Von scheikert VR4jr what are you using ?

Blindjim,
Thanks for your reply. I tried an experiment tonight, just hooking up cables to the upper pair on the woofer module - No sound.
I don't think that you are doing anything by hooking up cables to these posts. They're just not connected to any drivers, I believe.
Can someone please prove me right or wrong?
BTW, I walked into my room tonight to find one of my M/T modules on the floor! Only minor damage - Must have been my dog tangled in the cables. BooHoo

(Long - sorry but here goes) I drive mine w/ Channel Islands D-200s. I actually bought my VR4JRs from Dusty at CIAudio - I think he said that they were the same ones used to help voice the D200s.
Maybe a diversion here, but I must tell you (all)-
I was initially disappointed in the sound of this combo - (JRs came broken in, and amps were reviewer units returned to CIA, lead shot added) flabby overblown bass, no sense of immediacy, snare drums lacked any snap - Just dull and bloated. BUT NO MORE!
I have mine on a suspended wood floor. I placed a 6' 4x4 brace under the middle of the room, and OMIGOD did the sound improve (the look of disbelief on my wife's face was priceless). So if this made that much of a difference, I had to try more. So now I have 2 12' 4x4s w/ 4 support columns supporting the floor - Each floor joist (they run across room side to side) is anchored to a 4x4 in two places with pairs of angle irons, in case joist doesn't touch 4x4. Not done yet - ran bead of silicone between each joist and the flooring above it. Absolutely transformed the sound of the system. There is no amount of cables, equipment, EQ, anything that could have made this level of improvment. I cannot express the extent of this transformation, from the bass all the way up.
One last tweak - The floor spikes are 16.5" apart - This allows the spikes to sit directly on the joists, directly above two support columns.
I did not notice this problem, pre-bracing, w/ my B&W CDM7NTs - I think the JRs put so much energy into the floor that this becomes a major component of the ultimate sound.

Hope that this helps someone to extract the maximum from these speakers.

Blindjim,
Are you saying that you have cables hooked up the all 3 pairs of posts on each speaker?
I find the manual very poorly written as far as wiring goes, especially considering the numerous options.
I think the upper set on the bass module is only for connection to the data link. So that if biwiring, you only would connect to the lowest pair on the bass module and the pair on the M/T module, without using the jumper. Is this correct?
Thanks

Blindjim,
I just got off the phone with VonSchweikert, and they confirmed my previous post, in that:
1) The upper pair of posts on the woofer module are ONLY connected to the datalink port on the woofer module. They are not connected to any drivers UNLESS you use the jumpers (to connect to the woofers) or the datalink or jumper cables(to connect to the midrange and tweeter.
2) There is no need to ever connect speaker cables to all three pairs of binding posts, since only two of the pairs are connected to drivers.
3) The preferred way to biwire the speakers is to connect cables to the posts on the upper mid/tweeter module and only the lower pair of posts on the woofer module, without any jumpers or datalink.
4) When one connects speaker cables only to the upper posts on the woofer module, without using jumpers, there will be no sound since there are no speakers connected to these posts.
5) VonSchweikert, too, sees VR4JRs set up at dealers with cables connected to all three pairs of binding posts, and they are shocked by it and correct this immediately.

That's the word from the factory, and they admit that the manual could be a little clearer and that some users are confused about the right way to hook 'em up.

Blindjim,
"If there is an internal connection of the two bass module drivers... Why then, is there a brass plate on the outside of the bass module ‘apparently’ connecting those two drivers?" Especially if they are hooked up on the inside. I would think the brass plates on the outside supurfulus, or at the very lezst redundant. Then there's the question,"Why are they there if not to connect two different drivers?"

The two bass module drivers are only connected to the lower binding posts. The brass plate is used to transfer the signal between the lower posts (and therefore both woofers)and the upper posts which connect to the datalink only. That's why the upper posts on the bass module are labelled "Midrange/Tweeter input".

I agree that the brass plates on most speakers strap the woofer to the midrange/tweeter to allow for single wiring, but in the VSRs case this isn't so. (Well, kinda so - it will allow single wiring IF the datalink is connected).

Yeah, there are a bunch of ways to hook these guys up. Perhaps the set of cables you have going to the "Midrange/Tweeter input" are changing what your amp "sees", but I don't think so. Maybe you'll have luck in attaching both wires to the lowest pair, if you're using spades.

I think I see why you get better performance having the woofers driven directly by cables than by the straps with the cables hooked to the "Midrange/tweeter input".

All the best...

Jdodmead,
No definitely do not use the jumper plates. As long as you are biwiring to the lowest posts on the woofer cabinet and the posts on the mid/tweeter cabinet, you are doing what VSR wants.

The "top woofer" is not connected in any way to the upper posts on the woofer cabinet. Try it and see!

VSR says the concept of the datalink is so that, temporarily, a user may use a single run of speaker cable connected preferably to the mid/tweeter cabinet, through the datalink so the signal exits out the upper posts on the woofer cabinet, and then through the jumper plates to the lower posts, which connect to both woofers.
Jeesh, I'd rather save a few $$$ and do away with the datalink and the unused posts!
