Vandersteens-- Removing M5-HPs for a Digital Xover?


Hi. Quick survey of people that have removed the M5-HP when using a processor/preamp that can do the Xover internally and how much of a sonic difference there was. I guess there is just something comforting about having the physical Xover in-line when the manual (I have Quatros) talks of all the driver damage that will occur if they are used without a Xover. I just upgraded my pre/pro to a Theta Casablanca that can do it internally. I would assume that there would be some kind of difference due to eliminating the parts inside the M5 and the electric change of having dissimilar metals between my interconnects and the pigtails of the M5s. I know that hearing it is the only proof but wanted to see others’ opinions. Thanks.

Nice stack of gear, and I don’t even know what else is in it.
It is odd running Vandys in a surround system. There are at least 2 of us, but my speakers and amps are not at your level and I have Lyngdorf rather than a Theta… But I think the concept is the same..

I would probably tell the pre processor it cuts off at 40, 60, 80 (I dunno, just dick around with it)… And then it will boost whatever is too low up, and you will not hear anything wrong at the frequencies which we are not overly sensitive to.

But I have not completed my set up.
Alternatively there is Vandy forum.

Vandersteens actually make really great surround systems due to their spaciousness.  You can honestly just run movies two-channel, and they sound great.  Also, their surrounds (VSMs) are made to be wall-mounted and look very sleek when done so.

It was astounding how well the TV sounded just going to 2.0.

I have 2 pairs of pre-loved VSMs coming, or maybe they arrived.
I’ll use one for the LR/RR of the 5.x.x.
I am thinking about using the other pair for a 5.x.2 or 5.x.4 Atmos.

And also preloved VCC-5, which my friend picked up yesterday from DHL/FedEx.
 

To your comment about the Xover frequency, though, it HAS to be correct on any subs or else it will damage them.  Just so you don't ever do that if you get some.  Other passive models can be toyed with, sure.

What do you mean damage them?
Do you mean powered subs in the quatrros?

Are you running a 2.0 system, as well or is it exclusively HT?
If it was 2.0, then the XO in the cable to the amp rolls off the lows, and they are built back up in the subwoofer section.
I suppose if you are not running those in-line XOs, then you would roll off the main speakers t the 6dB/octave at the 100 Hz point.

With my AVR I tell them how low that the LF and RF go… if the Theta did that, then you may want to say that they only go down to say 40 Hz… Then the loud thumps in movies would not be trying to extend them down to 20Hz.

I would assume that you would be using a separate LFE sub in the 10-40 range (or higher)?
And relieving the speakers from the brunt of it for movies should not overly stress them.

If there was a bypass for 2.0, then Quatrros would so what they are supposed to do for music, which is not mixed as deep/hard for music, unless it is some rap or techno… or whatever it is called.

I mostly trying to understand, so take ^these statements^ as more like ideas and discussion, then gospel facts.

This is like saying if i disconnect the Brakes in my car how many of you fellows will still have their family jewels left and are they still in decent working condition.

 

I try not to put my ‘alls on the line… in case they still work ;)

By the way I heard very good things about you and your shop.

 

Johnny - I really doubt that any "charged capacitor" internal crossover networks can compare to an active crossover using multi-amps. Vandersteen has some of the best, but JBL started this 60 - 70 years ago. Unless you’ve tried eliminating passive crossover components between the amplifier outputs and the drivers (just plain copper wire) you will not know the improvements. All the best.

I pretty much agree, but most users have big mono blocks and are wedded to the passive XOs.

But at least there are two of use in a small boat.

It would be interesting to hear both approaches with the same drivers/boxes. I have been toying with that idea for some older 2Cs.

I asked this legend race car drover once about braking technique and going fast.
He said, “Brakes do not speed one up, so it is best to stay off of them.”
(It’s sort of true once I watched closely at his technique… he would just brush them to transfer some weight.)

 

@holmz --Congrats on the VCC-5.  I haven't been able to find one in black in some time.

If I resock the VCC-5, I’ll save the sock for you.
I may also end up pulling the top and bottom of it, so I can shove it into a cabinet.

I actually started on the table for it, so the top is 1/2 done.
