Doesn't a CD player do this when it converts the 1s and 0s on the CD to an analog audio signal?

Not really, no.

The VTF-3 Mk 2 is at least as musical as the VTF-2 Mk 2

Well, at least Dr. Hsu (what is his PhD in anyway? I feel like a real prat calling a guy that puts drivers into cabinets Doctor. Reminds me of a stoner rock or country-fried rock band) made a subjective analysis. "Musical" could mean anything and is very non-commital. One man's "musical" is another man's "Irving."

Funny thing is SVS said the same thing. a 12inch can rock just as good and just as fast and tight as a 10inch.

Now this I would like some clarification on. There is a certain amount of inertia inherent in a driver's movement - the more mass a driver carries, the harder it is to "turn it around" as it goes from push to pull and vice versa. This is why midrange drivers are smaller than woofers, and tweeters are smallest of all... the smaller a driver, the easier it is for it to push and pull at a higher frequency.

Now does SVS use a lighter - but yet as rigid - material for their 12" cones? If so, why not use it for the 10"s as well? And if not, how exactly do they make a 12" as fast and tight as a 10"?

Well, I'm pretty late to the party with this question, considering the fact that you have already bought your new sub, but in relation to;
"It's not so much the floor space that the wife doesn't like, it's the height of the cylinder that she doesn't like. "
I thought that you could lay those SVS down on their sides.
Was that not an option behind the couch?

Unless I'm mistaken he is a MIT grad and has a Ph.D. in engineering.

As for your other questions, ask SVS and HSU. These guys answer questions just as fast as Axiom does and I'm sure they would be willing to break it down as to why a 12inch driver is as musical as a 10inch driver.

First I have heard of this. I can't say I would have done it however. From everything I have read, my PC-Ultra was built to be upright.

Yes...you can lay the Ultra on its side, it just takes up much more floorspace that way.

Dr. Hsu, to be more specific, I believe has recieved his Phd. in civil engineering from MIT.

Yes, i just Googled Dr. Poh Ser Hsu. Nothing directly states it's a doctorate, but he does hold a catskin in Civil Engineering from MIT. So he can build subwoofers and bridges!

Here you go Bren.....from a google.

I think the bottom line is technically that is correct, but in the end (the sound that reaches the human ear and then processed by the brain) it just gets to be very hard to tell the difference. Esp since volume differences, freq response etc change the perceved result.

i just like to say when people get technical about subs amps speakers it just takes the fun out of the whole ordeal(Lol). if its a bigger driver or a smaller one i could care less as long as it sounds good. i might have to go get a phd just to understand half the stuff you guys are talken about.
