Title: Yorkville Synergy Line
Post by: Douglas R. Allen on January 25, 2019, 07:55:29 pm
Yorkville has a new Synergy Line. Looks to be a solid replacement to the me too speaker on the stick type setup.  Danley designs incorporated in it.

From the Danley Users Group FB page:

Hi All
There is a bit of an issue / confusion with the name of the series. This is my fault not Yorkvilleís, although I didnít remember it.
I had Hernia surgery a while back and leading up to and afterwards for about two weeks I wasnít myself mentally. All I can say is anesthesia and pain meds are weird and take a while to wear off or did for me.
After being reminded of it, they did bounce the name off me and I said I thought it was ok.
As we are getting better known I should bounced that off the others at DSL but at that time it didnít occur to me. Anything like it the future will not suffer this mistake (and I am not going to get another Hernia lifting big sub woofers).
Itís been a long time since I went to NAMM, but I wish I could hear their new system myself.
Best Regards
Tom Danley

Yorkville has a new Synergy Line. Looks to be a solid replacement to the me too speaker on the stick type setup.
A deployment of 2 stacks per side is needed to get 90* output.

https://youtu.be/eE2KuBXPI0c?t=180 (https://youtu.be/eE2KuBXPI0c?t=180)

So it's gonna be a significantly bigger investment - both in cost and transport/logistics -  than a simple 'top on a stick on a sub' set-up. It will likely have substantially more output as well.

They do show a graphic with one stack per side, but I can't think of a venue where that would be suitable (45* coverage?).

They are claiming subwoofer response of 130db measured C weighted, +/-3db down to 31hz, which is actually pretty impressive if accurate.

I have no idea of pricing but with the licensed Danley tech and premium componentry I'd guess it's well above Yorkville Elite level. I'm curious what their intended market is for this, the video seems to indicate they expect it to scale from a small venue to arena just by adding boxes and flying.

Well this is definitely an interesting new contribution to the market.  The first few thoughts that pop to mind (in no particular order):

- The height of the subs rule out transportation in a standard utility van (standing up).  They would mandate a truck or trailer.

- The weight of the tops is too much to be safely lifted by one person if stacking on the sub, and pole mounting is not an option here.

These two factors combined place the system logistically beyond the SM80/TH118 and Noesis/Orbit Shifter level - arguably two of the top-level SOS rigs currently on the market - either of which can be deployed by a single person out of a van.  I'd be curious to hear how a 1 sub/1 top per side system would compare to the Danley/JTR options, and if the added logistical considerations would be compensated for by performance.  I'd be surprised if it did, which would essentially place it beyond the average weekend warrior, semi-pro, and SOS provider.  Per the video it would appear that this system is aimed more towards larger deployments, but since they mention scale I think it's important to note that the product's size and weight essentially exclude it from consideration in smaller applications where there are better options available, at least in my opinion.   

I have to wonder where this would place among the old Unity Series and TX Series...  I'd guess in between, but I'm sure time will tell.  Personally, I felt (from what I could piece together from dealers/distributors) that the Danley Exodus Series did the larger level point source quasi-scaling better, but it's not apples to apples either.  Definitely an interesting approach though!

It's neat to see innovative tech moving into a more mainstream product, at what I assume will be prices that don't directly compete with Danley's own range.

I'd be curious about the anticipated market too? Arrayable "high Q" trap boxes don't really seem very popular right now.

Unless you really needed the modularity of this or the coverage provided by just one, by the time you add up the cost of multiple units you could probably manage to afford one pair of Danley Synergy Horns, providing the same coverage from a single box - unless these are a lot cheaper than they look.

I keep wondering about the price point. The tops alone look to be in the $2500-$3500 range each and the subs much more. Time will tell I guess. Maybe they've found some way to cut cost. Still interesting times with products like these coming out.

Right. With 4 tops and 4 subs needed for the smallest configuration that has any kind of deployment flexibility, that's a pile 1,400 lb and  maybe ~$25K speakers. Yet at around 6' tall I can't imagine it deploying well in a ground stack situation with the audience at close range as they'd be eye level with the throat of the top box. I'm surprised there's not a 12" pole accessory, or dummy box spacer. I suppose with the cost of the boxes plus labor and transport, there wouldn't be many small venue ground stack situations as the client likely couldn't afford it.

