Deep banging internal sounds suck! Can be a few different things (loose driveplate, cracked driveplate, wristpin) I say these cause you said it is intermittent if it was rod or crank related they would be constant.  Do a brake torque in forward and reverse and listen to the noise to see how it changes. Not a hard brake tq just raise the rpm to about 2500 in D and R.
