Live vs. Recorded Demo by VMPS at CES

Recommended Posts

Working on some VMPS speakers here and came across this discussion:

Several here have mentioned LvR demos but I don't think this one was

included. I didn't hear it so I have no comment on how it was done.

It doesn't appear that they made the recordings anechoically; if not, it couldn't possibly have worked worth a whit.... :)

But this is on topic here because you guys are planning on staging one like it when you've done your next "mods, tweaks and upgrades to the Classics" project...right?

Now you're sounding like all the AR guys here, LOL!

It was in a very large room and the results would depend on

microphone distance. This is a very complicated subject, and

if you were not there it is really difficult to make any definitive

statements.

I have to tell you Zilch, blanket statements like this come across

as a bit like trolling for a debate.

Nah, we can forgo the debate, and just cut direct to the win for Zilch:

[it was a setup.... :) ]

You consider this to be definitive? The test was not

double blind so that could easily have been what he

thought going into the demo and simply used it as

_his_ excuse for why it sounded recorded in his

opinion.

As I said previously, this is a very complex subject.

Consider the dearth of conflicting opinion.... :D

Score one for Zzzzzzzzz.

I went on VMPS web site. They'd have been crowing about it if the LvR demo had worked well. Didn't even get a mention. Must have bombed. Four ribbon midranges, one ribbon tweeter, five 6 1/2" AS woofers with response down -3db at 70 hz and prices start at $8900. Imagine what they'd charge for a real speaker :) Two photos show two different subwoofers...presumably that costs extra.

The mids and tweeters fire through a long thin vertical slit which is how it achieves wide lateral dispersion. Now that is what diffraction is about. Big and expensive, it reminds me a little of the TOTL Von Schweikert. VMPS also has a rear firing tweeter you can switch in or out. Looks like they couldn't make up their mind what they wanted.
