Four height channels, which nothing else here has
A channel count reads front . sub . height. So 5.1.4 is five horizontal channels, one subwoofer and four height channels.
And Klipsch states where they go: height effects from the front AND back.
That is what an Atmos mix is written for. A sound placed overhead moves between front and rear positions — a helicopter crossing, rain spreading across a ceiling, a voice from a gallery above and behind.
Now the rest of this shelf:
R-625FA bundles — $1,298, $1,799.99, $2,198.99 — floorstanders with “built-in up-firing elevation channels”: two height channels, both at the front
Energy $275 and $749 · Sony $329 · Yamaha $499.99 and $749.95 · Klipsch Theater Pack $549.99 — no height channels
This, $749.99 — four
So the cheapest product here with any Atmos has twice the height channels of the one at two and a half times the price.
The horn angle is published, which matters on a height speaker
Exclusive Tractrix 90° × 90° horn technology.
Two Klipsch listings on this shelf publish the angle; the Theater Pack at $549.99 does not.
A horn does two things. It aims the treble into a defined angle rather than letting it spray unevenly — ninety degrees horizontally and ninety vertically here. And it raises efficiency, by coupling the small dome more effectively to the air.
On a height speaker the aiming is the point. An Atmos height effect works by bouncing sound off the ceiling or by firing down from one, and a treble pattern that is predictable over a known angle is what makes the reflection land where it should.
The efficiency half is why Klipsch systems are easy to drive — and the R-620F pack at $988.89 publishes the proof: 96 dB sensitivity, the only such figure on this shelf.
But nine amplifier channels are needed, and the listing does not say
A 5.1.4 layout wants five channels for left, center, right and two surrounds, plus four for the heights. Nine in total.
That is a higher class of receiver than most of this shelf bundles.
The Denon AVR-S670H in two bundles here is 5.2 — it cannot drive this system. The Onkyo TX-NR7100 in the two most expensive bundles is 9.2, which can.
And the references price them: Onkyo $501.99, Denon $474.
So the honest cost of this system is around $1,250 — still less than the $1,799.99 bundle, which pairs a 9.2 receiver with only two height channels and leaves two amplifier channels unused.
The trade is cone area at the front
Satellites, where the R-625FA bundles use floorstanding towers.
A tower has multiple woofers of 5.25 to 6.5 inches and a cabinet of thirty or forty liters. A satellite has one small driver and perhaps two.
The difference shows in two places. Midrange weight — the body of a male voice and the lower register of music sit around 100 to 300 Hz, which a small satellite hands to the subwoofer; and a subwoofer in a corner is the wrong source for a voice. And output before distortion, since a small cone must travel further for the same loudness.
What satellites buy back is placement, which on a system with four height speakers is not a small thing: they have to go on walls or ceilings regardless, and Klipsch’s own Theater Pack at $549.99 sells “an incredibly minimal footprint” on exactly that basis.
And the subwoofer amplifier is named but not measured
The built-in all-digital subwoofer amplifier delivers ample power with high efficiency.
“All-digital” means a class D amplifier: it switches rather than dissipating, so it runs cool and small and wastes little power as heat. That is the right choice inside a sealed subwoofer cabinet, where there is nowhere for heat to go.
No wattage is published. The Energy subwoofers on this shelf publish 200 W; the Klipsch R-12SW in the larger bundles is given as 400 W — and one of those bundles clarifies it as “400W peak”.
Thirty kilograms exactly is the published weight, which is a round metric figure rather than a measurement.
What is not published
No subwoofer power, no driver sizes, no sensitivity, no frequency response, no impedance.
No receiver channel requirement, which on a 5.1.4 system is the single most consequential omission — a buyer with a 5.1 or 5.2 receiver cannot use this at all.
No warranty, where the R-620F pack and R-625FA pack both publish a 5-year limited warranty.
417 × 1422 × 368 mm is published, evidently a carton.
