Hi Keith,
Yes. The HD-70 has a fixed offset
of 36% . So for a 100" diagonal ,from the centre of the lens you will have a image offset
of 17.64".
HD-65 is a new model . worth taking a look
if you have uncontrolled light ambiance in your set up. Besides ISF calibration
will make your Home theater "Picture Perfect".
Regards
Rajesh
