What the maker puts in writing
All four bullets, in full:
- “Exceptional Dialogue Clarity – Features dual 6.5” natural cellulose pulp midwoofers and a 0.98 in (25 mm) silk dome EFS tweeter for clear, lifelike voice reproduction and immersive midrange detail”
- “Powerful, Balanced Sound – The bass-reflex cabinet with dual front-facing vents enhances low-frequency response, delivering deep, rich bass without placement limitations”
- “Seamless Home Theater Integration – Designed for perfect timbre matching with other BOREA series speakers”
- “Versatile and Easy Placement – Compact design fits neatly under your screen; front-firing vents allow flexible shelf or cabinet positioning without compromising performance”
Two of those four are about the vents. On a center speaker, that is the right emphasis.
The front-firing vents are the one thing nothing else here has
A center channel is the only speaker in a system that always lives in a confined space: shoved into a television unit with its back near a panel, or pressed flat against a wall.
A rear port in that position is choked. Airflow is restricted, the bass compresses, and at volume the port can audibly whistle or chuff.
And the shelf is full of rear ports:
Sony SS-CS8M2, $248 — “rear bass reflex”
JBL Stage 2 245C, $439.95 — “dual rear-firing tuned ports”
Neumitech CS5, $89.99 — “its rear-ported design allow for a more compact design” — candidly admitting the reason is the cabinet, not the sound
Plus seven listings that say “bass reflex” or “ported” and never state which way.
Two products avoid the problem by having no port at all: the Goldwood AA35CB at $38.88 and Dayton’s C40 at $55.98, both sealed.
One fires forward. This one, and it says why — twice.
That is not a marketing line. It is the single most practical design decision on this shelf, and it means you can push the speaker back against the wall of a unit and lose nothing.
Dual six-and-a-half-inch cones, the largest here
Cone area goes as the square of the radius, so a pair of 6.5-inch drivers has:
about four times the area of a pair of 3-inch cones (Goldwood AA35CB, Micca OoO)
about 2.6 times a pair of 4-inch cones (Goldwood PSC-43, Dayton, both Miccas)
about 1.7 times a pair of 5-inch cones (Neumitech)
about 1.5 times a pair of 5.25-inch cones (Klipsch)
Only JBL’s four 4.5-inch drivers exceed it, at roughly 116 percent of this array.
On a center channel that buys the lower register of a male voice and the body of an impact — the part that makes dialogue sound like it comes from a person rather than a speaker.
Cellulose pulp, which is the damped choice
A cone has two contradictory jobs. It must be stiff, so it moves as one piece rather than flexing — flexing is breakup, and it adds frequencies that were never in the signal. And it must be damped, so resonance dies quickly instead of ringing.
Natural cellulose pulp — a paper composite — sits firmly on the damped side. Resonances are broad and gentle rather than sharp, which tends to sound forgiving and natural on voices.
The cost is stiffness: breakup begins lower than with a metal or composite cone, so the crossover must keep the driver below it.
The opposite choices on this shelf — aluminum (Yamaha), fiberglass (Neumitech), carbon fiber (both Miccas) — are stiffer, more analytical, and less forgiving of a harsh recording.
For a center channel, whose entire job is dialogue, the damped choice is defensible.
But measure the height
259 mm. The tallest cabinet on this shelf, and by a clear margin:
89 mm Polk · 132 Yamaha · 140 Dayton · 147 Goldwood PSC-43 · 155 JBL · 175 Micca OoO · 180 both Micca MB42X-C · 194 Klipsch · 216 Neumitech · 220 Sony · 245 Goldwood AA35CB · 259 mm this
The bullet calls it a “compact design [that] fits neatly under your screen”, which is generous. Twenty-six centimeters of clearance is more than many television stands leave.
And 25 lb (11.3 kg) — the second heaviest here after the JBL’s 26.5 lb (12 kg).
What four hundred and fifty-nine dollars does not tell you
No frequency response. Four products here publish one, and only Klipsch at $149.99 publishes a tolerance: “89Hz - 21kHz plus/- 3dB”. That is the only figure on the shelf you can rely on.
No sensitivity, which decides what amplifier you need — every 3 dB being a doubling of power. Klipsch publishes 95 dB; the four published figures here span a factor of eight.
No impedance and no power handling, where Klipsch publishes 400 W.
No crossover slope, and no off-axis treatment named — where Dayton and JBL publish 2.5-way crossovers and Neumitech names “off-axis lobing” outright.
So the comparison is uncomfortable and worth stating: the Klipsch at a third of the price publishes a full measured specification, and this publishes none. What the Triangle gives you instead is the largest cones on the shelf, 24.9 lb (11.3 kg) of cabinet, and the only forward-firing ports — which, in a tight cabinet, no figure can replace.
