Arv Posted March 24, 2020 Share Posted March 24, 2020 (edited) Been experimenting lately with my setup and was keen to hear people’s thoughts on diamond wiring bi-wire compatible speakers. I’ve got a pair of B&W cm8s2 and tellurium q black 2 cables and jumpers. I came across the following website which recommended to connect speakers in a diamond pattern https://www.pursuitperfectsystem.com/are-you-diamond-wiring-your-speakers.html Essentially this means to connect your positive to the HF binding post and negative to the LF binding post and use the jumpers to complete the connection. I have to admit that after a couple of days of listening I did find this change made a positive difference, which I’m finding hard to explain... other than I much prefer it this way... not sure if it’s my mind playing tricks on me, but was keen to see if other members have tried diamond wiring and what experiences they’ve had! On a side note, hope everyone is taking care and staying safe at this time! Edited March 24, 2020 by Arv Typo Link to comment Share on other sites More sharing options...
jeromelang Posted March 24, 2020 Share Posted March 24, 2020 yes, cable jumpers are sonically directional alright.... Link to comment Share on other sites More sharing options...
jeromelang Posted March 24, 2020 Share Posted March 24, 2020 at home, i've always run 2 pairs of speaker cables to my speakers. at work, quite a few times, ive had to decide between the upper freq and lower freq terminals. the lower freq inputs have always sounded better on many pair of speakers i've tried.

That isn't quite what the OP is saying. The 'diamond' method uses one input each of the LF and HF terminals. I am by no means an objectivist, but it would be helpful if the OP could in some way describe the improvement he has heard. Link to comment Share on other sites More sharing options...

On a side note, hope everyone is taking care and staying safe at this time! I get theory behind it, but at the risk of sounding obvious I'd say consult your speaker manual. Most electrical circuits, including those in your speakers, are designed to produce optimum results with the current flowing through them in a particular direction. For example, every B&W manual I looked at shows the speaker cables from the amp plugged into the bottom set of terminals on the speaker. Then add your jumpers. The manual doesn't say you have to connect it this way, but it recommends you do to get the best performance. On the other hand, the manual on my Revels recommend the speaker cables go from the amp to the top set of speaker terminals and then add your jumpers. Neither is wrong, it is simply based upon how the manufacturer has designed their speaker to produce optimal performance. FWIW, I tried your diamond wiring. No, nada, nope, nup. Midrange was incoherent, messy and muddled. 3D imaging was all buty lost. Timing went right out the window. There may, or may not, be a set of speakers out there that diamond wiring may suit, but it certainly isn't mine. That said, I've yet to find a speaker manual that recommends the use of IsoAcoustic GAIAs either. And we all know what a difference they can make.

I have not tried this diamond connection method. So I can't say if it is better or not. I'll keep an open mind regarding this. But between the LF and HF terminals, input into the LF terminals have always sound better with all the speakers that I have tried. What I heard was always consistent - more neutral tonal balance, better coherence from top to bottom frequencies, better all-round musicality.

I’ve attached a picture below. Yes, as Bronal pointed out I meant wiring the positive from the amplifier to the positive HF terminal and negative from the amplifier to the negative LF terminal and use the jumper cables to connect the negative and positive LF and HF accordingly. I have included a picture of what I mean below. Improvement wise, for my ears I found that I was able to discern ‘detail’ from familiar tracks that wasn’t previously. Separation also improved and the bass firmed up. However, I will keep experimenting to see what is best. I am in the process of purchasing new speaker able as well! 10 hours ago, Happy Sacks said: I get theory behind it, but at the risk of sounding obvious I'd say consult your speaker manual.

Double checked my manual and it does show to wire to the LF terminals and use either the metal jumper strips or jumper cables to the HF.

Colin Rutter Posted March 26, 2020 Share Posted March 26, 2020 It seems difficult to describe the physics behind the wiring method. Perhaps in an alternate universe it is explicable. Just a note that might surprise. Electrons do not flow through a conductor. Link to comment Share on other sites More sharing options...
