The woofer is an 8" Vifa molded cone with a 2" dustcap and a double-wound voice-coil. Its free-air resonant frequency is
28Hz, and while the sealed woofer enclosure
can be expected to raise that number some-
what, the effect is tempered by the presence of
an additional bass driver in the same enclosure:
an actively driven, rear-firing 10" cone whose
effect on the speaker’s bass system is similar to
that of a passive radiator.
It's similar to a passive radiator. It may not be a actual passive radiator but it is similar to one. That is why I called it a PR. This 10" er has also been called an active acoustic coupler & a fiber-cone “supplemental” woofer, but has never been called a real woofer like the real 8" woofer that is above it and around the front. I used to owned these speakers and never liked them as I thought the bass was to slow and a little sluggish, I also did not care for the over all sound of the whole speaker.
You have to understand, this is just my opinion and all I'm doing is saying I don't like them,don't I have a right to state my view? I just don't care for Vandersteen speakers. If it was my money at $2700.00 I would buy the Eminent Technology LFT-8b speakers for $2500.00 that is what the owners of VPI turntables use at their factory.
