I am Not hurting anything right ??


I have a pair of Sonus Faber Concertinos that have bi wire posts. I have Bi wire Cable but have told NOT to Bi wire these Speakers. so I left the jumpers on the back and pluged in the cable as normal(standard bi wire configuration). Speakers sound great. But am I running any risk as to damaging the speakers?

Best Regards

I was told by the distributor that the biwire posts were added due to market pressure. From what I understand the manufacturer does not recommend biwiring. ( Their new models can not be bi wired.) I guess I need to reterminate my cables however I thought with the jumpers+the biwire cable I was essentialy doing the same thing.

Thanks
No harm to leaving the jumpers in (unless as some people say, you will benefit from replacing them with a small length of speaker wire). I doubt seriously that you need to reterminate your cables. If your speakers are bi-wireable (because thats what the market wants), it cant hurt to take the jumpers out and use them that way. You may even find you like them better bi-wired. But if you prefer the sound with the jumpers in and all four cable ends attached (belts and suspenders), use them that way and dont worry about it.
In response to Sdcampbell and KennyT, as a matter of fact you DON'T feed a full range signal to both terminals in a bi-wire configuration. Through some unexplained phenomenon (I'm being serious), the crossovers somehow limit the frequencies being transmitted through the cable. The effects have been measured, it's a interesting occurance. The only frequency being delivered at the same level to both terminals is the frequency point between the crossovers between the terminals themselves.
In response to your question, you are not hurting your speakers in the current setup, but you might be hurting your amplifier. Your amp sends out power over two cables to the + terminal, and the wire is shorted out when it gets there, its like connecting two wires together at the end. Could cause some type of mismatch or something if the wires are not exactly the same or whatever. Not a big risk so don't worry too much.
Try reading Jon Risch's website regarding the "technicalese" on bi-wiring.

As to bi-wiring feeding the same signal to both sets of terminals, that is not necessarily so. On a speaker that is TRULY designed to be bi-wired, the two sections are completely independent of each other. Using the factory supplied jumpers simply ties the whole circuit together. Once the jumpers are removed, you now have two seperate frequency selective paths for the signal to take. While this is the type of "bi-wiring" that MAY result in sonic benefits, it would be negated by using an "all in one" type of bi-wired speaker cable. You would literally need a seperate run of cables for the lows and a seperate run for the highs to achieve optimum results.

As to speakers that were designed for bi-wiring as an afterthought or as a marketing gimmick, you might not gain anything other than the lower resistance of using more wire as a conductor. In itself, this is not a bad thing but hardly worth the extra money. Sean
