Twenty-five hertz is below where most people stop hearing and start feeling. It is the frequency band where a film's low rumble sits, where the room itself becomes part of the soundtrack — the approach of something large, the weight under an explosion, the bottom note of a bassline that a TV speaker simply renders as silence. The Sub (Gen 3) reaches all the way down there and holds the note without softening it. In a Delhi flat where the living room does double duty as the home theatre, that is the difference between watching a film and being inside it — and because the low end is coming from a single cabinet on the floor, you get that weight at a volume that keeps the neighbours out of it.
Dual force-cancelling drivers — the reason it stays clean at full output
A subwoofer's worst enemy is its own cabinet. Push a single big driver hard and it kicks the enclosure back the other way, and that energy comes out as buzz, rattle and a smeared, boomy note that has nothing to do with the recording. The Sub (Gen 3) mounts two drivers facing each other so their forces cancel out inside the cabinet — the air moves, the box does not. The result is bass that stays pure and distortion-free even at the top of its 245 W output, with no vibration walking across the floor and no cupboard doors buzzing in sympathy on the other side of the room. That is what lets you actually use the volume you paid for.
A sculptural cabinet you can stand up or lay flat — placement without compromise
The Sub (Gen 3) is built as a piece of furniture: a slim, award-winning silhouette with an open centre and a high-gloss black finish, in a polycarbonate enclosure with a waterproof finish that holds up to Delhi's monsoon humidity and the fine dust that settles on everything through April and May. At 38.9 × 40.1 × 15.8 cm it stands upright beside the TV unit or lies flat and slides under a sofa or console — and because the force-cancelling design means orientation does not affect performance, you place it where the room has space rather than where the acoustics demand. In a compact flat with no dedicated media room, that flexibility is the whole point.

🛠️ What's inside the cabinet
Handing the low frequencies to the Sub frees the speakers it is paired with to concentrate on the mids and highs — dialogue gets clearer, vocals sit forward, and the whole system sounds larger without anything being turned up.
Force-cancelling drivers eliminate cabinet vibration and rattle, so the bass stays tight and defined right up to full output instead of turning into the boom that gives subwoofers a bad name in small rooms.
With the Sub carrying everything below the crossover, the speakers it works with stop straining for low notes and focus on mid and high range — the practical result is clearer, fuller, more detailed sound across the whole system.
A high-quality polycarbonate enclosure with a waterproof finish — the kind of build that shrugs off monsoon humidity, summer dust and years of standing in a living room without warping, dulling or developing a buzz.
It joins the system over Wi-Fi, so there is no thick subwoofer cable to run under a rug or along a skirting board — you decide the position first and the wiring never argues with it.
