Schu Posted January 21 Share Posted January 21 You're trying to tell me that there is a physical displacement issue between the HF and LF that exacerbates a side wall resonance? you're joking, right? so you can place your hand on the HF during playback and physically feel it vibrate at say 85bd-90db? they're your speakers to be sure, and you can bolt the HF to the LF for all I care, but don't think your 'discordant interaction' anecdotal experience is anything but... anecdotal. 1 Quote Link to comment Share on other sites More sharing options...
Don A. Childs Posted January 22 Share Posted January 22 My point about isolating the HF bin from the LF bin was...resonance overall not specifically at a certain frequency. We know the bass bin produces tremendous vibration. This in turn vibrates the upper bin and both horns in the Lascala. (And the side walls, etc.) Without this bass vibration effecting the upper so much (my 'iso-puck 76's don't quite really 'isolate' but minimize) the over all clarity is enhanced because the resonance throughout the frequency range is not (so much) allowed to have this polluting effect either on the top or bottom. Its a little like placing an opera singer on a vibrating surface as she sings. Her voice will be effected by shaking her as she sings. Well, despite the poor illustration, I'm still curious if Lascala II or AL5 owners can try this and let me know if it doesn't improve audible clarity. If it doesn't then it doesn't. Maybe my floating yurt floor was the problem needing a solution. The same clarity happens when vibration is eliminated from turntables, CD players, speaker cables, and amplifiers. Anecdotal is the best I've got. But if anyone else tries this and discovers an improvement I'll have an anecdotal friend at least. Quote Link to comment Share on other sites More sharing options...
Shakeydeal Posted January 22 Share Posted January 22 I did something similar to a pair of Von Schweikert VR4 Silvers back in the 90s by using a semi inflated bicycle inner tube. It did make a difference. 1 Quote Link to comment Share on other sites More sharing options...

Everything vibrates. YOU are vibrating right now as you read this. Vibration control is a real thing and most every component in your system benefits from it if you are willing to put forth the effort. It's also another reason why massive entertainment centers are detrimental to the sound. What you sit your components on matters, so why wouldn't you expect vibration control to benefit speakers? 2 Quote Link to comment Share on other sites More sharing options...
Don A. Childs Posted January 23 Share Posted January 23 Maybe its just my hands shaking from too much bourbon last night but....(punctuation misuse of ellipsis intentional "for effect").....putting my hand on the bass bin I can feel significant vibration in certain places on side walls. Obviously this isn't all bad even as it is equally obvious its unavoidable with that driver pumping out bass frequencies. However, whatever we may think about these "good vibrations," the empirical test is actually having a Klipsch Lascala owner [AL5 or II only] put something between the two bins and objectively report the results. With mine I noticed that now I enjoy a little higher volumes much more due to the HF bin not being 'disturbed' as much. Notwithstanding, everything vibrates constantly throughout the universe.

Mikekid Posted January 23 Share Posted January 23 Some have a problem writing and typing, I sure do. A stroke screwed up my left side and hand, and I forget tapping keys all the way constantly. But usually my point is made without an English lesson from an indoors type.. Just be glad I was once a rocket scientist. I was given a ration of unnecessary sht from someone a few days ago ..not here though. 👌Another day out of bed. Blessed...~Mike 3 Quote Link to comment Share on other sites More sharing options...

As a LSII owner I can confirm that the bass bin does get some decent vibration if you crank them loud, Loud as in 112db at 10 feet. But the LSII tophat has large rubber feet that fit in sockets on top of bass bin and even at that SPL lvl there is only a tinny amount of vibration in the tophat.The bigger issue by far is the ductwork rattling in the ceiling, pictures rattling, stuff falling off shelves ect 3 Quote Link to comment Share on other sites More sharing options...
KT88 Posted February 7 Share Posted February 7 @Flevoman I noticed something with my interlink cables that reminded me of the resonance problem with your LaScala. I have always used ready-made RCA cables, most of them with one running direction. Often the shield was only connected on one side, and the conductors were " quasi symmetrical". Now, out of curiosity, I have made up my own cheap Canare L-4E6S interlinks. The net is full of a lot of wrong and maybe right advice on how to configure an RCA cable. Most people say that they only connect the shield on the source side. The Canare L-4E6S is actually a star-quad microphone cable, it is used successfully in many studios as an XLR cable as well. On the forums of sound engineers and studio workers, however, it is emphasized that this cable must have the shield connected on both sides, even as an RCA cable, because only then does it really shield. In addition, the negative conductor together with the shield should have an even lower resistance than the „hot“ wire. Be that as it may, I tried it out and ended up using my ears as a benchmark. 1) Canare with only the shield on the receiving side: cloudy and undynamic 2) Shield only on the transmitting side, very dynamic but with just such a dull resonating sound around 100 to 150 Hz. 3) Shield on both sides: The thickened, flabby upper bass range has completely disappeared, even on different speakers. It is a clear and very defined spatial sound image with deep resonance-free bass...at least there is no added boominess. Now I don't know if you are using RCA cables at all. But if you do, are they quasi-balanced cables or do they have the ground connected on both sides? If you happen to be using quasi-balanced cables, try a different RCA cable that has the shield connected on both sides, even if it's a cheap one just for a try. My next experiment will be RCA coax cables. A very friendly Japanese employee of Canare in Düsseldorf recommended them to me on the phone as the best for RCA. I don't know if my post is of any significance, but I didn't want to leave it untried 1 Quote Link to comment Share on other sites More sharing options...
