What the maker puts in writing
- “TRUE 2-WAY AUDIO PERFORMANCE: Features a 3.5” woofer with paper cone for clear mids and bass, paired with a 0.5” PEI tweeter for crisp highs, delivering superior sound compared to 1-way designs”
- “360-DEGREE SWIVEL BRACKETS: Easy-to-install wall mounts rotate in any direction, allowing precise sound staging”
- “Sleek 4.13” x 4.72” x 4.13” ABS cabinet weighs just 1.32 lbs per speaker… providing powerful 30W RMS output”
- “Ideal for 2.1, 5.1, or 7.1 surround systems, these speakers pair well with subwoofers”
- “Shielded grill protects against dust, with Euro block terminals for quick connections”
The swivel bracket is the reason to buy it
360-degree swivel brackets… rotate in any direction, allowing precise sound staging.
A surround speaker belongs high on a side or rear wall, above and behind the listener. From there it fires over your head unless it can be angled down and inward toward the seating.
A fixed bracket leaves it pointing straight across the room at the opposite wall.
The shelf, on this question:
This — 360° swivel
Polk ES10, $249 — screw inserts and keyhole slots for “directional firing”: a threaded insert takes a bracket bolt and holds at any angle, where a keyhole only hangs
B&W M-1, $325 each — vertical or horizontal, with an “adjustable tabletop” you aim
JBL C1PRO, $239 — “included brackets”, not described
Rockville RockSlim, $64.95 — “built-in brackets”, fixed
Bose, $399 — nothing stated
So one of the cheapest speakers here has the most adjustable fixing.
And the Euro block is better than its own stablemate’s terminals
Euro block terminals for quick connections.
A small plastic block with screw clamps: strip the wire, clamp it in, and the block plugs into a socket on the speaker.
It is what commercial installers use, for two reasons. The clamp holds far more securely than a spring clip — which takes bare wire only and weakens as the copper oxidizes underneath. And being removable, you wire the block at the bench and plug it in at the top of a ladder, rather than fiddling with bare strands while holding a speaker overhead.
The maker’s own RockSlim at $64.95 uses “spring-loaded terminals”. At least four listings here name no terminal at all, including the $399 Bose and the $325-each B&W.
A true two-way, which the bullet is right to flag
Delivering superior sound compared to 1-way designs.
A one-way speaker has a single full-range driver doing everything. At the top of its range a cone that size beams: the treble narrows into a cone pointing straight ahead, so the balance changes as you move — which on a surround speaker, heard from off-axis almost by definition, is the wrong failure.
A two-way gives the treble its own driver. Here a 0.5 inch PEI dome, which is small but is a dome.
PEI — polyetherimide — is a stiff engineering film: light enough to accelerate quickly and rigid enough not to flex, which is the usual compromise for a tweeter at this price.
Four inches cubed, and 8 ohms published
4.13” × 4.72” × 4.13” ABS cabinet weighs just 1.32 lbs per speaker.
Genuinely a cube, and the published weight is per speaker — against a catalog figure of 3 lb (1.4 kg) for the pair.
And the 8 ohm impedance is published, which only two other listings here manage: Polk (4 and 8 ohm) and B&W (8 ohm, in its description). Impedance is what tells you an amplifier can drive the speaker safely — most receivers are rated into 8 ohms, and at 8 ohms almost anything will do.
30 W RMS is modest, and for a surround channel it is usually sufficient: surround channels in a film mix carry ambience and effects rather than the main signal, and sit several decibels below the front three.
What is not published
No frequency response. The maker’s own RockSlim publishes 100 Hz – 20 kHz; JBL publishes 100 Hz – 18 kHz; B&W publishes 64 Hz – 23 kHz.
For a surround speaker a 100 Hz floor is not the limitation it would be on a front speaker — the receiver’s bass management sends everything below about 80 to 120 Hz to the subwoofer anyway. But without a figure you cannot tell where this one stops.
No sensitivity, which decides how loud it plays per watt. Only B&W publishes it, at 85 dB, in its description.
No peak power, where the RockSlim publishes 120 W per speaker alongside its 40 W RMS — and publishing both is what makes either number readable.
No cone material for the tweeter beyond PEI, and no crossover detail.
1,361 g the pair and 338 × 185 × 145 mm are the catalog figures, the latter evidently a carton.
