Vandersteen 4

There was actually a Model 4 at one time. No, I don't believe it would be a step up from 3A Signatures.

Mofi- there actually was a Model 4 and a 4a, a predecessor to the Model 5. It was kind of like a Model 3 w 2, 12" (powered, I think) sub-woofers built-in. You see them here maybe once every 5 years or so. I've never heard them, but I almost bought a pair on a whim a few years ago. They are BIG and HEAVY, IIRC. Looked like a Model 3 on steroids.

Thanks! I have never heard of the Model 4. Most companies won't use the number 4 as a model number. I have been corrected...

So why is number 4 bad luck but twice 4 or number 8 is considered a good luck number.

Wouldn't it be twice the bad luck? Just sayin'

I used to own the model 4A (see pic on this link):

It was the biggest Vandys in the 90s, 5-way, tri-wireable, with an external active crossover.
See more info on it here:

Its sound is similar to the old Vandy design - balanced, if a little reticent. I bi-wired them with Transcendent Sound SC-150 on top and a pair of Odyssey Stratos at the bottom.
They sounded neutral for all kinds of music but not as dynamic as the new Vandy models.
I finally sold them because they were too big even for my great room. You will need a big room for them to sound good.
