More cone, more output — and deeper 

A bigger 12″ cone moves more air, so it plays louder and reaches lower than the 10″. 

Output from a sub comes down to how much air the cone moves, and a 12″ cone has a lot more of it — 483 cm² here, against roughly 300 for a 10″. It’s the same 15 mm of travel, but each stroke shifts more air, so you get more output for the same excursion. The bigger cone also resonates lower, which is why this one reaches down to 28 Hz where the 10″ stops at 30. If you want the bass to go deeper and hit harder, and you have room for a 12″, this is the one. 

A serious motor 

A big double-stacked motor keeps a heavy cone under tight control. 

Behind the cone is a double-stacked ferrite motor — two 50-ounce magnets — developing a 17.8 T·m force factor, even stronger than the 10″’s. It needs to be: a 12″ cone is a heavier thing to move, and a strong motor is what grips it tightly enough to start and stop the bass cleanly rather than letting it boom on after the signal. It also handles the current from 800 watts without losing its composure. 

Long-throw, kept linear 

A tall coil and twin spiders keep the big cone travelling straight. 

The voice coil is wound 40 mm tall, so it stays engaged in the magnetic gap right through 15 mm of travel each way, and two spiders — not one — hold the cone dead straight instead of letting it rock as it reaches the ends of its stroke. On a large cone moving this far, that control is the difference between clean, deep output and audible distortion at volume. 

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 high-current 1-ohm option there for the amplifiers built to exploit it. 

Big output, and the box it wants 

It rewards a proper sealed enclosure with deep, controlled bass. 

Its equivalent compliance volume (Vas) is 33.6 litres — larger than the 10″’s, as a bigger cone will be — so it wants a little more box to work in. It’s still happy sealed, which keeps things compact and controlled, and a sealed enclosure sized for it gives you the tight, deep bass this driver is built for. Plan the box around the driver rather than around the space you happen to have spare, and it pays you back. 

The cone, and the build 

A stiff cone and a proper chassis stand up to the power. 

The cone is fibreglass cloth — stiff and light, so it holds its shape under the forces that 800 watts and 15 mm of travel put through it, rather than flexing and distorting. A foam surround gives the compliance for the long throw, the coil sits on an aluminium former that carries heat away from the windings, and it all mounts on a steel basket with an injection-moulded dust cap. It needs 172 mm of depth and a 280 mm cut-out — a full-size 12″ that wants a proper install to do its thing.
