Von Schweikert VR4Jr how is it w/o biwire?

The VR4jr does not live up to its potential when used with the data link. At the very least one should use a matching jumper to connect the bass module to the top module. Best performance will be had using double bi-wire (shotgun) with this speaker and the Gen III.
My Gen. III's, (front), are wired with Acoustic Zen Satori Shotgun. My 4jr's, (rear), are wired with Audioquest Types 2 & 4 to very good effect.
Also, both of these speakers perform their best with plenty of power. They like some sauce in front of 'em.

Yes the performance is diminished if you use the datalink. It's even mentioned in the manual. Adding leadshot, biwire (or biamp), and using spikes are a must.

Agree wholeheartedly with the previous posters. Bi-wire is a must, as is lead shot and upgraded spikes. Do all three and you'll have a VERY different speaker from stock.

how to bi-wire if my power amplifier has only 1 set of output connection? can I use 2 different brands of cables and clamp plus-plus and minus -minus on my power amplifier?
most importantly will it damage my power amplifier?

Most do - most biwire cables have 1 connection for the amp end and 2 for the speaker end.

"can I use 2 different brands of cables and clamp plus-plus and minus -minus on my power amplifier?"

Yes

"most importantly will it damage my power amplifier?"

No

Hi,
I need some recommendation from you guys on what is the best cable to use for bass unit for vr4jr bi-wire configuration?
for mid-hi unit I am using the analysis plus solo crystal 8 speaker cables.
hope to hear from you soon.
thank you.

The vr4jr doesn't sounds good when using data link is because the signal has to travel a longer way to reach the tweeter module, bass and treble are not functioning at the same speed.

"the signal has to travel a longer way to reach the tweeter module"

When not bi-wiring the VR4JR, don't connect your cables to the bass cabinet. You should connect the speaker cables to the monitor posts and pass signal to the bass drivers using the datalink and jumpers across the lower posts. This might be why some people see poor results when not bi wiring.

I've had it all four ways and bi amping really is the best thing with these speakers. It adds an astounding depth and authority that I never heard when single amped and single wired.

If you are using a single bi-wire connection, I can teach you another way of hooking up your speakers. these configuration only requires an additional pair of short jumper wires. basically to match the types of bass you desire.
Its a bit difficult to explain here, if you are interestd to know you can forward me your email address and a picture will send to you with the soonest possible.

Double biwire with two pairs - one to the M/T, one to the lower posts of the sub unit. Anything else is inferior.

I got two sets of Bob Crump's (TG audio)speaker cables going and it improved the sound dramatically... Tried Tara labs, Cardas GC and Wireworld to name a few. The TG out performed them pretty easily in my system. Resolution goes up very noticeably when bi-wired. IMO VS should sell these speakers without that Datalink to ensure these get bi-wired. It really does improve them significantly.

good listening
