Well what do you consider "head banging levels"??? By head banging levels do you mean concert loud?
Hmmm okay well considering you don't recommend pioneer subs, are there any you would recommend? If I got the pioneers but not the sub I would get the 5.0 setup. A sub that blends well with them would be ideal since quality blending and a good soundstage seems very important. Obviously I dont want a sub that stands out from the speakers.
When I say head-banging, I mean below room shaking levels, also below
club-house, concert and theater levels.
They do and will play loud - For most people they will play louder/above
the levels, that would be average for them. Some speakers can/will play
louder - however they do not sound as good, and can become annoying.
As I stated before > the Pioneers are not a wimp, and have good drivers.
They do have good bass > some speakers have more bass - however,
more bass does not guarantee all around good quality. > The Pioneer
is more natural and less artificial than a lot of towers that cost more.
The Pioneer's do not have a boom, boomy and mushy character. They
can take some power and it is not easy to make them burp.
For a tight budget and to help extend, blend and balance the bass >>
