Carlsson ortho-acoustic loudspeakers sound
They say that great style is timeless, and that rings especially true when the style in question happens to be greatly ahead of the curve. And with a host of 21st century upgrades, the OD Cloud Speaker is a whole new box of wax. Built around the same ortho-acoustic meaning upright , omni-directional sound pattern as the original, the OD Cloud Speaker brings watts of Analog Class D amplification to the party, for the latest take on powerful sonic efficiency. Sound is pushed by premium drivers, including a long-throw pulp cone woofer, and a ferrofluid-cooled cone tweeter.

Moi tuossa mukavaa tietoa asiasta kiinnostuneille This involves a change of directivity of an emphatic sort—from omni to half-space radiation. With the popular narrow-front floorstanders of today, this transition occurs somewhere from —Hz, an unfortunate location for an abrupt change in radiation pattern.
People seems to have decided to ignore this or at best to make the transition as gradual as possible, but this does not make it cease to exist.
The drop is theoretically 6dB. The way to cope with this in such a speaker is to control the radiated SPL in the crossover in such a way that you attenuate the sound above the baffle step frequency to match the SPL below..
This essentially lowers the sensitivity and output SPL of the loudspeaker. One other way of addressing the problem is to add one more driver connected in parallel with the first bass driver and a crossover design that gradually lets this extra driver fill in the missing 6 dB.
Drivers connected in parallel will draw twice the power from the amplifier in this region. The actual change of directivity is still there in both cases even when it is masked by the change in output SPL to make it not obvious… All Larsen loudspeakers are free of this baffle step because of the wall placement.
A speaker with a high-quality power response in the lower frequency regions even at really high SPL. The Larsen 6 has a linear frequency response down to well below 30 Hz! Anders got back to the drawing board together with John and the result was almost a surprise to us all… The new Larsen 8 was not a Larsen 6 with a subwoofer… It was so much more!
It had rich, deep and precise bass with very low distortion all the way down to below 25 Hz. A very natural sounding body in the bass region. In the Larsen 8 as well as the Larsen 9 the main drivers are located at the top of the speaker is diagonally mounted directed upwards and inwards the same way as in the Larsen 6. Located at the floor on the side of the loudspeaker there is a second driver identical to the main one. Instead the crossover point is set around Hz.
The reason for this frequency is to minimize the loudspeakers all loudspeakers problem with the reflex from the floor in between the loudspeaker and the listener. If it would be only to address compression and distortion it would probably be fine with a Hz or so crossover frequency. In a traditional loudspeaker the extra woofer would add the missing 6 dB of SPL by both drivers playing the same sound in that frequency range twice as loud together.
In the Larsen 8 and 9 the drivers instead share the work load, both drivers playing half the SPL each. The benefits are lower distortion half the cone movement for same loudspeaker SPL , more uniform bass in the room due to double the points of radiation of sound, better coupling to the air while radiating bass sound due to twice the cone area, suppression of reflex from the floor.
All together creating the signature natural sounding rich, deep bass found in the Larsen 8 and 9. Sustainable Sound Design from Larsen Hifi It is not an exaggeration to assert that people more and more are striving to incorporate sustainable solutions in their homes.
We think this trend is good. The fact that people think more about quality to keep things for long goes well in hand with our philosophy for sustainable sound design. What do we mean by Sustainable Sound design? We are true to our origin: The ortho acoustics.
Instead, we improve. The best evidence we have for that is the fact that for six years in a row, Larsen 8 has been awarded with Editors Choice Award from one of the world leading hifi magazine The Absolute Sound. With the ortho acoustics design, we are different from other high-end speakers, and some sales arguments are probably the selling point we can offer you as a distributor or reseller.
No compromise! Just place them with no toe in, plug them and play. This placement to be placed against the rear wall, or at least not more than an inch or two away from the wall, is part of the ortho acoustics principle and a significant trademark for all Larsen speakers.
It is part of the sound design and all to avoid early reflexes. On this point, Larsen speakers are among the very few speakers that compromise friendly to the one who care both for the home furnishing as for the good sound. Many reviewers have figured out that with Larsen speakers you get the ability to reproduce the sound from the concert hall in a normal living room.
Flush against the wall Larsen Hifi The sound stage Many have been surprised when they listen to a pair of Larsen speakers for the first time. The reason is that the sound is far bigger than their size will suggest, and the sound stage is surprisingly well defined. When you have put the speakers against the rear wall and about a half meter from the sidewall, you can move each speaker sideways, and listen, until you think you have the right sound for your room.
Just remember to have the right-sided triangle in mind when you figure out the distance between the speakers. Out of the speakers, you get a big airily sound composed of direct sound and the reflexes from boundaries and furniture in the room.
A total stereo sound fills the room thanks to the angled drivers in the top. You will feel the depth in the music without sitting in the exact hot spot! You can sit nearly anywhere in front of the speakers, and you will get a lovely sound stage. Just like live music. Listening room Reclaim your living room as listening room When Stig Carlsson developed the first ortho acoustic speakers he had no special lab. No, he used his own living room. They had one purpose in mind: To use the same method as Stig Carlsson but in their own way in their own living room.
The foundation was made and this is what you will hear today when you listen to a pair of Larsen. They are made for the normal living room and for the whole family. No refurnish needed! Not made for any special music! Just play and enjoy! Yes, we are different! No "baffle step"! No doubt about that we are different! This step, however, is nothing that exists in real-life acoustics nor in the Larsen speakers. The reason is that the wall placement provides half-space directivity already in the bass.
Here within is one of the secrets to the lifelike authentic sound of the Larsen speakers. We are proud to be different. And we are proud to be the company bringing the Carlsson OA principles to new generations of listeners. All the best from Hans, Preben and John.
In-wall Speaker Measurements (Monoprice THX-365IW)
Concert venues are closed; cinemas are obstacle courses of hygiene theatre; your favorite artist is on the third leg of a world tour played entirely from the acoustic wasteland of their own basement. Perhaps there is someone in your life who, like me, reminisces about the experience of being spilled on by a stranger at a music festival. And if there is, you're in luck; you can give the gift of sweet music technology this holiday season to dull those idle reveries, and you can do it at any budget.