Some polar plots would be nice so we can see the actual coverage vs frequency.

Post by: Roland Clarke on January 26, 2019, 04:35:14 pm
Polar plots and everything else aside, I think we need some first hand experiences of how they actually sound and whether they work in real scenarios.  Tom is without doubt, one of the really good and influential speaker designers around at the moment, but how much or how little he was involved in this product may never really be known, it may weíll be only the use of his design patent.  If it does sound good, weight, price point and form factor will likely decide if itís ultimately successful.

One bottom /one top, L/R, about 40-50' spread, outside,
angled in to center, live mix, in front of Dynaudio demo trailer @ NAMM.
VERY narrow top dispersion. To be fair, a handicapped demo situation, as unable to drive hard and far.
Did not care for tonality with what I did hear.
Questions of price, performance, and best applications.

The spec sheet said it was 45 degrees VERTICAL and 22.5 deg HORIZONTAL. So you need 4 to make 90 degree coverage Horizontal.

Looks like a kick-butt big club rig, but I doubt it will supplant the millions of JBL SRX rigs that are already out there.....

They do say you can place them on their sides for 45 Horizontal / 22.5 vertical. 2 aside would get you 90 but not sure how the 22.5 vertical would work out as they are trap boxes and without scientific wooden blocks to aim them it could be interesting. Correctly strapped of course. About 2:50 in this video.

I originally thought that too, but here's a pic showing the ~90* array. It's a bit of an awkward implementation, IMO.

Looks like a kick-butt big club rig, but I doubt it will supplant the millions of JBL SRX rigs that are already out there.....

My hope for Yorkville is that is designed to significantly outrun an SRX rig. But I agree that people are probably not going to be selling off their Pro-sumer level rigs to pick up this Synergy system.

I don't think this is meant to be an SRX-killer.  This is another product for which Yorky's idea of market position isn't apparent or obvious... but being Canadian I'm guessing this would be ideal for a show staged at the end of a hockey arena after the game is over.

I can say that at least I'm not.  Heck, I'm still trying to get a few more Unity boxes if I can find them!  Unless this system turns out to be a real dark horse I'd just jump straight up to a larger Danley/Fulcrum/RCF rig when the time comes to move beyond prosumer, but that's just me.

From a speaker designer point-of-view, I can see one glaring issue immediately: That really isn't enough port area to stay linear when the power levels go up.

My own subs have a port area that's around 1/3rd of the driver's cone area at the narrowest point of the port. Driven to 1KW (driver's continuous power rating), there was 2dB of compression. ie, what should've been 123dB came out as 121dB at the 40Hz tuning frequency.

It looks like the Yorkville subs have a port area that's a small fraction of the cone area, so I'd expect fairly large changes in the frequency response as the power levels increase.

Since this is posted in the Lounge I will add my thoughts as a "small potatoes" sound company.
To me, the Synergy line is Yorkville's way to add another "active cab" to grab some sales in that very crowded market.

In watching the promo video the cabs can be used for club work and scaled to fit larger venues.

I have a large (relative to me) investment in Yorkville cabs/processors, mostly the TX series.

Output aside, in looking at the Synergy specs, the sub cabinet measures approximately the same height as my TX9's.  When I put my TX4's on top of my TX9's the horn of the mid/hi cabs are at the perfect height for club / local concert work.  My TX racks are pre-wired and an easy plug'n go set up.
I have not found a need to upgrade in my local niche.

Specs are specs and these new cabs are definitely a step-up from what I have but I cannot justify "side-grading" (which is what it would be to me) to these cabs.

...however, they do look sweet!

Can you tell that much from just a picture? (Serious question, I'm not trolling).

The subs are a self-contained system with built-in power and processing and Yorkville specs a measured frequency response +/-3db down to 31hz so I'd assume that's inclusive of with whatever the cabinet's inherent limitations may be.

What he is talking about is the area of the port-NOT the response, or the processing etc.

I have not looked close enough, or know the tuning, but if the port is to small, then it will "choke off" at higher SPLs, causing the low end response to be not as low as it is at a nominal 2.83V drive level (which is where the response is measured at)

Nobody measures the response at full output. 

This not an uncommon problem.

