The BA10D2S-V3 is the 10″ in the BlackAir flat series — the bigger sibling of the flat 8″, and the choice when you want more output and deeper bass but still have almost no depth to give. It fits in 79 mm, and it’s a proper 10″ underneath: a full 346 cm² cone, 300 watts, and a dual 2-ohm voice coil that wires to any amp.
The extra size over the 8″ does what extra size always does on a sub — it moves more air and reaches lower, down to 31 Hz. It just does it in a frame slim enough for the installs a normal 10″ won’t go near.
It’s a flat sub, with the honest trade-offs that come with that. But if you’ve got a shallow space and want the most bass you can get out of it, this is the one.

A bigger flat sub
A full 10″ cone in 79 mm of depth moves more air than the flat 8″ — and still fits shallow.
Cone area is what makes a sub loud, and stepping up from the flat 8″ to this 10″ adds a lot of it — 346 cm² against 214. That’s more air moved for the same effort, so more output, and it comes in a frame that still needs only 79 mm behind the baffle. You get most of the fit advantage of a flat sub, with a meaningful step up in the amount of bass it can produce.
It reaches lower
The larger cone resonates lower, so it digs deeper than the flat 8″.
A bigger cone has a lower natural resonance, and this one sits at 36 Hz with a stated response down to 31 Hz — noticeably deeper than the flat 8″. In a car, that lower reach is the difference between bass you hear and bass you feel in the seat. It’s still a flat sub; it’s just the flat sub that goes low.
Wire it to any amp
A dual 2-ohm voice coil matches whatever amplifier you run.
Two 2-ohm coils give you a 1-ohm mono load in parallel, a 4-ohm mono load in series, or independent connection across two channels — so it suits just about any monoblock or bridged amp, with the 1-ohm option there for the current-hungry ones.
A coil built for the power
A four-layer copper coil on an aluminium former handles 300 watts and the heat that comes with it.
The voice coil is wound in four layers of copper on a 2.4-inch aluminium former — a larger coil than the flat 8″, for the extra power handling. The four layers give the motor a firm grip on the cone, and the aluminium former pulls heat out of the windings so it doesn’t compress under sustained power. It’s the same coil-and-former approach that runs through the BlackAir subs, scaled to suit this driver.
Small box or none, and how it fits
A high total Q means it works in a small sealed box — or free-air.
Its total Q is on the high side (0.76), which makes it flexible about enclosures: it’s happy in a small sealed box, and it’ll also run free-air or infinite-baffle, firing into the boot from a shallow mount with no cabinet at all — handy when even a small box is a stretch. We’ll be honest that a flat 10″ won’t hit like a full-depth, long-throw sub; its 7.1 mm of travel and 82.8 dB sensitivity are modest by design. But for the depth it saves, it gives a lot back. It drops into a 232 mm cut-out at 79 mm deep, on a steel basket with push terminals.
