what does ohms and db mean?

[jomari]

correct.

there are also other factors to consider, most of my colleagues would consider

source (receivers, pre/pro, tubes et al)
media (may it be in hd or not, turntables)
connectivity (speaker wiring, digital or analog, power amplification/cleaning)
and
ACOUSTICS (reverbations, echoing, et al)

i mention acoustics in all caps due to a number of people leave this as 10% of what their home theater should focus on. when my colleagues would mention that the room acoustics also plays a significant amount to improving the sound and color of your media room, even to boast it at a good 80% improvement. in the real world, we cant have acoustic panels, basstraps replacing our wifeys beautiful picture, or move the big useless vase in the corner to accomodate our needs.
