  1. Thank you so much for the effort you've put into this, @mikebse2a3. This really gives me some insight. When I listen to your audio file, I can clearly hear the thickening. It might not be as pronounced as on the La Scala, but this could be due to the recording and playback through my earphones. I recorded a piece of music with my phone and listened through earphones to compare with your recording, and they sound quite similar through the earphones. It's not conclusive yet; it might still sound a bit more pronounced on my end. However, I'm starting to think that what I sometimes hear as a resonance is likely present in the song itself, enhancing the La Scala and possibly amplified a bit more in my acoustic environment, making it unpleasant for me. I'll mention it here when I come across another track. Could you please test it again on your La Scala to see if you can hear it too?

  2. Very clear and plausible explanation @KT88. I also searched for a while in the recordings themselves. This resonance I sometimes hear is (perhaps logically) only present during dynamic sections.

    However, since songs that pose problems on the La Scala seem to perform well on other speakers, I was unsure where to pinpoint the cause (which is why I started this topic to exclude if it's a speaker issue). Just to clarify for myself, does this song sound unpleasant to listen to due to resonance on your UJ (as I understand you also experience something similar on the UJ)?

    I'm wondering if it's even more pronounced in my setup. Playing this song over the La Scala is genuinely not enjoyable to listen to.

    definitely , the Cornwall IV has the same midrange driver as the Heresy IV +  the advantage of a much larger midrange horn ,  here's a video showing the CW IV going head to head with the JBL 4367 Studio monitors worth 3 x the price 

     

     

    I switched from the CW3 to the CW4 myself. The CW3 is worth about €2500 on the second-hand market in the Netherlands, while the CW4 is around €5500 to €6000. Whether the audible difference is worth the price gap is a tough call for me. However, the CW4 is undoubtedly the superior speaker, and if the financial flexibility allows, I can definitely recommend it.

  4. I really have to agree with @Shakeydeal on this one. Personally, I'm the type of person who struggles to hear differences. Speaker cables and interlinks, for example, all sound the same to me (at least from what I've tested so far), and the same goes for DACs. I've tried a few but can't really hear any differences. Where I can notice a distinction is with amps. Sometimes the differences are subtle, and other times they are quite noticeable. So, do yourself a favor and truly give the topic of amps the attention it deserves.

    You mean right where his vocals come in? Really obvious... Very much there in my inexpensive Sony headphones I have at work,

    Yes, exactly when he start singing. 

    I have listened on my Sennheiser ear buts and on my Sonos system (2x Sonos 1 + sub), both not hifi but decent, and I can hear on both his voice is warm and deep but it it is in balans. On the lascala I can hear a loud resonance that's very unpleasant. It's almost if the speaker can't handle it and there for is creating some kind of wooden vibration. 

  6. I always swipe away the songs with resonance immediately, so it's a bit of a wait until another song comes along that clearly showcases it. I've already heard some songs with it to a lesser extent, but I'm trying to find a very clear example. This song definitely has it. As soon as the singing starts, I hear a very strong resonance in his voice. When I listen to this song again on my Sennheiser Earphones, I can hear the warmth in his voice but not that exaggerated/resonant sound.

  7. I use Tidal, and I really like it. The reason I prefer Tidal over other, sometimes half-priced, streaming services is due to its offering of high-resolution music and the user-friendly app. Additionally, there are features, like "my daily discovery," where I get around 10 songs tailored to my music taste every day—an enjoyable way to discover new bands. Another great option is a button under the song that you are listening at. It generates a complete playlist of similar songs. Maybe it might be a bit pricier than some other streaming services, but I'm very satisfied with it.

  8. Ahhhh.. Thank you for the explenation 

    Unfortunately I don't have anything like that. 

    Perhaps in the future I will by a mic for doing tests like this. 

    But I did try a Hertz sweep to find any reconance somewhere. 

    The only thing I heard where 3 small dips but not the sonic resonance I am talking about.

    How's about hook up REW, turn on the sig gen and find the annoying frequency? Just an idea. And does the annoyance change as you walk about.

     I have no idea what you are talking about, sorry 😄

    REW, sig, gen...what does these words mean? 

  10. I want to share some experiences and thoughts if that's OK, and I'd love to hear what you think about this.

     

    Years ago, when I first started this hobby, I had the LaScala 1 paired with the Dynaco ST70 II. Back then, the internet was barely a thing, I had no friends who shared this hobby, and my only gateway to this hobby was a small audio shop that didn't deal with Klipsch or tube amps. Through them and a series of connections, I could gather information or get equipment. Regardless, I was advised to modify the Dynaco with KT88 tubes. After submitting the amplifier, when I got it back a few weeks later, the sound was very unpleasant – dark and with a bothersome resonance (similar to what I hear now but much stronger). I'm unsure if the modification was poorly done or if it was supposed to sound that way, but I increasingly grew frustrated with the dark sound and resonance. It's been so long that I can't remember if there was already resonance before the modification and if it only got worse afterward. In any case, after the modification, the enjoyment dwindled, turning into frustration until I eventually stopped the hobby. I was young, less vocal, had no internet support like now, and the audio shop couldn't help. This led to the LaScala being stored in the garage for years, while I listened to a Sonos set.

     

    Now, revisiting this hobby with more resources, I've often read about the LaScala 1's resonance. Every time I read about it, I thought, 'Yes, I recognize this.' However, now that I hear a similar resonance with the AL-5 (though significantly less), knowing that this speaker is not known for resonance problems, I begin to think that the resonance I heard with the LaScala 1 may not have been related to the speaker. Perhaps the Dynaco modification exaggerated an existing issue, but the cause isn't the speaker.

