Going from Bi wire to Single wire

Yes is it worth removing the back plate on the binding posts and making a semi permanent connection?  Is it difficult to do?

(1) This is a well -travelled road on every forum Inc, including lotsa on  AGON. Here is a sampler in the interests of brevity

(2) The benefits of bi-wire versus single wire is purely system dependent ..... there is no magic silver bullet solution and one size does not fit all .... full stop.

(3) Without prejudice to anything above , I would never undertake to **** around internally in the speaker as your OP suggests, Rather, use single runs to one set of the binding posts with matched jumpers to the other set of binding posts . Then make your assessments .

(4) bi-wire vs singe wire? Per any and all of the above ......here's a  short primer from ad hoc manufacturers....

(A) NORDOST

They highlight the benefits of better quality single runs/jumpers instead of cheap bi-wires. They also highlight the benefits of the diagonal connection array

(B) Even CHORD is leaning toward a single run / jumper array

An older link on their website - now delisted - offered up the following

2. What the two sets of connectors on the back of the speaker do allow you to do though is bi-amp. This means using an amplifier to drive the bass units and another to drive the treble units. This can make a big difference to sound quality, bringing extra definition, control and dynamics. If you choose to do this we would suggest connecting each amplifier with a pair of single wire speaker cables. We believe that this will sound better than using a single bi-wire cable and will be easier to route."

3. "As a general rule, the treble connections are usually reckoned to produce better sound quality than the bass connections. However, in many cases, we find that a diagonal connection produces the most musically coherent sound. To do this, connect the positive (+) speaker cable to the positive treble connection and the negative speaker cable (-) to the negative bass connection. So in effect, the cable is connected diagonally. This is quick, easy and fun to do and the results are easy to hear."

I did try to do a search on the topic and it was more on the benefit of singe vs. bi wire.  I was told that physically going inside the speakers and
connecting the two posts (hi/lo) would be best.  Akg, I'm with you about not messing around with a manufacturer's engineering know how and leaving it alone.  

Vandersteen state a very very clear preference for an external biwire
if you have a good relationship with your dealer you can also test the Nordost claim that better single wire plus jumpers beats equivalent $ biwire set
check the claim with your own ears

Will do thanks.
