Speaker wire vibration control

So, I was playing some music the other night and reached down to check the connecton to the binding posts. I'm biwiring with spade connectors on the highs and bananas on the lows.

The bananas connected to the speaker end were vibrating to the music when I touched them, as was the back of the speaker cabinet. I decided to try a little vibration control: I wrapped the body of each banana with 5-6 turns of teflon gas pipe tape (the yellow, thicker stuff), then wrapped over that with some 3M micropore tape used in medical settings (around 7-8 turns). Next I took two pieces of polyethylene pipe insulation foam and wedged it between the bananas. I did the speaker end on both sets of bananas as well as the amp end.

Turned the amp back on and started playing tunes. The improvement was immediately obvious, even to my wife who's fairly immune to my audio hobby :lol:

The soundstage expanded horizontally another foot or two on each side. Better resolution of complex passages in which alot of instruments are playing at once, or there are multiple background singers. Instruments sound more full with slightly better attack and decay; bass sounds more defined and full, overall the speakers seem to disappear a little more with sounds more in the room rather than emanating from two boxes 9 feet apart.

None of the qualities above were missing before instituting this tweak, it merely enhanced them. When I realized things were sounding better I was curious if I had completely eliminated the vibrations in the connectors, so I went back to touch them during a loud passage. They were still there but maybe 1/2 as much.

I plan to play around with this to see if I can further reduce them, but I highly recommend this simple and cheap tweak! The effect is maybe the same or a little more pronounced than installing spikes.

    So, after reading this I went an touched my speaker wires (Shunyata Anaconda with pig tails at each end), and did notice a small vibration. Then again the SPL is only in the high 60s, low 70s now. I am a big fan of vibration control with the speakers on spikes, and then on top of a 4" maple platform with brass carpet spikes. Also, all gear is on Mapleshade brass micro-point footers. As each piece of gear had vibration reduced there was a very apparent improvement.

    Thanks for the tip. I will figure out some way to reduce the vibration in the pigtails. It can't hurt, but I am not paying $200 for Acoustically Tuned Speaker Cable Pig Tail Vibration Eliminators. At least not today. :smile:

    Me neither! This was so simple (and cheap) and the effect is easily noticed.

    I have my 2.3TL's spiked, and I damped the Xovers when I rebuilt them, but they're still inside the cabinet. Sealed cabinets like the SDA's build up internal pressure to control the MW's and drive the PR's. That's where the vibration is coming from. I'll probably do a little more dampingon the banana plugs.

    I think moving the Xovers outside the speakers would be a good move, but that will be a future project.

    I have the speaker wire for the highs connected with spades and tightened securely - there's not nearly as much vibration to the touch. Perceptible, but only just. Bananas are so convenient, but I suppose I should switch the connectors on the wire for lows to spades as well.

    This may be one reason spades are generally considered to be superior to bananas.

    I'd say put some music on and touch the binding post and the wire at that point. You'll know whether or not it's there.

    Could be caused by standing waves from the speaker itself.

    Something like that. My guess is that because it's a sealed cabinet there's no release of pressure from the driver cone excursion except from leaks in the cabinet, or through the MW dust caps. The pressure is what energizes the PR for the low bass.

    I can feel vibration on the back wall and a little on the side walls as well. This may have been designed into the speakers so I'm reluctant to do anything in the way of damping that can't be easily reversed.

    Does it varry with the music or is it constant?

    Louder = more vibrations, softer = less. It's not constant but follows the intensity/complexity/loudness/amount of bass present.

    What about the vibration to the wires on the inside of the cabinet? You think the vibration was heavy at the bananas stick your head in the cabinet.

    Are your drivers dinamated? I had a " ringing" or a resonence at 30 hrz on my rta's that I eliminated by dinamating.

    Good point! When I rebuilt my Xovers I damped the caps, but not the wires going to the MW's. Next time I open them up again I'll probably use some blue tack or rope caulk at intervals on the wires. I'll probably also damp the big Solen Inductors, even though they're supposed to be fairly immune to vibrations due to how they're wound.

    I ordered some damping sheets from Sonicraft for the back walls. As I recall TF66 you found that using only a couple of narrow strips (3-4" wide?) yielded the best results, rather than coveringthe entire back wall. Am I remembering that correctly?

    Unless you have your speaker wire coiled up next to a strong magnet, I can't imagine
    vibration of the cable having much effect on anything.

    Well, I've had them loose, and I've had them pinned down, and on listening, I couldn't tell any difference.


    FWIW, I haven't listened with and without a platinum pinky ring on my right hand, but I can
    imagine with considerable confidence that there wouldn't be an audible difference, and I don't
    need to go out and buy one to to be sure of that.

    Nice write up. I use the wire bare on my speakers and tighten down. I think it's the best connection as there is no relying on crimping. That's a good point though about the wire and crossovers in the speaker. Has anyone tried moving the crossovers and inductor to outside the speaker?

    It's not exactly frankenpolk, but I'm sure besides aesthetics there must be a reason. Most of us don't have to move the speakers too often, so if it does have a positive affect moving the crossovers to a mount outside would be feasable.

    Hmmm...I love these cheap tweaks, it has a very high WAF!

    I built new Xovers and moved them outside the cabs for a pair of Def Techs I own, but I haven't done it with my 2.3TL's (yet. . .) Vibration plays a part in quality/clarity of sound so I think it would probably help to move all those caps and small inductors out of a sealed cabinet.

    Getting ready to switch my bananas to spades, install some Black Hole and do a few other mods tomorrow.:cool:

    Thanks EV, I did. This appears to be a case where too much ain't just about right - it's too much :cheesygrin:

    Planning on using a 3" strip vertically behind both banks of MW's and a little behind the tweeters.

    Don't try to be logical. There are people here that can "hear" the difference when they put their speaker wire on isolators that keep the wire off the floor. They also can hear the difference between a 16 gauge power cord and a 14 gauge power cord.

    I haven't tried the power cord upgrade, but I did add a Belkin p30 conditioner. It came with an ebay deal or I would not have had it. I heard the difference and then was curious as to why, then looked on here and saw there is a good bit about power conditioners helping with sound. I wasn't expecting a difference in sound, I just thought it was a better surge protector. But there is certainly a noticeable improvement in sound, although not as big as spiking speakers. For me changing a power cord now makes sense, as well as upgrading the outlet.
