bricks stacked depthwise (85×170×80) in the rear slot behind the box. ~20mm stack margin.

HEAT (pair-discussion REQUIRED content): amps are the real source (~20-30W continuous, est.) → chimney venting inlet low/front outlet high/rear, amps top of stack; brick slot vented (SMPS electrolyte life); XO pads spec 10W+ wirewound; speaker thermal a non-issue at user levels (60W/driver rating vs <1W average).

EMI (pair-discussion content): XO coil axes alternated, ≥coil-diameter spacing (the slim box makes this the layout constraint); thin steel divider between brick slot and box rear; twisted+ferrited DC leads; mains enters opposite side from XLRs, right-angle crossings. Brick architecture = no mains transformer near coils (advantage). Phono path nowhere near (across room).