     

    So far, this all makes logical sense. But here's the confusing part (at least for me): Before buying the AL-5, I was torn between the newest Khorn or the LaScala. I had the opportunity to listen to the Khorn at someone's home. While listening, I immediately heard something I hadn't heard in all those years – that annoying resonance at precisely the same frequency in a specific song. I only noticed it in one song, but it was unmistakably present. And this is challenging to explain. Is this something inherent to the LaScala/Khorn that I'm particularly sensitive to, or do this person and I share the same issue?

     

    By the way, I can best describe the sound as something similar to the boomy quality sometimes found in deep bass in some speakers. The bass tones sound well-balanced, airy, and then at a certain frequency, something goes wrong, and you have a boomy sound. That's roughly how the resonance sounds here and with that person, but in the mid-low frequency range.

  11. A lot of comments, some of which are certainly valuable. Thanks to everyone for thinking along and sharing experiences. The knowledge and help on this forum are truly superb 👍🏻

     

    I started this topic with the question of whether the AL is known for resonance problems at certain frequencies. After reading all the answers, it is clear to me that this is definitely not the case. That means I shouldn't look for the issue in the speaker itself but somewhere else. Perhaps standing waves could be the reason? . I'll use the upcoming holiday to rearrange the entire living room so that the speakers are positioned lengthwise. I'll also reinforce the sides of the bass cabinet with a plank and clamps. I don't expect this to improve anything (since the conclusion is that the speaker doesn't have known resonance problems), but it's a small effort, and I want to rule out everything.

     

    As for future upgrades @KT88, no... I've let go of the Klipschorn as I don't have corners to place them in. That would mean I have to place them against the long wall, and everyone here advised against it. However, I am eagerly looking forward to the upcoming Heritage Subwoofer series. I have high expectations, and I hope this will be a nice upgrade.

     

    It might not come across this way, but the AL-5 is definitely not leaving. I enjoy these speakers every day and find them truly amazing as they sound now. Despite the annoying resonance I can hear in some songs at a certain frequency. Even if I can't solve this, I'll keep these speakers because of their musicality. But of course, my hope is to get rid of this last blemish. 😉

    If you  think resonance is a  problem , try clamping on a stiffener to the suspected area , like the outside horn edge for example ,  then  compare results , test tones will be helpful . This way you can see for yourself any positive change ,Good luck 🤓

    I was thinking of using a wedge in the bass cabinet. But you're right, I could also secure a thick plank to the side of the bass cabinet with clamps. Logically, this should reduce the resonance (if indeed it's the bass cabinet I'm hearing) from the side walls.

    Yes, they resonate.

    Bracing will help a lot but it won’t tame some of the irregularities in frequency response that are inherent to the LS due to compromises in the horn expansion.

     

    if you have an active DSP setup that is capable of some parametric EQ adjustments, you can try the following settings that are known to ameliorate the response of the stock LS bass bin.

     

    87hz, Q:3.5, +5dB
    148Hz, Q:8, -7dB
    380Hz, Q:5.5, +2dB

    Maybe I didn't express myself clearly. I understand that every speaker resonates. I was just wondering if the resonance in the La Scala II / AL-5 is still significant enough to be a audible issue at certain frequencies, or if it should have truly disappeared by now. This was a common concern with the La Scala I, often addressed by using a wedge in the bass cabinet, if I recall correctly.

    IMHO based on experiences having owned both the original La Scala model as well a the La Scala AL5 is that it is very important to pay attention to how we position the speaker relative to (SBIR) Speaker Boundary Interference Response and Room Modes.

    Thank you Mike. As often, your assistance is thorough but also very technical 😉. Unfortunately, I still lack the technical insight to fully understand everything. However, I understand your explanation that the resonance I hear may not be from the speaker but due to its placement.

    I've already tried moving the speakers around, and it hasn't had much impact on the resonance I hear. But next week, during my three-week vacation, I will experiment by placing the speakers lengthwise to see what effect it will have.

    Thank you for pointing this out.

    Known for its resonance?  Really?

    Sorry, I can't tell if this is a dig or a well-intentioned wink. With my comment about the La Scala 1 being known for its resonance, I meant nothing negative, in any case.

  15. Thanks for the replys

    When I switched from the CW4 to the AL-5, there were a few points that bothered me. Now, after trying various amps, adjusting placement, and making other tweaks, most of the issues have disappeared—enough for me to enjoy these speakers. However, there's one point of annoyance I would really like to eliminate or at least reduce significantly. It's a kind of resonance that I can hear in the mid-bass with certain tracks. It sounds like cabinet resonance, but honestly, I have no idea where it might be coming from. Midhorn? Bass cabinet? Or something else? Due to some factors (which would make this a longer story if I were to mention them all), I suspect it might be a form of cabinet resonance. Hence, my question. But from what I gather, the AL-5 should be free from this, according to feedback.

  16. I'm currently pondering the best approach to address my issue. It could be through a lengthy detailed text or perhaps a shortcut. I'll opt for the shortcut.

    The LaScala 1 was known for its cabinet resonance. I believe this was addressed by placing a wedge in the bass cabinet to reduce the resonance. The LaScala II and the AL-5 have thicker walls. Is the general assumption that this completely eliminates the resonance? Or is there still some resonance present, and could, for example, a wedge in the bass cabinet still provide improvement?
