In a desire to clean up separate JBL Pro / Consumer / Synthesis / Revel threads that contain a great deal of overlap, I am starting this thread to consolidate the discussion around certain speaker models. Lately there have been so many conversations about such speakers as the JBL M2, the LSR708, the SCL3s and 4s, plus the Revel Concerta2, Performa3 and Ultima2 speaker lines and how they all relate to each other. With all the separate threads it gets really hard to keep all the discussions and Q and A straight. A perfect example is the new JBL Synthesis SCL3 and 4, which are exclusive to Synthesis but share similarities with JBL Pro products like the M2 and LSR7 series (and, in fact, they can be mixed and matched). Another example is the Revel C763L in-ceiling speaker which is often combined with JBL Pro and Synthesis speakers for in-ceiling ATMOS use.

All of these products fall into what might be called "higher end" Harman. For this reason, I often end up cross-posting much of the same information into each separate thread. A duplication of effort for me, and an annoyance to others, yet I want to make sure that those interested are aware of ongoing discussions and comparisons. For example, the other day I posted our listening tests of the JBL M2, LSR708 and Revel F36, and I ended up placing it into three different threads so that everyone interested could read about it. We will be doing much the same with the Revel F208, SCL3 & 4 and the LSR708 sometime in the next week, and instead of plastering it all over the Forum, I am going to post the results here.

So, to be clear, for the most part this is where I will go to answer questions about JBL Synthesis, the JBL M2, LSR7 series, SCL series, and various Revel models that are comparable. I will definitely still check in on the other threads for product specific questions, but will probably refer others back here for comparative or system based discussions.

I hope this new thread helps those who are trying to integrate speakers from these various lines into a cohesive system, and to understand the differences between them!

A hopefully informative first post in the thread - a clarification of what JBL Synthesis is, as opposed to JBL Pro and standard JBL Consumer:

The best way to think of Synthesis is that it is JBL Pro adapted to the home sized spaces. JBL Synthesis was originally designed for professionals in music and movie industries wanting a "Pro Grade" experience in their homes. Synthesis is sold as complete systems, so that Harman can be sure that any “Synthesis” system is fully calibrated and sounds great. Harman personnel design the systems with knowledge of how the components will work together, and they choose the right components for each installation.

All JBL Synthesis systems are calibrated utilizing Harman's “ARCOS” system, which provides state of-the-art room EQ, as well as Harman's exclusive “Sound Field Management” (SFM) and “Auto Curve Sum” (ACS). The SFM algorithm minimizes seat-to-seat variations at low frequencies, while SFM solves the challenge of achieving an ideal blend between the subwoofers and the main speakers. No other system is capable of providing a seamless transition from subs to main speakers, which is immediately audible.

JBL Synthesis dealers like ourselves also sell very high-end JBL models that were previously only really sold in Japan (such as the Everest and K2), along with the “studio monitors” that have long been sold in the consumer channel.

Much of the transducer technology has roots with JBL Pro, such as the breakthrough “D2” compression transducer and its derivatives, as well as the High Definition Imaging (HDI) horn used in the JBL Professional M2, and the new JBL Synthesis models. JBL Synthesis systems are designed for residential rooms—no matter how large—and are optimized for such rooms which are much smaller than the large theaters for which JBL Professional is famous. Therefore, JBL Synthesis truly represents the best of JBL Professional technologies, fully-optimized for residential spaces.

Many “professional” applications occur in smaller rooms, and JBL Synthesis is often found in such applications. For example, roughly 90% of Blu Ray discs are mastered using JBL Synthesis systems, with Revel C763L in-ceiling speakers used for height channels.

You will need to use all Synthesis products IF you want the system ultimately Synthesis certified, which includes JBL techs coming out to your home and personally calibrating your system. Once this is done, JBL will literally sign off on your system exceeding THX and SMPTE specs for accurate film and music reproduction.

Our own demo system is made up of many Synthesis products (mixed and matched with Revel), but since we don't have the Synthesis SDEC, it is not technically a Synthesis system - yet...

No worries, but I suspect this will just end up being one more thread to track, rather than an actual consolidation thread. Such is life I guess.

I don't know how to consolidate these threads, but there is no doubt there is a lot tying them together, which is why John often posts in 3 or 4 threads on some topics.

I think that at a minimum its a good thing to consolidate John's contributions. John has contributed a whole lot to the JBL/Synthesis/Revel knowledge base around here. So if you have a Synthesis/Revel/JBL comment or question, particularly on where these all intersect, then this would be the place to post it or find the answer.

I wish we could have a single owners thread like JTR, but that's possible because the JTR line is very homogenous. The Harman product lines are just too diverse to ever hope for that kind of consolidation.

Thanks Gooddoc!

Yeah, I've tried to think of how to most effectively do it, but other than what I've done here, I don't have a better idea. I will still monitor the other threads, but rather than posting my comparative novels in three or four different places, I will just post them here and link to them in the other threads.

BTW, AVS is going to move the M2 thread from "Industry News" to "Speakers." That should help, too, since many people who might be interested in these wouldn't think to look at the news thread.

Possible they could rename it JBL M2 Owner's Thread since that's why it's become..

So, I didn't mean to be a Debbie Downer, but I've been staying up late taking youtube classes on HVAC theory just so I can talk to contractors about what I want for the dedicated space I am building to house some 4722s, and I am a little grumpy. :)

Carry on.

Hey, you get your side and ceilings done yet? You know I'm waiting until you are all JBL/Harman before I come over :p:). I want to hear your system in all it's glory man. :D
Ready when you are. Come by anytime. @thrang came to listen recently. Think he was pretty impressed based on his recent announcement. :)

Didn't suck...

I hope installing 5 M2's isn't overkill, but then again, who cares...!

I've been curious about the "hierarchy" (roughly delineated by MSRP I suppose) of some of the JBL Synthesis floor standing speakers. My interest was piqued after hearing the K2 at the Newport show - really stunning.

Obviously the Everest is the flagship model, followed by the K2. You then have the S3900, S4700 and 4367 models.

Can you illuminate anything on the differences amongst those latter 3 and how they sort price-wise?

Subscribed, and awaiting John getting the SCL's into the daylight - at least tease us with some unboxing pics John, ahead of your review!! ;)
Yes come on John the pressure is on!!

Just get them hooked up in stereo mode to kick them off as that could quite revealing in itself, of course supported by a couple of decent subs for low end duties.

I await in anticipation.....

I think each thread represents something different. Ie not much overlap
It's nice to have multiple threads. One thread may be discussing amplification, another room interactions, another Dr. Toole's work, another comparing two or three speaker models, and yet another with reports on newly purchased items. Only one or two threads could get very boring (personally to me). With multiple threads, a thread may be boing, but a week or so later it may have great insight into a subject, or be very entertaining.

@John Schuermann puts a lot of work into these threads and that is appreciated. John also has a good way of contributing to the discussions so that they can explore both positive and negative aspects of Harmon products and their use.
