Alright, have settled this in my bedroom where they may have found a long term residence. After trimming the highs by -2dB (switch in the back of the speakers) this is what I get in my bedroom.
They get brighter and boomier in my room perhaps due to it being small. But not too bad IMO after the trimming adjustment:
Here are JBL305s measurements from nonaudiophile for comparison purposes:
Now what I needs is a subs. Thinking about HSU. Perhaps just another Pioneer since this is on a second floor and furniture resonates and starts introducing distortion that I know is not coming from the speakers.
As far as the boominess, I could partially block the ports to reduce it, but so far it doesn't bother me much. Maybe later.
