    We are truly in a golden era for sound reinforcement. Designers who’ve long been at the forefront of bespoke touring systems, are seeing the culmination of their work brought to the market as finished products the public can purchase. The real winners are the SR providers who can design a venue-perfect solution and deploy in a fraction of the time systems of exceptional quality.
    I’m old enough to have seen the stacked boxes approach, with which I have to say some were able to achieve a fantastic result, to stock catalog products including software that can be snapped together to exact design spec by installers without designer knowledge, quickly & repeatably, and which pack like a dream. For those of us tasked with mixing a performer, the difference is palpable. Shorter days, better result. What’s not to love?

    its interesting how different companies make very different design choices, this is a big departure from say Meyer with very wide front angle splays between boxes... I'm very eager to hear this real life, definitely makes more sense to my head than other approaches

    • @DaveRat
      @DaveRat  Год назад +3

      Yes the different design approaches are fascinating.
      Weight, size, maximum volume, fidelity, cost,, ergonomics (deployability) and aesthetics.
      Overlaying those onto any design you can usually see what they optimized and what they sacrificed.
      Increased angle gaps between boxes is it design choice to improve deployability at the expense of fidelity.
      Meyer typically tends to prioritize weight very low on the hierarchy. Also Meyer historically has tended electronically trying to fix things that are mechanically not optimized.

      I think this system does do a good job of making it easier to deploy a system and cover a room.
      You can fly the system up and bump the motors until the top box covers what you want and then using the software fill in the bottom side of the coverage.
      I do kind of miss that old school setup where you could fly everything up and figure out your coverage later rather than having to do everything in advance.
      This kind of allows you to take either approach

      @DaveRat  Год назад

      Volume yes but coverage no. Point source systems require multiple long and short throw box types to be hung in various configurations. With line arrays you just keep adding more of the same box so you can carry a bunch of the same boxes and scale the coverage
      Do you know of any world class bands that tour with point source systems?

    • @iSkyline1
      @iSkyline1 Год назад +1

      @@DaveRat Afaik Danley is more focused on stadiums, rather than touring. How come Danley can offer great fidelity with fewer boxes than with line-arrays in these venues?
      For someone touring different venues a line array is the best compromise, but it's a compromise nonetheless. Sure they can be made to sound great, but there is a lot of marketing and bias in the industry, just like with the goldenears in hifi-circles.
      Manufacturers like to claim their line arrays are "line-sources" for instance, when none of them are actually true line-sources. If they were, then output power would proportionally scale with the number of boxes in the array, i.e. +6db for every doubling of speakers. Yet none of them do that even remotely when you stack more than say 4, which can only mean there is plenty of interference which a true line-source would not have.

    • @DaveRat
      @DaveRat  Год назад

      Yes for permanent installs using large format narrow beam boxes can work well for long throw. The setup and rigging is complex but that is a good tool for the job.
      As far as line arrays in marketing versus what really happens I suggest just doing the predictions using the software where you can actually see what happens.
      The correlation between the predictions and real world at least with the top brands, is quite good and it's not marketing high it actually is predictable buildable scalable and deployable as the software shows.

    • @DaveRat
      @DaveRat  Год назад

      Looking at this model there is 3 x 10° boxes and 1x 60° in box as the maximum hang. Offering a baseline of 90° that can be expanded or reduced using beam steering in the vertical.
      The concept is based on systems this size equivalent to 16 x k2 covers the majority of the applications that this box size format would be used for. And I do agree for anything larger than 16 deep K2 applications moving on to K1 would be preferred

    Nice system!!! Can this new product be said to be a system that complements the limitations of the high-pitched up and down angle arising from the curvature of one element in the line array system? On the contrary, if you arrange all elements in a straight line, you will find that the wave guides of all the high-pitched drivers do not have a vertical direction angle of 0 degrees, causing interference with each other.

