Sorry, I'm a novice to AV. Can somoene please explain some points to me? 1. What do they mean when they say "bright sound" and "colorisation"? eg they say "the sound from this speaker is brighter than the sound from that one"? 2. What do they mean by "tight" bass? Or "this tightens the bass" ? 3. What's the difference betweent he job of the bass channel (port hole) and the bass bin? Whi do some speakers have the port hole at the back, and some have it at the front? Is there a situation when you'd opt for one or the other? 4. When you put foam plugs into the port hole of a speaker to reduce boominess, does it mean we're losing some of the bass we paid for? Will turning up the bass in the amp bring back the bass absorbed by the foam plug, and will it still be less boomy? Sorry again for being such a novice, but I hope someone can clarify these points.
