The venerable panel discussion is a staple of business communication. Yet it is often the most misused, misunderstood and maligned tool in the communications arsenal. Pity the poor speaker who signs up to be a part of a panel discussion. They’re often oblivious to the fact that audience expectations are high (we might have even paid admission for this experience) and therefore audience members are usually fairly critical. A panel speaker might as well walk on stage naked – he or she is that vulnerable. Most speakers have been trained on how to deliver a keynote to a large group. Yet the majority are far more likely to sit on a panel at a conference or industry event than to give a solo presentation. Sonos' big claim to fame is popularising multi-room audio, i.e. being able to play music across your entire house instead of in a single room.

No echoes or "too loud" hotspots. No damage to surfaces. Robust enough for outside in hostile environments. To protect the wood from moisture that will cause it to warp we need to seal it. A normal wood sealant or oil would dampen the wood panel and degrade the sound. So far the best solution I found was to coat the wood with a very thin hot coat of polyester resin. Developed for advanced military sonar technology, and in collaboration with the University of Hull.Removing the plates turned out to be a lot more difficult than I anticipated, I started with a very thin blade and pried between the plate and the voice coil... be very careful! Distributed Mode Loudspeaker (known as DML) technology is the use of one or more electro-acoustic exciters to induce a uniformly distributed vibration into a flat panel made of a resonating material. Micro Vibrations (low excursion) is good. High vibration (large excursion) from traditional speakers is bad. Latter can damage surfaces. Zenker decided to compare different types of speakers to find out if a modern flat panel loudspeaker can fill the acoustic gap. Four categories of loudspeakers represented by a market-leading product were assessed: smart speaker, flat panel, soundbar, and studio monitor. After thorough analysis, he wasn’t surprised to find that, in terms of acoustic parameters, the studio monitor performs best, followed by the soundbar and the flat panel. The smart speakers achieved the lowest scores. The lower frequency limit, comparable frequency response deviation, and an increased acoustic output, led to a higher preference rating of the flat panel loudspeaker compared to the smart speaker. Benjamin Zenker, from the Technical University of Dresden, and founder of ZEN Audio Engineering, has been developing loudspeakers for more than 15 years. During the last three years, he has developed simple and robust methods to improve the acoustic quality of flat panel loudspeakers by increasing the low-frequency output, extending the upper frequency limit, lowering the deviation of the frequency response, and optimising the directivity behaviour. His aim is to invisibly integrate sound within architecture and make flat panel loudspeakers an alternative to conventional speaker systems.

This is the basic if you are starting, but if you want to ace the panel, here you have 11 things you can do to ensure that you hold up your end of the panel discussion: Know Your Audience The low visual profile offers opportunities to integrate larger and more powerful devices with higher acoustic quality than smart speakers.” Upper frequency limit Low-frequency performance is a physical problem for flat panel loudspeakers resulting in less output and higher deviations in the frequency response. Zenker reinvestigated a hybrid woofer-driven design to improve the low-frequency behaviour of flat panel loudspeakers. The woofer is part of a speaker system designed to reproduce low-frequency sound signals – the bass. The hidden woofer excites the whole panel uniformly and offers huge improvements when compared to an exciter-driven panel. It is a simple and robust construction, which can be mass produced. The panelled woofer design produces a low-frequency bass response similar to that of a large conventional system. Shellac is not that hard to find here in Australia and I know of many places you can buy it in the USA. That said, I do not know where you are located so a little hard to offer more specific advice. Being part of a panel discussion is a bit of an art form. There’s a fine balance you must always keep, and that is being part of the group while at the same time standing out as an individual.Now if you made it with the included circular design you can just line up the cone with the design otherwise you will want to make sure to place it over where the exciter is on the other side. In other words, if I was in the middle of the woods with just the speaker and my phone, would I be able to connect to it and stream to it using WiFi?

Pros: Electrostatic speakers, like ribbon speakers, excel in transparency and accuracy, making them well-suited for vocal, classical, and jazz genres. Their ability to faithfully reproduce intricate details of the audio enhances the listening experience.Grab the Moment: Unlike a speech, you do not have total control as a member of a panel. It’s unlikely that you’ll tell your story in one pop. A panel is an exercise in navigation, and requires a speaker to build perspective through smaller sound bites. You have to spot the opportunities and grab them. Opening introductions is your first chance to offer a short summary of your point-of-view, and you’re likely to be designated a slot of time that is entirely yours. Other moments you can own include relating your story to a question from the moderator, providing a build from another panelist, or using a question from the audience as a way to launch another dimension of your story. The large size of these speakers can be a negative in small spaces, although the ability to hide them inside walls or as artwork can easily overcome this limitation. Limited low end frequency response (although large panels can be made to produce a low frequency response, this is usually a balance between speaker size and the desired frequency wavelength).

This huge response spike between 2,000 - 5,000 Hz is very noticeable when listening to large DML speakers for the first time. I even covered the panels with soft but heavy towels to dampen down this spike. Just turning the treble down is usually not enough. It can be quite painful to listen to these types of speakers very loudly without a Digital Signal Processor (DSP). Digital Signal Processing (DSP)I've been invited to be on several panels, mainly to talk about Business Strategy, Artificial Intelligence, Technology, and similar topics and I can say I always have a lot of fun while doing it and I've been sharing valuable knowledge for a very qualified audience in several countries. First you want to sand the entire panel with 400 grit sandpaper, careful not to go too deep or you'll remove the laser pattern.
