Vandersteen 4

Does anyone know if the drivers are the same on the 4 as on the 5 ?
Sounds like this was their first atempt at the push/pull sub.
I wonder if its the same except requiring a seperate amp unlike the 5's built in ?

Though Richard Vandersteen's basic design parameters have remained consistent, a lot of time time elapsed between the discontinuation of the 4's and the implementation of the 5's and the Quatros.

Just got a pair of Vandersteen Model 4's. Removed the bottom and top end caps and replaced them with custom made caps made from ebony macassar wood.They now have a Sonus Faber look, well sort of. I have 2 ARC classic 120's on top and a updated (Sept.20,2011),Eagle7A on the bottom. Looking for speaker wire. I prefer Audioquest but...

Interesting in that I heard Vinh's (Hi Vinh) and there was also a local audiophile in my area that had a pair. It was my introduction into the hi-end. His were in a VERY large great room and I would expect that this would be a minimum requirement. He drove them with Perreaux monoblock amps from New Zealand. While I certainly can't give specifics as this was more than 25 years ago I can say that the bass these speakers produced were most impressive to me at the time. This impression lasted and was apparent with each successive time I heard his system. I'm sure the size and irregular shape of his room helped. Shortly after that experience I ended up with a pair of 2C's. I believe they retailed for 4K back then. It seems to me that there were issues with this design unlike any of the other Vandersteen models. Maybe someone can fill in the details?

Joshc, it sounds like you decided to keep your 3A Sigs. If additional bass was a reason to ask about the 4s, why not now consider a pair of Vandersteen subs? That would be far easier to implement and likely a better overall result.