    • @DaveRat
      @DaveRat  Год назад +3

      My understanding is that through the use of beam steering and control over each individual driver they can compensate the curvature to be flat or to extend the coverage vertically
      My experience with the product is that it definitely sounds clear in the the mids and highs than individual element systems

      For the past few years we've had the JBL a12 in the Gobi tent at Coachella and right next door at the Mojave tent until this year has been K2. You could walk back and forth relatively quickly and hear the difference between the systems with multiple engineers over multiple days.
      Even with the disadvantage where the Mojave tent has just a plastic interior and the Gobi tent has drapery cover the entire inside, clarity differences could be heard though somewhat masked because of the increased reverberation of the Mojave tent.
      The a12 is definitely a full sounding and good sounding system one would be hard pressed to say it sounds equal or better than the K2. The main difference that was readily audible is the clarity of the mids and highs.
      Additionally the variable horizontal dispersion control using the horn flares on the K2 is extremely useful in reducing the amount of sound bounces off the side walls of the tents versus having the fixed horizontal dispersion of 90°.
      Being able to narrow the dispersion of the upper boxes to 70° and widen the coverage of the lower boxes to 110° and cannot be overlooked as a huge advantage.
      That said the cost of the JBL is lower and the entrance fee to owning is lower as there is not as strict of a minimum system purchase requirement. So for the budget-minded the a12 can be a good solution

    • @DaveRat
      @DaveRat  Месяц назад

      RCF makes good gear and quite good value for the cost.
      When comparing the manufacturers won first needs to define the scope.
      If you're looking for a certain product cover a certain application there may be many options out there or several options they can do a very good to excellent job
      But that's a product based comparison while looking at a specific application.
      If we broaden our scope and look at the manufacturers as a whole, then we start to look at things like how comprehensive their entire offering and product line is. And whether or not the various products they manufacture work well together and have similar Sonic profiles such that various products can be used in various locations while maintaining sonic continuity.
      And what are the design tools? How good is the software that they make that allows you to design and optimize their systems?
      This is where L-acoustics kind of leaves all of the other companies in the dust.
      The Sound vision software is so advanced and so accurate and powerful compared to the other offerings that it makes the other offerings look like 8-bit video games.
      Even advance manufacturers like D&B array calc looks like an old space invaders game.
      Compared to the 3D rendering of sound vision where you can drop probes and look at the frequency response anywhere in the venue.
      But looking at it the other way, most or minne applications Don't need this advanced precision and why product range with interchangeable enclosures offering similar sonic profiles.
      And so seeking out a highlight product from various companies for specific applications is often advantageous and the way to go
      Has a company that rent sound systems for large venues and festivals as well as install sound systems in a wide variety of music and corporate venues, L acoustics tends to be the optimum choice for what we do.
      One final aspect is to look at the artist riders and what they are demanding or requesting and invest in the systems that show up most commonly from the most demanding bands.
      And for that it brings us back to the initial comments of D&B, L acoustics, some meyer, JBL and Adamson. And a few other companies as well

      Yeah the auto filter is severely limited and only does minor adjustments. Where is the EAW completely relied upon it.

    Can I build a small home single room line array with simple capacitive crossovers with small mid tiny high and small degree center deviation over a short distance using cheap car audio speakers?

    • @DaveRat
      @DaveRat  Год назад

      Agreed that having multiple speakers reproducing the same sound causes issues. And the reason to have multiple speakers recreating the same sound is to increase output level and/or coverage when needing to cover larger spaces than a single driver set can do

    line array Vs. Unityhorn pointsource"

    • @DaveRat
      @DaveRat  Год назад +1

      Using the term point source when referring to sound systems is kind of confusing.
      A true point source is infinitely small and radiates the same sound in all directions and no sound system does this.
      The closest we get to point source is a single box with a single component or group of summed componentsfor each frequency
      Beyond that we need to array multiple speakers either vertically or horizontally or both
      So then you end up with either an array or a giant horn with a coverage for the entire area.
      If the array positions speakers horizontally you end up with more audible combinations that are less than ideal
      If you array them vertically the issues are less audible due to where our ears are on our head and how it's easier to walk side to side versus move our bodies up and down vertically for large distances
      When deploying sound systems for concerts, using large horns that have predetermined coverage patterns are not optimal
      And this is demonstrated by the fact that no major artist or tour travels with systems that lack the ability to be arrayed
      Those arrays are almost always in the vertical domain

    So he re the seam between L2 boxes- you guys refer to an ‘algorithm’, what exactly is happening and why is no one saying the words beam steering?