Larsen 9 Loudspeaker
Larsen is a Swedish loudspeaker brand whose models are specifically designed to resolve this conundrum by working with, rather than fighting, sound reflections. Constructed to thrive and perform phenomenally in a normal room, they use surface sound reflections to their advantage to enrich the listening experience rather than degrading it. Larsen loudspeakers are designed to stand flush against the rear wall of the listening room, using the wall to create a deep and full bass from a relatively compact cabinet. This placement, combined with the unique positioning and angle of the drivers, which are flanked by absorption material, virtually eliminates the wall as a source of colouration.

My open baffle project on ortho acoustic design ideas. This project has been a long time coming, and I hope it can be of interest to some of you out there. Their chief engineer G P Millard investigated the possibility to use dipolar speakers to increase the sweet spot area for stereo listening. This opened my curiosity towards dipolar speakers. Born and living in Sweden with a burning interest in sound reproduction, you will likely come across the late great speaker designer Stig Carlsson and his unconventional designs. He pioneered a lot of work on how the speakers should be designed in order to interact with a normal living room to create a believable lifelike reproduction of recorded sound, together with the likes like Roy Allison, Peter Snell, Jim Thiel, Harold Beverage and others. He named his principals ortho acoustics and has been a huge inspiration to my own designs. And since the HNRR article in I have also been experimenting with dipolar applications to these ortho acoustic design ideas.

For many years, the Larsen 8 speakers were the pinnacle of ortho-acoustic design and once experienced by music lovers, audio enthusiasts and audiophiles around the world, justifiably developed a reputation as one of the most engaging and musically satisfying speakers available at any price. That day has arrived with the introduction of the new flagship in the range, the Larsen 9. Improvements were made in many aspects including materials, drive units and cabinet geometry. The unique positioning and angle of the drivers, flanked by absorbers, creates a rich and deep three-dimensional sound stage, with far more detail and better ambience than the existing Larsen models. The stainless steel plate surrounding the tweeter is the same design as the Larsen 8. The two bass drivers working together under Hz, create a deep, fast and precise bass extension with very low distortion all the way down to 22Hz!
