Interesting. I honestly don't do much orchestral, but it does have very low bass. I listen to much more rock and heavy metal and have found the bass to be satisfying overall, but i do want the Quatro to get better and more bass. I heard the Quatro and 7 mk2's yesterday at Audio Connection as Richard was there visiting. The 3's do go lower, but the Treo has better quality according the to designer of the speakers. If you feel you are getting better quality and more bass in your 3A's, then you are as it's your ears. jafant, that's fair that you discount both speakers, but there are so many folks who love them as I heard folks talking about switching to them yesterday. That's why other's can sell their wares also.
The one thing I will say is that Vandersteen is about to come to market with a new sub that will only be sold in pairs and will ROCK. As long as you have a speaker that goes down to the high 30's you can use it without losing coherency as the bass needs to overlap a full octave to achieve that. That's why it's so difficult for anyone to properly mate a sub with a non full range type of speaker. it is pretty interesting stuff how he mates the sub's amp with whatever amp you are using to keep the same sound signature. Just thought I'd share and this thread is a good one to throw it out in.
