Klipsch KL-525-THX — a Compact, Sealed-Box THX Ultra2 LCR
What distinguishes the Klipsch KL-525-THX from Klipsch’s other THX Ultra2 models in this family is its sealed enclosure: instead of a ported cabinet, it uses a sealed design that trades a bit of low-end extension for a smaller footprint and more placement flexibility on a shelf, stand, or wall bracket.
Cinema-Grade Drivers in a Compact Cabinet
Dual 5.25" Cerametallic™ woofers handle bass and midrange, and a 1" titanium dome compression driver is mated to a 10" by 6" rectangular 90° x 60° Tractrix® horn — the same horn-loading philosophy Klipsch uses on its professional cinema speakers, scaled for a smaller cabinet.
THX Ultra2 Certified for Reference-Level Performance
THX® Ultra2 certification means the KL-525-THX has been tested to reproduce a soundtrack’s full dynamic range cleanly, even at reference playback levels, in the larger rooms that certification targets. It’s timbre-matched to the rest of Klipsch’s THX Ultra2 lineup, so it mixes and matches cleanly with in-wall or in-ceiling models elsewhere in a system.
Let’s Design Your Ottawa Home Theater System
Since a THX Ultra2 speaker like the KL-525-THX is typically specified as part of a larger custom install, I’d invite you to book a design and installation consultation with our Ottawa team. We’ll help you decide where a sealed-box design like this makes more sense than a ported model, and how many channels your room calls for.

Frequently Asked Questions
Why choose a sealed design like the KL-525-THX over a ported model?
A sealed enclosure generally allows more flexible placement (including closer to a wall) since there is no port to keep clear, at the tradeoff of slightly less low-frequency extension than a similarly sized ported design.
Is the KL-525-THX sold individually or in pairs?
It’s sold individually so your installer can order exactly the number of channels your design calls for — talk to us about how many you need for your specific room.