    • @DaveRat
      @DaveRat  Год назад

      It's not really beam steering and that you can't use it to expand the coverage. In order to maintain the sound quality the algorithm will smooth the coverage within the existing band or act as a high pass filter to reduce the coverage at the extremes.
      Beam steering is a term typically used to force the coverage beyond the areas that the horns are naturally pointed at

    • @DaveRat
      @DaveRat  Год назад +1

      Hmmm, just like a MacBook air that is faster and smaller is cheaper than a MacBook ?
      Usually, smaller lighter louder sounds better all increase price
      In designing sound systems and nearly everything, conflicting parameters are balanced.
      Making a loudspeaker louder generally makes it bigger, heavier and/or more expensive. Making it lighter means it sounds worse, is not as loud and/or more expensive. Making it smaller means not as loud, more dense weight, more expensive and/or sounds worse
      Pretty much th only way to raise sound quality, reduce weight, reduce size and maintain or increase max output and fidelity is to increase costs.
      It's a fun and tricky balancing act that few companies do well

    The L2 look really nice. But for me it doesn't looks like a new idea ?
    Fohhn Audio is doing "beamsteering" since like 8 years with the Focus Venue series...
    For me, Fohhn is like 10 years ahead in this type of speaker (even the Syva, 10 years before, fohhn had the LX series), but can't get enought visibility to be known...
    That said, i really want to mix on those new speakers !

    • @DaveRat
      @DaveRat  Год назад +6

      Beam steering is not new and unified waveguides is not new.
      Combining the two concepts and adding horizontal variable control into what I believe may be the best weight and size to coverage ratio out there while improving sound quality is what makes this special.

    • @dominusblandus
      @dominusblandus Год назад +1

      in addition to Daves comment the Syva isn't really comparable to the LX Series either. LX is a rather pure Linesource. Syva is more a combination of a more classic louspeaker-design with line-source-like benefits... more "like" a K2/K3-Box in a different order of drivers.
      That said physics will probably always be physics (..at least as we don't go to the strings and stuff :D ). HOLOPLOTs new system goes two steps further than Fohhn or L-Acoustics - with its own rather unique advantages/possibilities and disadvantages

      Lots of powerful systems out there and not unlike a TV sound bar any system that has multiple speakers with variable phase and timing, recreating the same source or versions of the same source, in the horizontal domain inherently creates unnatural phasey sounds.
      Holoplot is super impressive and can project different sounds into different locations and is an extremely powerful tool but perhaps like comparing a hammer to a crescent wrench there may be some overlap in usage but they're different tools

      @DaveRat  Год назад +4

      By combining four enclosures into a single smaller lighter version of the four, the savings on wood panels and reduction in wasted internal space allows higher output and more fidelity from a smaller lighter array with better sidelines.
      The challenge is the reduction in versatility because you don't have all the variable angles between but they did their research and optimized the enclosure shape based on the majority of deployments worldwide and added beam steering in to compensate such that it will cover a majority of applications.
      Additionally the reduction in deployment time by having 1/4 the cable connections and 1/4 fly attachments and 1/4 the cables is a huge asset that has very positive financial benefits.
      The reduction in truck space and flyweight while still achieving equal or better coverage is quite beneficial as well.
      It's very rare that I see nearly every angle of design parameters addressed and improved.
      Smaller lighter louder higher fidelity and similar cost
      At the expense of a slight reduction in low frequency response and versatility of array angles.

      Oh my, the VHD5 is a massive array of speakers trying to be a point source with electronic processing that bases its existence on how it is not a line array and that line arrays have high frequency issues due to gaps between the horns
      The L2 is a line array system that does not have gaps between the horns and solves the exact problem that vhd 5 says is the biggest issue.
      These are two completely different approaches but both do use some electronic beam steering which neither company invented.
