  We generalize quintom to include the tachyonic kinetic term along with the
classical one. For such a model we obtain the expressions for energy density
and pressure. For the spatially flat, homogeneous and isotropic Universe with
Friedmann-Robertson-Walker metric of 4-space we derive the equations of motion
for the fields. We discuss in detail the reconstruction of the scalar fields
potential $U(\phi,\xi)$. Such a reconstruction cannot be done unambiguously, so
we consider 3 simplest forms of $U(\phi,\xi)$: the product of $\Phi(\phi)$ and
$\Xi(\xi)$, the sum of $\Phi(\phi)$ and $\Xi(\xi)$ and this sum to the
$\kappa$th power.
