Product Description

Klipsch KS-7800-THX Ultra2 In-Wall Surround Speaker – Each

Klipsch engineered the KS-7800-THX to give you real cinema sound while disappearing visually. Specially designed as an in-wall surround speaker, the Klipsch KS-7800-THX creates the same wraparound, atmospheric effect as on-wall speakers. Its hideaway in-wall design and paintable grille integrate seamlessly into just about any room. Plus, the KS-7800-THX bears the THX Ultra2 seal of approval, which means it can produce crisp, clear sound at highly demanding reference levels in rooms as large as 3,000 cubic feet.

Horn technology for focused sound

The Klipsch KS-7800-THX uses two vertically stacked horn-loaded tweeters to create an enveloping soundfield wih precise localization of effects. Klipsch’s Tractrix horn design has a flared opening, and the two tweeters fire away from each other to project sound in a specified pattern. This approach produces an expansive soundstage that enhances both movie soundtracks and music. An 8″ aluminum woofer pumps out detailed, low-distortion mids and solid bass.

An integrated enclosure ensures accurate sound

The space behind a speaker’s drivers can directly affect the sound you hear out front. So how do you know the Klipsch KS-7800-THX will reproduce movie soundtracks accurately, when it’s installed in the wall in your particular home theater room? Klipsch’s answer is an integrated back box enclosure, which ensures that the KS-7800-THX’s response is consistent, no matter what kind of space happens to exist behind your wall. And because this enclosure fits easily within the loudspeaker’s cutout footprint, the Klipsch KS-7800-THX can be installed into new or existing construction.

Enveloping Sound Fields and Precise Localization of Individual Effects

In order to create enveloping sound fields and precise localization of individual effects, this speaker also utilizes Klipsch’s Wide Dispersion Surround Technology™. Also referred to as WDST, this no-compromise approach gives the KS-7800-THX much more placement flexibility than conventional designs. Featuring an integrated back box enclosure, the KS-7800-THX’s response is both predictable and repeatable. Because this enclosure fits easily within the loudspeaker’s footprint, the KS-7800-THX can be installed into new or existing construction.