Everything is a compromise.  As you make the port area large (so it won't choke off or chuff), the length MUST be longer.

So this makes the cabinet larger.

Sometimes a larger size is ok, other times not.  It just depends on what the goal is, or expected performance.

That may be true, but then I really question how practical this would be given that the box weighs ~115 pounds and can't be pole-mounted.  At least other larger options such as the powered U15s, the RCF TTL6A, and various small arrays (QSC KLA for example) have the pole option along with stacking and flying, but without it I see it very hard to use in a smaller deployment.

As I said in my post - a port with 1/3rd the area of the 15" cone caused 2dB of compression, and I wasn't even at "peak" levels.
Shoving lots of air through a small opening means high air velocities = friction = losses.

Ivan covers it in more detail quite well, but it's good to know where these effects are coming from.

Where did that post go from Ivan? Where he said most subs outputs are measured at 1 watt input?  Wasn't it in this thread?  Yorkville did state "measured output" as Measured Max SPL (C-Weighted, Max Hold) 130 dB Cont. 136 dB Peak.  Of course we know what MAX Hold is but it is stated as Measured output. Also how it sounds at those levels will be known I guess at a later date.   :-\

I get what you're saying.

But I guess my thought is that you're looking at from a design perspective, but this system is already a finished product. So if the specs are accurate - yes, that's a big if - then the power compression and associated losses you predict are taking place but should already be accounted for in the measured response.

As an end user I guess I want the the design to be optimal, but more than that I want the system to perform as specified. If it does that without significant negative artifacts from any sub-optimal design issues then maybe it's all good? But maybe not - the sub could sound like total crap.

What he is talking about is the area of the port-NOT the response, or the processing etc.

I have not looked close enough, or know the tuning, but if the port is to small, then it will "choke off" at higher SPLs, causing the low end response to be not as low as it is at a nominal 2.83V drive level (which is where the response is measured at)

Sometimes a larger size is ok, other times not.  It just depends on what the goal is, or expected performance.

Referencing the bolded type above - the specs list a measured response of 130db C-weighted, max hold. My comments are made under the assumption that the method used is valid and the spec is accurate. I admit my assumption could be wrong. And I realize that there is no specification of distortion values at max SPL nor any indication of how it actually sounds at that level.

Edit: Just saw that Douglas pretty much said the same thing.
-------------------

I'll also state that I'm not trying to be a Yorkville fanboy here, I've got no stake in the product and TBH it doesn't look like a good solution for any of my needs.

That probably is a valid measurement, but at what frequency?

 According to Yorkville, the SA315S has a +/-3dB response from 31Hz-100Hz, but they don't mention drive level so that is entirely meaningless.

 They list 136dB max output, but again, they don't mention drive level or the frequency at which they measured that output.

 Loudspeaker response does not increase linearly with drive level, they could have easily picked a peak in the response, meanwhile the actual output at 30Hz could be 10 dB down from that due to port compression and other factors.

 Unless Yorkville is going to publish charts at 1W vs 13000Watts, all we can do is guess what those numbers actually mean.

I made the assumption that the frequency response spec was tied to the Max SPL spec.

But I do see now that I probably should not make that assumption.

Spenser covered this pretty well, but here are the facts we have:
- At some level, you get the specified frequency response, which is actually a pair of -3dB points. I'm sure you're aware of the caveats behind those.
- At the absolute ragged edge (ie, smoke may or may not be pouring out, but you can be sure the limiters have clamped the output in every way possible so the box simply won't get any louder), it'll do 136dB.

I'd bet my last £1 that the frequency response at 90dB and 136dB won't match.

That's my point here. My experience as a designer makes me suspect that the ports will be a source of non-linearity at a relatively low level. The result there will be the output from the drivers will carry on getting louder, but output from the port will start compressing.

Whether that's a problem or not will depend on program material and how loud you're running.

If you visit data-bass.com and read through some of the measurement sections, you'll get an idea of how much port compression can show up.

I heard the first "round robin" session at NAMM last week that included the Yorkville Synergy system.  The one thing that bothered me was the way the Synergy sounded with the presenters hand held wireless mic.  None of the other systems sounded that way with the vocal mic.  I'm not sure what was happening, but something just wasn't right.  I have heard Danley demos and the mics always sounded very natural.  The Yorkville were pretty "seamless" horizontally, and the music selections sounded acceptable thru the system. 

