I tried both and heard very little difference but settled on the 4ohm one. For my space, though, the non-ported 802 d3 just didn’t pack a low end punch. I tried integrating a sub but didn’t like that either. I actually use the 805d3 for my home theater (paired with a Theta amp) and an SVS-SB16 which wound great. The SB16 really fills the space.
