Klipsch R-800F Review: A Research-Based Look

How we researched this: This guide is based on manufacturer specifications, owner documentation, published third-party measurements and professional reviews. We have not hands-on tested these speakers unless a section says so. Our methodology

How this review was made: we have not tested the R-800F ourselves, and we could not access an in-depth independent measurement of this model for this article. This analysis is therefore based on manufacturer data (Klipsch’s spec sheet figures and its R-800F product page) and our own design analysis. Where we interpret the specs, we say so.

The Klipsch R-800F is the largest tower in Klipsch’s current Reference series. It pairs Klipsch’s signature horn-loaded tweeter with two 8-inch woofers in a big, 54 lb cabinet, and it carries one of the highest sensitivity ratings in our catalogue: 98 dB.

That number needs context, because Klipsch measures it differently from most brands. Below we explain the in-room rating, how the horn tweeter shapes the design, why the rear ports matter for placement, and who this speaker suits best.

Verdict: an efficient home theater tower that needs room to breathe

On paper, the R-800F is built for movies. An 8-ohm nominal load, very high efficiency and dual 8-inch woofers mean almost any AV receiver can drive it to high volume. Its ±3 dB response figure (34 Hz–21 kHz) is also more meaningful than the unqualified ranges many budget towers quote.

The trade-offs are size and placement. It’s 17.5 inches deep, and its bass is ported out the back, so it needs space from the wall. And the horn tweeter’s character is a matter of taste: some listeners love its immediacy, others find it too forward.

Klipsch doesn’t say whether the R-800F is sold individually or in pairs, and retailers vary, so check current availability on Amazon and confirm the quantity in the listing.

Design and build

• Size: 43 × 10.9 × 17.5 in. (H×W×D). The depth is the number to watch; it needs a real footprint.
• Weight: 54 lb per speaker.
• Cabinet: Klipsch describes an MDF cabinet with a textured wood-grain finish, hidden fasteners and an edge-to-edge horn on the front baffle.
• Connections: hidden rear terminals designed for adding Klipsch Dolby Atmos modules later.

Drivers and cabinet

The horn-loaded tweeter

The defining feature of any Klipsch speaker is the horn. The R-800F’s 1-inch aluminum tweeter, using Klipsch’s Linear Travel Suspension (LTS), fires into a 90° × 90° Tractrix horn. Klipsch says the latest horn has larger outer dimensions than the previous design, for wider directivity control.

A horn works like a megaphone: it couples the small tweeter diaphragm to the air more efficiently, so the same amplifier power produces more sound. It also controls dispersion, steering sound toward the listening area and away from side walls and ceiling. In design terms, that tends to mean high efficiency, strong dynamics and less reflected sound from nearby surfaces. The “90 × 90” figure describes the horn’s intended coverage angle, horizontally and vertically.

Dual 8-inch woofers

Below the horn are two 8-inch spun-copper TCP (thermoformed crystalline polymer) woofers. Klipsch says the latest version uses steeper cone angling. Two 8-inch cones give much more radiating area than the two 6.5-inch woofers in the smaller R-600F, which is how the R-800F reaches a rated 34 Hz (±3 dB) versus 38 Hz.

The R-800F is a 2-way design: the woofers cover bass and midrange, and the horn tweeter takes over above the crossover.

Rear-firing Tractrix ports

The cabinet is bass reflex, with bass reinforcement from rear-firing Tractrix ports. Klipsch flares these ports with the same Tractrix profile as its horns, which is intended to reduce air turbulence and port noise at high output. Because the ports face backward, the wall behind the speaker becomes part of the bass system. More on that in placement below.

Specifications explained

The in-room sensitivity caveat

Most manufacturers measure sensitivity in an anechoic (echo-free) environment in “full space”, with sound free to spread in every direction. Klipsch quotes an in-room figure, measured in half-space (as if the speaker were mounted in a large flat boundary). Sound that would spread backward is effectively reflected forward, so the number reads several dB higher than a conventional rating of the same speaker.

In practice: don’t compare the R-800F’s 98 dB directly with the JBL Stage 280F’s 91 dB or a Polk’s 90 dB as if Klipsch were 7–8 dB more efficient. Even after mentally knocking off a few dB, though, the horn tweeter and 8-ohm load still put the R-800F among the easier towers to drive in our catalogue. Read more in speaker sensitivity explained.

Amplifier pairing

This is where the R-800F is at its most forgiving. Using Klipsch’s figure, just 10 watts would produce around 108 dB at 1 meter. Even allowing for the in-room caveat, a modest amplifier has plenty of headroom in a typical room.

• AV receivers: an 8-ohm nominal load suits virtually any receiver, including entry-level models, without special impedance settings.
• Stereo amps: low-power amplifiers, including tube amps, are realistic partners, which is part of Klipsch’s long-standing appeal.
• Power handling: 150 W continuous is a ceiling, not a target. Klipsch doesn’t publish a recommended amplifier range, so stay well within that rating and turn down if you hear harshness or distortion.

Because the horn is efficient, amplifier hiss can be more audible on very sensitive speakers; it’s worth listening for at your seat with no signal playing. Confirm your setup with our amplifier compatibility checker.

Placement and room fit

The R-800F is designed for medium to large rooms. In a small room, its bass output and 17.5-inch depth can easily overwhelm the space.

Wall clearance

Rear ports need breathing room. Too close to the wall and the port’s output combines with the wall reflection, which can make bass boomy and uneven. As a starting point, try 2 feet or more from the wall behind (measured from the back of the cabinet) and move it in or out in small steps. If bass is still too heavy at the spot you need, a subwoofer with the towers set to “small” in your receiver lets the sub handle the lowest notes, and you can place it where it measures and sounds best.

Toe-in and height

Horns control dispersion, so aim matters more than with many dome tweeters. Start with the speakers toed in so they point at or just beside your listening position, then adjust. Because horn treble can sound forward, slightly less toe-in is a common way to soften it.

How it compares

Specifications are manufacturer-published figures. Measurement methods differ between brands, so treat small differences with caution.

Klipsch R-600F: smaller and easier to place

The R-600F uses the same tweeter and horn with two 6.5-inch woofers. It’s rated at 96 dB in-room and 38 Hz–21 kHz ±3 dB, and it’s smaller (40 × 9.4 × 15.2 in., 41 lb). For small-to-medium rooms it’s the more sensible Reference tower; choose the R-800F only if you have the space and want more bass.

Klipsch RP-8000F II: the premium step up

The Reference Premiere RP-8000F II keeps dual 8-inch woofers but upgrades to Cerametallic cones and a titanium tweeter on a hybrid Tractrix horn, quoted to 25 kHz. It’s also rated 98 dB in-room and adds bi-wire/bi-amp terminals with Atmos passthrough. It’s bigger again (18.25 in. deep, 61.4 lb) and sits in a higher price tier.

JBL Stage 280F: the non-horn rival

The Stage 280F also uses dual 8-inch woofers, with a waveguide tweeter instead of a horn. JBL rates it at 91 dB (2.83 V, conventional method) and 6 ohms nominal, and its response is quoted at ±6 dB, a looser tolerance than Klipsch’s ±3 dB. It also uses rear ports and has a wide 14.1-inch base. Choose it if you want similar scale with a different tweeter approach.
