Incoming: Lansche 4.2 with the Corona Plasma Tweeter

Congratulations, a 180 degrees for sure; will miss you at the Magico fan club.
No doubt there is nothing like a plasma tweeter, but like mentioned, integration is a challenge. You may also want to make sure you have proper ventilation in the room; I believe these types of drivers may emit ionizing radiation.

My enjoyment of the Magicos will not go away, no worries. It’s just time to try something else. No rest for the wicked [emoji3].

Due to the speed of the Plasma tweeter integration is always difficult, but to my ears this has been addressed to satisfaction in the 4.2.

In earlier versions by Braun there were there were some emissions, but that has been resolved by Lansche in the meantime. But the do obviously produce some heat, maybe a bit less than my earlier Pass amp.

Where in the Lansche web site are the active speakers? I can only find the P series as in passive and H horn speakers.

No 4.2 semi active or any semi active speakers.

The semi-active versions are now made by custom order only. That requires changes to the crossover and external power amps, which Lansche also offers. How that looks is shown with the new 3.2 below, also a neat concept. I got the last one with the amps integrated.

The nice thing with Lansches is, they continue to evolve after purchase through factory upgrades. No more being left stranded with the previous generation after a mk 2/ 3/ 4 launches.

Congrats, Kuoppis. Can’t say it came as a surprise knowing how you feel about the constant short product cycle. Sounds like you’ve found a worthy replacement.

Much has been talked about the plasma tweeter. I’m also interested in how you think about the bass performance compared to your S3 mk2.

It seems this 3-way from Lansche has a very high efficiency, and since high efficiency speakers tend to sound more imediate, maybe it somehow overcomes this problem (to the point where it becomes acceptable).

I would very much like to hear that speaker in my room.

Adam, that is exactly why I went for this model. Or there are actually a couple of reasons.

High efficiency horns have something mesmerizing. The immediacy of the the sound is very appealing in general. Paired with the unique properties of the Plasma tweeter it creates an immediacy to the sound, which is hard to achieve with regular tweeters.

Second thing is the bi-amping in this semi-active concept. This is splitting the usually wide impedance spread between the tweeter, mid, and woofer drivers. That also helps significantly to achieve better coherence. Another ingredient is the speed and high frequency capability of the Soulution amps, so I would recommend fast amplification with good bass control. But of course a trade-off remains, in this particular concept I find it indeed acceptable.

Can’t offer you a demo in your own space off-the-cuff, but you are welcome to come and listen to my setup should you be close-by for business.

Hi Khin, this time I did not switch due to the product cycle. The S3 mk2 is still the current model. It’s more like I started listening to various horn-loaded models, and was taken by the immediacy of the sound. More “being there-ness”. I know that sounds odd, there is no such expression [emoji3].

And you are right, I’m spoilt related to bass performance due to the Magico experience. But these babies have two 10” aluminum woofers, powered by a dedicated 1200 W amp. That makes the bass fast and taut. The difference is, through the active adjustments I can choose between the Magico type and shattering earth quakes. I have the bass on a moderate setting as I like good definition in the lower register.

I think I know what you are talking about regarding immediacy. It may not be exactly the same as what’s coming from high efficiency speakers, but when I added Diablo 300 and its 600wpc for 4 ohm (along with Denali and Hurricane pc), I felt it finally does the system justice in immediacy, coherence and dynamics.

As for Magico bass, for the music I listen to most, I haven’t found a better brand. YMMV of course.

It is indeed similar. Through better amps you get improved dynamics, definition, and maybe clarity in the playback.

With horn-loaded speakers, the listener appears to be closer to where the music is happening, and to get more details. This is very strongly amplified through the speed, frequency range and high resolution of the Corona tweeter. Soundstage depth and width is also increasing, you have a feeling of being able to hear the different layers in the music. The music is kind of floating.

seems bizzare if what you say, that the semi active are superior to the passive models, yet the semi actives are custom order only?

I talked about that to Rüdiger Lansche, and made the exact point you just made. He explained to me that the majority of his customers nevertheless seem to prefer passive speakers. That appears to be market preference. He is clearly recommending bi-amping though.

And that does not mean passive is necessarily better. [emoji3]

Just did some testing with 30-40 tracks I am very familiar with, to evaluate the 4.2’s coherence. My conclusion is that if there is an issue, it’s at least not very noticeable. But I found something else.

Listening for a couple of hours, I did slight adjustments to the positioning every now and then to optimize speaker placement, angle, distance from the front wall etc. These are my observations:

The Lansche 4.2’s paint an exceptionally wide, deep and well layered soundstage. I have never heard anything like this. This is also because you can hear more details than you usually do (remember, I’m used to Magicos). Musicians, instruments, solo vocalists, backing vocals, orchestras, and layers of the music can be heard exactly where the recording engineer placed them. It’s easily audible whether the vocalist stands slightly left or right of the microphone, or how the combo is positioned on the stage during a live take, or how the recording engineer layered and mixed instruments in the piece.

Retrieval of ambient information is exceptional, whether it’s Eva Cassidy on a club gig, or Elisabeth Schwarz singing the aria of the Queen of the Night in Karl Böhm’s recording at the Bayreuth Opera. Recordings with special attention paid to layering and channel interplay, like Queen’s Bohemian Rhapsody, are presented in all their artistic sophistication.

Slight challenge is that dialing-in the Lansches perfectly will require great care to be perfect. Also, I believe it’s very difficult, or might even not be possible to achieve a perfect result, if your listening space is not properly acousticed, like e.g. in a trade show room. But after going through the pains the end result is really rewarding.

Kuoppis, just catching up on this exciting change. Didn’t see it coming! Very pleased you have found speakers that better the S3 mk2s. Wow. Am fascinated/curious. Keep the reports coming!

Thanks [emoji3]. I’m quite excited about the change. The Lansche 4.2 is a great speaker and really takes my system up a notch.

Both are great speakers in their own right.

But this is the next step for me now. And I’m quite enthused [emoji1739]

Wow, that was a surprise. Congrats! Need to give Lansches a good listen in Munich.

Yes. But I must confess I have been eying the Plasma tweeter for a while already. [emoji3]

I hope they will have a semi-active version there. Was e-mailing with Mr. Lansche yesterday, and he again emphasized the importance of bi-amping.

Congratulations Kuoppis!

Great to see your glowing praise for the Lansches.

I am also one of those who didn't know what quite to make of Lansche from my listening at Munich (2017). I did get a glimpse of the speed of the tweeters but could not get enough of a listen to gauge much more than that. Your experience shows how important the role of a good distributor is in allowing you to listen to them in your own setup. Very interesting to read up on your impressions of the models from within the Lansche lineup.

For a speaker to get you to move from Magico really does say something ... enjoy!

Regards

Thank you for the kind comment.

The Lansches are indeed great, and it is very important to hear them in your environment.

I do like Magicos, but with the Plasma horn tweeters the Lansches are more life-like.