Just a general impression about the demo:  The music showed some strong points (and maybe some weakness) of the various systems.  All were professional and very usable systems.  But again to me, the presenters hand held mic told me more about how "natural" (or maybe neutral) the systems sounded.  I thought the systems that sounded best with the presenters mic also sounded the best with the music in general, and especially music that had a strong vocal content.  Maybe what I heard was how the presenters mic was equalized (and I'm assuming it was not changed for each specific system), but overall the systems I liked the most overall (and there were several) were the ones that sounded the most natural with the presenters mic.

Same presenter for all.  He introduced each system and played a music selection (same music selection for every system) for about a minute on each system.  He then redirected our attention to the first system and a differed music selection was played on each system (again the same music on every system).  This happened a third time with a third music selection played on each system.  SPL was displayed on video monitors in both A and C scale measured from a central mic.  Each system was at the same level with the same music for the "round robin".  The attempt was to have an even playing field.  The presenter talked briefly each time so I was able to listen to the same presenter using the same mic set at the same level on each system three times.  The manufacturers had been allowed to EQ their systems as they desired before the demo began.  A burst of pink noise was also presented thru each system.  I thought it was a very good demo fairly done.

Yorkville never really has made a flat sounding system. LS801p was great at the time but really only made one tone. The paraline boxes. I'd rather listen to them than VRX928LAP rig

THere usually is a method to yorkvilles madness. the 3x15 puts the horn lens high enough  in the air for ground stack. A group of college kids listening to a DJ at the campus bar isn't going to care about even coverage. Buy 4 stacks for the bar at long mcquade and pay for an extra 5 years warranty program and you are covered for the entire life cycle save for someone putting the firehose to them.

Its flyable.

THink about how many JBL or EAW rigs that are still out there hanging in the air pushing close 20 years old.

Yorkville never really has made a flat sounding system. LS801p was great at the time but really only made one tone. The paraline boxes. I'd rather listen to them than VRX928LAP rig

THere usually is a method to yorkvilles madness. the 3x15 puts the horn lens high enough  in the air for ground stack. A group of college kids listening to a DJ at the campus bar isn't going to care about even coverage. Buy 4 stacks for the bar at long mcquade and pay for an extra 5 years warranty program and you are covered for the entire life cycle save for someone putting the firehose to them.

Its flyable.

THink about how many JBL or EAW rigs that are still out there hanging in the air pushing close 20 years old.

If this had of been available when I was doing gym size DJ events it would have been very attractive

I measured the Ls801pb and they were flat within their bandpass. The 6 db down point was exactly as Yorkville stated at 45hz. In these photo you can see the sub set for loud and deep.  Deep gives a boost at 53hz.  I had the high cut set to 120hz at the time.  With a little eq I could get a respectable 6db down point of 38hz. (2nd photo)  I often wonder if in the designed market most just ran the sub too loud and thought it was boomy.

From a speaker designer point-of-view, I can see one glaring issue immediately: That really isn't enough port area to stay linear when the power levels go up.

My own subs have a port area that's around 1/3rd of the driver's cone area at the narrowest point of the port. Driven to 1KW (driver's continuous power rating), there was 2dB of compression. ie, what should've been 123dB came out as 121dB at the 40Hz tuning frequency.

It looks like the Yorkville subs have a port area that's a small fraction of the cone area, so I'd expect fairly large changes in the frequency response as the power levels increase.

I would like to point out that while the port area is small compared to the cone area, the total port area of the trio 15" box is not too small for 130 db @ 30 Hz. There are plenty of single 18" 130 db @ 30 Hz subs that have almost as much port area as this trio 15 box. So one can make the argument that this is not the most efficient design. So what if the woofers are not pushed to their theoretical limit? Ports and excursion are usually the LF constraint anyway. Like Ivan said, design trade off. Maybe they can use lower power woofers to save weight and cost. Box size is sort of determined by the top speaker footprint and listening height.

Are you sure?
If I had to guess, I'd say the port area is about 45" x 2", which is less than double the port area I was using for a single 15", and getting 2dB of compression in the low-120dB range.

I do agree with the rest of your post - all designs are a compromise, after all.
