What the maker puts in writing
- “Powerful dual 8” woofers provide optimal linear movement resulting in a low frequency bass performance that is clean, deep and controlled”
- “Ultra high-end Neodymium tweeters produce high frequencies with captivating clarity”
- “Unique midrange pointed dome allows sound waves to travel directly from the center of the woven glass fiber cone for an enhanced soundstage”
- “Acoustically inert, the cabinets are precision crafted with engineered MDF wood to create a warm, distortion-free sound; A solid 1.4” thick front baffle bears chamfered edges to significantly decrease sound diffraction”
- “the Signature Series uses only premium components that ensure high fidelity sound”
Eight-inch woofers, which nothing else here has
Radiating area goes as the square of the radius, so (8 ÷ 6.5)² = 1.51 — half again as much air moved for the same cone travel as a 6.5-inch driver.
Two consequences you hear: it reaches lower before the driver runs out of excursion, and it distorts less at any given loudness, because the cone travels a shorter distance for the same output.
The shelf, by woofer size:
5.25 in × 3 — NHT, $749.99 each
6.5 in × 2 — Dayton $229.98 pair, Fluance Ai81 $599.98 pair
6.5 in × 1 driven + 2 passive — Polk, $249
6.5 in — Rockville $119.95 pair, Energy $799.98 pair
6.5 in × 3 — KEF, $1,249.99 each
6.5 in × 4 — SVS, $3,998 pair
8 in × 2 — this, $799.99 pair
Two 8-inch cones give roughly the same total area as three 6.5-inch ones — so this matches the KEF’s three and sits a little under the SVS’s four, at a fraction of either price.
The pointed dome is a phase plug, and the explanation is right
Unique midrange pointed dome allows sound waves to travel directly from the center of the woven glass fiber cone.
The problem it addresses: a conventional cone has a dust cap over the voice coil, and at higher frequencies that cap and the surrounding cone radiate slightly out of step with each other, producing cancellations on axis.
Replacing the cap with a rigid pointed dome fixed to the magnet assembly removes the cap’s contribution and guides air outward from the center — smoothing the response and widening dispersion. It also conducts heat away from the voice coil.
It is a technique more common in professional drivers than domestic ones, and nothing else on this shelf publishes it.
And the baffle specification is the only one here
A solid 1.4” thick front baffle bears chamfered edges to significantly decrease sound diffraction.
Two different ideas, both sound.
Thickness. The front panel carries the drivers, and every time a cone pushes forward it pushes the baffle back. A thin panel flexes, which smears the driver’s motion and radiates sound of its own. At 1.4 inches — roughly 35 mm — it does not.
Chamfering. Sound traveling along the baffle reaches the cabinet edge and diffracts, re-radiating as though from a second source and creating response irregularities. Rounding or beveling the edge softens that transition.
Two other listings attack the same problem differently. NHT uses the narrowest baffle on the shelf — 7.24 in (184 mm) — so there is less panel for sound to travel along. KEF publishes “Shadow Flare geometry [to keep] high frequencies pure”.
A pair, which three listings here are not
$799.99 for two speakers, stated “/Pair” in the title.
Worth spelling out, because the price order on this shelf misleads:
Rockville $119.95 (pair) · Dayton T65 $229.98 (pair) · Polk T50 ~$498 (pair, title singular) · Fluance Ai81 $599.98 (pair, powered) · Energy $799.98 (2-pack) · this $799.99 (pair) · NHT $1,499.98 (pair, “single unit” listed) · Focal $1,993.90 (pair, “sold individually”) · KEF $2,499.98 (pair, “sold individually”) · SVS $3,998 (pair)
So a three-way pair with 8-inch woofers at eight hundred dollars sits against a three-way NHT pair with 5.25-inch woofers at fifteen hundred, and a KEF pair with 6.5-inch woofers at twenty-five hundred.
And it is the tallest cabinet here
1,201 mm. Against Polk 921 · Fluance Ai81,960 · Dayton 1001 · NHT 1022 · KEF 1062 · Focal 1122 · Rockville 1181 · SVS 1182 mm.
Height is not decoration. Dayton gives the reason on this same shelf: a tower stands tall “precisely placing the tweeter at ear level”, and a seated listener’s ears sit roughly 38 to 42 inches — 38 to 41.9 in (965 to 1,065 mm) — from the floor. Treble beams, so a tweeter at the wrong height audibly loses the top end.
At 47.3 in (1,201 mm) with a three-way layout, the tweeter will sit near the top — comfortably in range.
28,304 g the pair is published, which with a 35 mm baffle is consistent.
What is not published
No enclosure type. This is the conspicuous gap, because five other listings state theirs and each explains a different strategy: NHT sealed · Dayton bass reflex · Focal front and rear vents · Fluance’s own Ai81 down-firing ports · KEF ported with bungs to seal it near a wall. This says nothing, so you cannot tell whether wall proximity will matter.
No dome material. “Neodymium” names the magnet — a rare-earth material far smaller and stronger than ferrite for the same force, which allows a more compact tweeter and tighter driver spacing. Both Fluance models here say it. Neither says what the diaphragm is made of, where Dayton publishes silk, NHT aluminum, SVS diamond-coated aluminum and Focal an inverted aluminum-magnesium M-dome.
No frequency response. Only KEF publishes one, with the shelf’s only tolerance: “37Hz (-6dB), with in-room bass extending to 26Hz”.
No sensitivity, no impedance, no power handling — where the Rockville at $119.95 publishes the last two and KEF the first.
