What the maker puts in writing
All five bullets, in full:
- “PREMIUM TOWER SPEAKER PAIR - This package includes (2) SVS Ultra Evolution Titan 3 Way Tower Speakers in Piano Gloss White”
- “ACOUSTICALLY CENTERED CABINET ARCHITECTURE - The cureved front baffle aligns all drivers to ensure each driver reaches your ears at the exact same instant”
- “DIAMOND COATED ALUMINUM DOME TWEETER - The Vapor Deposition process applies a layer of diamond carbon to the aluminum dome tweeters to improve rigidity and acoustic properties”
- “QUAD 6.5 Inch GLASS-FIBER WOOFERS IN FORCE BALANCED ARRAY - The dual opposing woofers on the top and bottom of the cabinet render low frequency response while addressing room modes”
- “ATTENTION TO DETAIL - The separate, acoustically tuned, internal champers for the woofers and drivers optimize separate and eliminate potential for cabinet resonances”
Three typographical errors in five bullets: “cureved”, “champers”, and a final sentence — “optimize separate and eliminate” — that does not parse.
The force-balanced array is the real engineering
Quad 6.5 inch glass-fiber woofers in force balanced array - the dual opposing woofers on the top and bottom of the cabinet render low frequency response while addressing room modes.
Two separate ideas, both sound.
Dual opposing means two drivers mounted on opposite faces and driven in phase: as both push outward, the air moves and their reaction forces cancel inside the cabinet.
That matters because a single large woofer pushing air forward pushes the box backward with equal force. The cabinet walks, rattles the floor, buzzes the furniture under it, and radiates sound of its own that smears what the driver is doing. Canceling the force removes all of that.
And top and bottom addresses something else. Bass sources at two different heights excite a room’s vertical standing waves differently from a single source — so the peaks and nulls from one partly fill the other’s, and the response across the listening position smooths out.
Four 6.5-inch cones also give the largest total radiating area on this shelf: roughly 2.4 times a pair of 6.5-inch woofers, and about 16 percent more than the Fluance Signature’s dual 8-inch drivers.
The curved baffle is the right answer to a real problem
The curved front baffle aligns all drivers to ensure each driver reaches your ears at the exact same instant.
A tweeter’s voice coil, a midrange’s and a woofer’s all sit at different depths behind a flat front panel. So sound from one has further to travel than another.
Around the crossover frequencies, where two drivers are both producing sound, that path difference means their contributions arrive out of step and partly cancel — leaving a dip in the response and smearing the sharp leading edge of a transient.
The usual fix is electrical: delay the nearer driver inside the crossover, which costs phase accuracy elsewhere in the band.
Curving the baffle moves the drivers physically so the distances match. It is expensive to build and it is the correct solution.
Two other listings address baffle behavior differently: Fluance’s Signature publishes a 1.4 inch thick baffle with chamfered edges to cut diffraction, and KEF publishes “Shadow Flare geometry”.
Separate internal chambers, which is worth the mention
Separate, acoustically tuned, internal chambers for the woofers and [the other] drivers.
In a single-chamber three-way tower, the woofers’ pressure acts on the back of the midrange cone as well as its own. A midrange driver trying to track detail while being pushed around by a 40 Hz pressure wave does so less well.
Isolating it in its own sealed chamber removes that entirely — and lets each chamber be tuned for its own driver.
Nothing else on this shelf publishes it. Fluance’s Ai81 publishes internal bracing, which addresses panel flex rather than inter-driver pressure.
The diamond coating, and what it is for
The Vapor Deposition process applies a layer of diamond carbon to the aluminum dome tweeters to improve rigidity.
A tweeter dome has to stay rigid while reversing direction thousands of times a second. Once it begins to flex rather than move as one piece, it breaks up and adds frequencies that were never in the signal — and where that happens sets the top of its useful range.
You raise stiffness either by making the dome thicker, which adds mass and slows it, or by coating it — adding rigidity for almost no weight. Diamond-like carbon is about the stiffest coating available, and vapor deposition is how it is applied as a thin film.
The domes on this shelf: silk (Dayton, Rockville, Polk) · aluminum (NHT) · diamond-coated aluminum (this) · inverted aluminum-magnesium M-profile (Focal) · Uni-Q with MAT (KEF) · and both Fluances naming neodymium, which is the magnet rather than the dome.
But four thousand dollars publishes no measurement at all
No frequency response. No sensitivity. No impedance. No power handling. No weight.
Five figures absent, on the most expensive product here.
The comparison is unavoidable. KEF’s Q11 Meta at $1,249.99 each publishes 37 Hz at −6 dB, in-room bass to 26 Hz, 89 dB sensitivity, a 15–225 W amplifier range and 49.6 lb (22.5 kg). The Rockville at $119.95 a pair publishes 125 W RMS and 500 W peak, 8 ohm impedance and 33 lb (15 kg).
So the two opposite ends of this shelf both tell you more than the top of it.
What SVS gives instead is four genuine engineering claims — the force-balanced array, the curved baffle, the separate chambers, the diamond coating — each addressing a real mechanism, and none of them quantified.
No connector published either, where both Daytons and the Rockville publish gold-plated binding posts. No enclosure type — sealed or ported — where five listings state theirs and each explains why.
439 × 249 × 1182 mm is published: the widest cabinet on this shelf, which the top-and-bottom woofer arrangement explains.
And it is a pair
This package includes (2) SVS Ultra Evolution Titan.
Worth confirming, because three listings here are per speaker. The real pair prices:
Rockville $119.95 · Dayton T65 $229.98 · Polk ~$498 · Fluance Ai81 $599.98 (powered) · Energy $799.98 · Fluance Signature $799.99 · NHT $1,499.98 · Focal $1,993.90 · KEF $2,499.98 · this $3,998
