I should add that I've only owned the 8340a and 8330a. Both were quite bad IMO, probably worst speakers I've owned. The others I haven't had in my room to demo. I have not heard the ones you mentioned.

As for the "wat". If that's referring to timbre matching they aren't even close. None of the drivers are the same.. not even close and sound worlds apart. To even be slightly timbre matched you have to use very similar if not identical drivers. To really be timbre matched they have to be completely identical speakers, all with room treatments that handle reflections in a similar manner to give a like response at the seats to keep the timbre in tact. There's a lot more to it than just using the same speakers but without that .. good luck. That doesn't mean it's not enjoyable. My HTM-12 aren't identical to my 10 volt 10lx speakers.

Timbre differences are easily audible while playing pink noise while at the MLP.

As I said above I should have clarified I was speaking of the surrounds I've owned in the 8 series Cinema line often matched with the 3 series and screen array cinema speakers. I've owned the 8340a and 8330a. The volt 10lx is far superior. I'm not sure about the SCS series, I haven't owned them but have heard good things.

It would however be a major issue to have a 3677 as a left channel and a home speaker as a right. However, having said that, there is a big difference in sensitivity from the 3677 to an average home theater speaker. You will likely have a volume level difference of around 13db. You will likely never run your 3677 past 5 watts if your within 10 feet of the speaker. check out this website link to crown audio to get an idea of the the power levels you need and the difference in output between two different sensitivity rated speakers. http://www.crownaudio.com/en/tools/calculators

When the 3677 will arrive (as center) I plan to use it with 2 svs ultra bookshelfs as L+R , which are 87db , all with Denon avr 2313, no external power amp(-which I understand its not needed).
do you think its a problem, I mean the part you wrote about volume differences ?

You'll use trims in the AVR to adjust for the sensitivity differences so at the seats their levels will be the same. The only issues would be if you cranked it loud enough to run out of power for the SVS. The JBL would remain crystal clear as it doesn't need much power at all but the SVS wouldn't have enough to keep up nor could it even if you had an external amp as it can't handle the power to keep up with the JBL even if the JBL remained on the AVR. Remember the JBL will require 10x less power roughly. Under moderate level listening you'll have no issues.

I never listen at too loud levels. even with 3 svs ultra as LCR the denon didnt seem to run out of air at higher volume and the sound was great. I guess that with a more efficient center the work load would be even better. I hope.

The local JBL rep informed me today that in about 2 month the 3677 will arrive ahhhh, the wait...

I typically listen to movies with dialog at about 67-70db. Every onece in a while i will go as high as 75db for dialog. My speakers rarely go above 90-95db peak. Subwoofer with low frewuencies needing eq to sp0ound equal to speakers volume will be over 10db higher at the lowest octaves so my sub will hit over 100db sometimes. So if you listen like me, you will rarely see the jbl 3677 use more than 2 watts. A home speaker with 88db sensitivty in my system would require 31 watts to have equal loudness to the 3677 at 2 watts. So like cdy said, if you listen loud, the home speakers could run out of gas. But yeah, set avr center channel to -10db, then set left and right channels to +1-3db as a base, then just make sure they are all equal loudness at listening position.

I bought mine online from a company called performance audio in utah. But to my knowledge JBL makes the 3677 to order which means no dealer inventory. Hopefully people can still buy them for a while. But jbl may not be making the 2035 anymore. If thats the case,they wont be able to make the 3677.

JBL actually makes them in batches... not to order. They just don't have warehouses full so often you must wait for the next batch to come off the line to get them or you may get lucky and the current batch may not be completely spoken for. The first time I bought them I had them in 3 or 4 days.. the 2nd time about 2 weeks. It's the luck of the draw.

You can also get them at full compass. Price should be around $600 or a tad less drop shipped from JBL.

My supplier said they still are, but I think this will be the last production run. It appears its the end of an era. It was a good, long run.

I do like the idea of the new line array's coming out for smaller theaters. Those could be some great alternatives.

Highlighted by @MICROTECH85 , the 3677 is officially vintage. It's no longer listed in the Pro Cinema 3000 series site.
It's weird that the 3678 is still there.

How will three 3677s as LCR work just off the floor (sound isolation), roughly 12' from listening position?

(And any thoughts comparing to Klipsch RP280 with matching center, surrounds, and upward firing Atmos.)

Mine work *perfectly* like that. Set so the centre of the horn is at ear height and 11.6 from the MLP. Every day they put a *huge* grin on my face.

Has anyone actually had occasion to hear the new JBL 200 series replacements for the 3677? If so, what did you think as compared to the 3677?

I don't think anyone here has them or has even heard them yet. I believe Mark Seaton was saying their desgin required even further imaging requirements than the previous generations. Are you looking to go with JBL Pro Cinema? I am selling my 4722n with the upgraded CDs. PM me if your interested, I can bring them to Dallas. I am in San Antonio

Unfortunately I only have 12 inches of depth behind my screen or I would likely already own your 4722s. I ended up with three way Klipsch heritage speakers over the 3677s (was tough decision) just because I was curious to try horn mid and horn tweeter LCRs.

I have the Quartets and I like them alot for LCR. I cross them at 80hz so no need for larger Forte/Chorus. If I had more room behind the screen, I'd try La Scalas for LCR but with that much room back there, I'd probably also would have long bought JBL 4722s and been happy with them.

Saw your room plans..looked like you have them off the floor on blocks. I don't have the ability to do that, they need to be directly on the floor. If that won't work well, will be looking into a Klipsch RP system (280, 450...).

Yes I have them mounted so that the centre of the horn is level with my ears when in MLP. But if I stand up or sit down, I hear very little difference TBH so I am not sure how critical this is.
