Up-firing needs a ceiling; in-ceiling needs a drill · review
An upfiring Atmos height pair with 3.94 inch full-range drivers, matched to Sony CS speakers.
In brief
A single full-range driver and no tweeter at all, for $208 on October 25, 2026 — where the Klipsch at $199 has both. It is matched to Sony speakers and receivers, which is its argument. Key figures: Dolby Atmos enabled upfiring height speaker pair with 3.94 inch full-range drivers and a reinforced cellular cone, wall-mountable, stated matched to Sony SS-CS5M2 and SS-CS3M2 speakers and Sony AV receivers. Amazon.com had an offer at $208 on October 25, 2026.
3.94 in. full-range speakers.
One cone covering bass through treble. No separate tweeter.
What that buys you: no crossover. Nothing splits the signal between two drivers, so there is no phase discontinuity at the handover frequency, and no filter components in the path.
What it costs you: the top end. A four-inch cone is heavy and wide for reproducing 15 kHz — the treble rolls off and becomes directional as frequency rises.
And on a ceiling-bounce speaker that compounds, because the reflection off the ceiling already absorbs high frequencies. It is why two products here — Klipsch’s RP-500SA and the JBL — fit a switchable crossover that adds treble for the bounce path. A full-range driver has no crossover to switch.
At least eight of the thirteen products here use a tweeter plus a woofer. The $199 Klipsch R-41SA gives you a 1-inch aluminum LTS tweeter and a 4-inch IMG woofer for seventy-nine dollars less than this.
Perfect match with SSCS5M2 & SSCS3M2 CS Speakers. Sony CS speakers are a perfect match for Sony AV receivers.
This is not empty. An Atmos effect frequently pans from a front speaker up to a height speaker — a jet passing over. If the two speakers use different drivers, the sound changes tone as it moves, and the overhead illusion collapses.
Within one range the drivers share cone materials and voicing, so the pan is continuous.
Polk makes the same case and names its models. Klipsch says only “compatible bookshelf or floorstanding speakers”.
The flip side is the lock-in: a matching argument is also a reason to buy the rest of the range.
Each cabinet is 7.09 × 7.01 × 5.71 in (180 × 178 × 145 mm) — about 4.6 liters — and holds a 3.94-inch driver with a magnet.
The magnet alone on a four-inch driver typically runs 150 to 300 g (5.3 to 10.6 oz), and there are two. Then two cabinets.
From this shelf, comparable boxes: ELAC 5.5 lb (2.5 kg) · Polk XT90 6 lb (2.7 kg) (also a 4-inch pair) · JBL 7.7 lb (3.5 kg) · SVS Prime 7.8 lb (3.5 kg).
The only other sub-kilogram figure here is Klipsch’s RP-140SA at 340 g (12 oz), which is also impossible. Both are round and both are far too light — catalog placeholders rather than measurements.
No power handling, where Klipsch publishes “50 watts continuous and 100 watts peak” and the RP-500SA gives 75 W.
No impedance, where Klipsch states 8 ohm and Polk states compatibility with 4 and 8 ohm receivers.
No minimum receiver channel count — only Polk publishes that, and it is the fact that decides whether you can connect a height pair at all: it needs two amplifier channels on top of your existing five, so a 5.1 receiver cannot drive it.
No horn or waveguide, where Klipsch uses a Tractrix horn and ELAC a concentric driver, both to aim the energy at a specific patch of ceiling.

It is a real trade, and this is the only product on the shelf making it. Sony publishes "3.94 in. full-range speakers" — one driver covering bass through treble, with no separate tweeter. The advantage is genuine: there is no crossover, so nothing splits the signal between two cones and there is no phase discontinuity where they hand over. The cost is at the top end — a four-inch cone is heavy and large for reproducing 15 kHz, so the treble rolls off and becomes directional. On a ceiling-bounce speaker that compounds: the reflection already absorbs treble. At least eight of the thirteen products here use a tweeter plus a woofer, and the $199 Klipsch gives you a 1-inch aluminum tweeter and a 4-inch woofer for seventy-nine dollars less than this.
It is almost exactly one pound, which is a figure worth doubting. Each cabinet measures 7.09 × 7.01 × 5.71 in (180 × 178 × 145 mm) — roughly 4.6 liters — and contains a 3.94-inch driver with a magnet. The magnet alone on a four-inch driver typically runs 150 to 300 g (5.3 to 10.6 oz), and there are two of them. Add two cabinets. From this same shelf, with comparable cabinets: ELAC 5.5 lb (2.5 kg), Polk XT90 6 lb (2.7 kg) for a 4-inch pair, JBL 7.7 lb (3.5 kg), SVS Prime 7.8 lb (3.5 kg). The only other figure under a kilogram here is Klipsch’s RP-140SA at 340 g (12 oz), which is also impossible. Both round, both too light; treat 454 g (16 oz) as a catalog placeholder rather than a measurement.
Something real, and it is this listing’s strongest point. Sony names it twice: "perfect match with SSCS5M2 & SSCS3M2 CS Speakers" and "Sony CS speakers are a perfect match for Sony AV receivers". The acoustic reason is that an Atmos effect often pans from a front speaker up to a height speaker — a jet crossing overhead — and if the two use different drivers, the sound audibly changes tone as it travels, which breaks the illusion. Within one range the drivers share materials and voicing, so the pan is seamless. Polk makes the same case and names its models (MXT20, MXT60, MXT70). Klipsch says only "compatible". The cost, of course, is that the argument also sells you the rest of the range.
