Description
Klipsch THX-504-L White, Each
Product Details
The THX-504-L is a THX® Select certified loudspeaker. Certification is not a badge — it is a measured standard for output, distortion and frequency response at reference level in a room of a defined size, which is why THX-certified speakers are specified for rooms where the cinema reproduction has to be accurate rather than merely loud.
It uses four 5.25" (13.3cm) high-output, fiberglass cone woofers with a 1" (2.5cm) Titanium diaphragm compression driver mated to 90° x 90° square Tractrix® horn. The horn is symmetrical, which gives flat in-room response with high efficiency and low distortion — the combination that lets a speaker hit reference level without strain.
Every THX speaker in the range is timbre-matched to the others, so an LCR front stage, surrounds and in-wall fills can be mixed across models without a tonal seam between channels. An edge-to-edge grille covers the whole speaker — simpler to paint, held by neodymium magnets with no moving parts, and flat enough to disappear into a modern interior.
