Re: Danley Jericho 2 in Saint Marteen
So a little bit more information on the Jericho line. This is intended as informational-not marketing.
The inspiration is based on the fact to nobody will argue that a single box will always sound better than multiple boxes (due to the interference) line array-point source etc.
The problem is that in many cases, in larger rooms, a single box will simply not get loud enough or have a wide enough coverage pattern to do the job. So we have had to use multiple boxes to get loud and wide enough.
Of course the problem with trying to use a single box is the high freq. It is relatively easy to get the lows to mids to combine for more output, but the real issue starts as you get higher in freq. Getting the higher freq to "play well together" is not an easy thing to do-since the wavelengths are so small and the physical size of the drivers to reproduce those freq is large (as compared to the wavelengths involved.
It is how to combine the high freq that has eluded designers over the years. Various methods have been tried. The old way of combining drivers in a Y configuration has produced a louder output, but has not yielded good summation. It was louder because of the increased power capacity of the additional drivers, but the response was not as flat as a single driver (due to the incoherent combining). So the effective output was not as much as one would like.
In the Jericho production, most of the time has been spent on how to combine the mid to high freq well. Tom’s lens ideas are what make this all possible. Without giving out the “secret sauce”, the whole concept is based on wavelength. Each Jericho uses a very different lens-based on the limitations and physical sizes available in the different products.
The original Jericho (JH90) was designed as a standalone full range product that sounds great and gets loud. The evidence is the use of this box in a good number of stadiums this last year. In one case a SINGLE JH90 is covering a 34,000 people stadium. No subs are used. The subs that were replaced were 4 6x15” horn loaded subs. The single JH90 has more low freq.
In several other cases a pair of JH90s are used to cover stadiums a good bit larger.
The J2 was developed because many sound companies already have a pile of subs and they wanted a “mid/high” box and didn’t want to buy subs when they already had some. So while the J2 has a -3dB point around 60Hz, the intended usage is 100Hz or so and up.
The J2 driver density is quite large-with 6 woofers-24 midrange and 12 high freq drivers. You can drive the cabinet with a single amp channel (we typically use a LabGruppen 14K bridged to drive it) or quad amped (3 way). So 2 channels for lows and a single each for mids and highs.
The 90widex60tall pattern covers a large number of gigs. The OP is evidence of that. The large horn (the whole mouth of the cabinet) provides pattern control without pattern flip down to around 100 Hz.
The J3 is a higher output cabinet that is smaller/lighter and a narrower pattern-60x40. While it is a 4 way cabinet, it can be driven like the J2 (single channel or 4 amp channels 3 way-mid-high/high is passive).
Generally a pair will be needed for most shows. This would give up to 120 wide coverage. If narrower coverage is needed, the cabinets can be “toed in” with very minimal interference (just a shallow wide dip in the response-rather than deep notches)-due to the fact that each source is well behaved.
Of course all of this would not be possible without the advent of high output high freq drivers that are physically smaller than previous models. The BMS drivers are a big part of the success.
None of the drivers in any of the Jericho models are custom to Danley. By using off the shelf drivers, it makes repairs easier if needed.
I hope this helps shed some light on the cabinets

Re: Danley Jericho 2 in Saint Marteen
Good post Franz. Are you still running all TH-115's as your sub of choice or are you starting to upgrade?

Re: Danley Jericho 2 in Saint Marteen
Ivan, what is the status of the self-powered J1? It is listed in the new price sheet...
Also, I'm toying with the thought of purchasing a pair of J1's, but there would be some gigs where my SH46's would be better suited to handle the top end, due to size/ceiling height issues, but where I could use more sub than I currently have. I guess in that case I could roll in a pair of J1's and use them solely for subs...what are your thoughts on that idea?

Re: Danley Jericho 2 in Saint Marteen
Jack, My addiction to quality musically loud sub low end is probably the reason why you recognized I spent more time on the sub than the J2. While we are on the subject of subs, I realize a long time ago there is a huge misconception out there as to what real bass is.
I don't know much about the internal details of the J2 but Ivan already shared as much as he possible can, it Is better to attend a concert or Demo to get the real feel of its capabilities totally depending on someone else review will always leave you wanting for more, I highly doubt the Danley guys would turn you down if you wanted to dirty your hands on it.
The Jerichos reminds me of LA Acoustics's Vdos box when it was first presented to the public several years ago; armature reviews like mine did nothing to get it recognized.
One of the J2 qualities I like is it's type of loudness, I think all the other leading manufacturers (D&B, La Acoustics, Nexo) seem to be targeting this type of loudness, smooth and easy loud not ear hurting.
Regards,
Franz

How is the going Reggie?
Correct I am still running TH-115s, the DBH-LC will not be ready for shipping until early January from what i was told.

Re: Danley Jericho 2 in Saint Marteen
I can't say why the powered version is still on the spec sheet. There is no way to put an amp that can "survive" the pressures inside the cavity. We are looking at having a "strap on amp" that hangs off the back side. There are several of those in Europe that seems to be working fine.
We are also thinking of making a J sub-which is the JH90 low end and no mids/highs. Just for people that need more low freq. So that would be an option.

Re: Danley Jericho 2 in Saint Marteen
Ivan was right about the sound pressure inside of these things. I filmed a demo near their offices and was way impressed with the newest Jericho 3 Horn. I may be mistaken but I think someone said it's output is higher than the previous J's. However the low freq's are not. They used a TH812 for lows and fed each box one channel of a Lab Gruppen. Here is what I believe is the only HiDef HiFi stereo vid of this latest and could be greatest speaker combo to exist. My stereo microphone has never before buckled under high SPL before this demo and I regularly film loud live bands. All I can say is WOW! Enjoy. Danley Sound Labs - YouTube

Re: Danley Jericho 2 in Saint Marteen
Wayne the J2 Is a 42 driver loaded box, would you know how many drivers are in the J3 and the numbers per mid, low mid etc? Thanks

Re: Danley Jericho 2 in Saint Marteen
The J3 has 6 15" woofers-8 6" sealed mids (the same ones that the JH90 uses-only the JH90 has 6 of them)-and 4 coax mid-high/high drivers. The pattern is 60° wide x 40° tall.
It is a quad amped- 3 way active cabinet. 2 channels for lows-1 for mids-1 for highs. There is a passive crossover between the mid-high and high drivers.

Re: Danley Jericho 2 in Saint Marteen
Thanks Ivan, late last year you or Mike mentioned Lake/Lab Gruppen would have Danley presets for the Lake controller is this avilable now or is it still one of the many projects in the making?
