Product Description

The Klipsch Professional Series introduces a new line of high-performance architectural speakers unlike any you’ve heard before. Superior acoustic technology makes the Professional Series the most dynamic, powerful, direct-radiating speakers available.


Need to fill your Ultimate Home Theatre with THX Certified sound quality from hidden speakers. The Klipsch PRO-6504-L-THX could be exactly the left, centre and right channel speakers you've been looking to purchase. With a set of these speakers, your journey to great sound doesn't need to be riddled with visual obstacles like large free-standing speakers. The architectural design will deliver awesome sound and integrate into almost any room. Just add the subwoofers!

The Klipsch PRO-6504 speaker bears the THX Select2 seal of approval and although this doesn't mean George Lucas has them in his own hoe theatre it does mean it can produce crisp, clear sound at highly demanding reference levels even in large rooms. You can install a pair to the left and right of your big screen, flat-panel TV and add a subwoofer or even add a third horizontally as your centre channel speaker for stunning sound. So what's inside?

First, let's look at the titanium horn-loaded tweeter. This is mated to the woofers using precision-voiced high-definition crossover networks creating high sensitivity. This makes the speaker easier to drive so it requires a lot less amplification power than conventional designs. The high-efficiency design of the Klipsch in-wall speakers allows you to get much more output than most other in-wall and in-ceiling speakers. The 92dB efficiency of this speaker means it will play much louder at low power than other less-efficient speakers. A flared horn opening projects high frequencies toward your listening area and prevents sound waves from simply spilling out in all directions. This horn design helps the speaker reproduce accurate detail with everything you listen to, while reducing reflections that can color the sound. The horn also improves dynamics and efficiency, for powerful, "front row" sound that remains crystal clear at all volume levels.

3-Way Speaker Design: The PRO-6504-THX uses a premium 25mm Titanium compression driver (tweeter) mated to an exclusive Tracery Horn, combined with four 133mm fiberglass woofers in a 3-way design.

  • Titanium Tweeter: The PRO-6504-THX utilises a 25mm Titanium dome compression tweeter mated to a 102mm square, Tracery Horn, which disperses the sound 90° horizontally and 90° vertically into the room. The horn design dramatically increases efficiency by enabling the speaker to produce more output using less energy.
  • Four Woofers: The PRO-6504-THX employs four high-output 133mm fiberglass cones for powerful bass impact.

Other Features

The PRO-6504-THX has a sturdy ABS frame assembly and a deluxe MDF baffle with brushed aluminum fascia. The frame and metal mesh grille can be painted to match any decor. The speaker has a gold-plated pair of spring-loaded binding posts that can accept up to 12-gauge bare wire or single banana plugs. Klipsch specify the maximum power handling of this speaker as 150 Watts RMS and the recommended amplifier power specification is somewhere between 140 Watts to 200 Watts full band-width power per channel. In other words, you will need a high-end AV Receiver or additional power amp.

Maximum Installation Reliability: The speaker also consistently delivers thrilling, realistic sound, whether it’s installed horizontally or vertically. It features sure-grip mounting that provides even pressure against plasterboard for long term installation reliability and includes a paintable grille that blends in perfectly with any décor.

Unlimited Flexibility: Timbre matched to all of Klipsch THX-certified products, so you can mix and match to create an unbeatable, discreet stereo or home theatre system that’s just right for you.

Edge-To-Edge Grille: Covering the whole of the speaker makes painting the product both simpler and quicker. Premium Neodynium magnets make it easy to install and remove and ensure a secure and flush fit without any moving parts. The flat grille allows better harmonisation with today’s modern interior designs and disappears into the background, enabling sound to take centre stage.
