Yes, I think the aeon-i needs a sub. I plan on adding that to mine in the near future. It's interesting though that it also seems to depend on the recording I'm listening to. John lee Hooker sounds amazing, whereas bass notes from some beastie boys albums seems a bit light.rampage60 said:Might add a sub. Looking @ "Velodyne SPL-1000 R " $1299. What are your thoughts and if you think thw Aeon needs a sub. Thanks for you input!
