No problem, they look like a damn good surround, maybe even main. But if you have the room and the 3677 being cheaper, it's a no Brainer. They look really cool. You could recess them into your wall so they wouldn't stick out so far....Just thinking.

I have never heard the 3252N, but I would be worried about the crossover. Isn't it pretty high for a 15 inch driver? As others have said, it would be very interesting to listen to them side by side with the other JBL Cinema models.

This weekend, I actually heard a demo with three 3677's in front. To be honest, I think they sounded a little harsh. This was a setup with no correction and the room had some flutter echo, so this is probably some of the blame. But there is not doubt that the 3677's are not as smooth sounding as the HF on the 4722. But the 3677 definately has much of the qualities I like about JBL Pro cinema speakers and I think my audiotion could be improved with some (manual) correction and more room treatments.

My room is treated, that definitely makes a difference, mine were a little harsh until they broke in. Strange though, I found them very smooth afterwards, as did the review by Andrew Robinson and he domoes speakers as a professional having heard more high end speakers than many of us will ever hear. Although he does mention if not set up properly they can take you're head off. I wouldn't dare have these or any of these jbls in a non treated room, and would definitely eq them.

I actually think that this applies to all sort of non-consumer speakers. If you just use them as plug and play and don't use some sort of manual correction and measurements, you will not get a good result. At least not as good as it could be. Pro gear is designet to be corrected and cinema-series for example are designed to be placed behind perforated screens. I believe that QSC takes this into account when designing the crossovers. Don't know about JBL though.

If I were on the market for a single-enclosure passive cinema speaker, I actually think I would look at the new QSC-lineup instead of JBL. They use new waveguides instead of the old JBL horns in the 3677. The QSC speaker: http://www.qsc.com/products/Loudspeakers/DCS_Series/SC-1150/

Those QSCs look nice and I like the slim profile. They cost roughly $1000 for the SC-1150 and $800 for the SC-1120. I had to call around a bunch to find them and get pricing. They are so new that there isn't much info on them out there.

Now, back to our regularly-scheduled JBL thread...

I would stick to JBL myself! For that price we can get 3678's and 4722's or close to it. Personally if I was to get a cinema speaker again it would be the 4670D. How much are they?

Yea jbl is hard to beat and mine were very smooth . That's why I no longer search for speakers, and why I don't have the urge to try the higher end jbls like 3678 or 4722, the 3677s exceeded all my expectations and I know what I'm getting. Now if I could a/b them against some of the others in a properly treated, room set up properly... I may find i like one of the others enough to justify the higher price.

I wouldn't judge any speaker just thrown in a non treated room and not eq'd and say something else is better. Until they are properly set up you haven't really "heard them".

It's kinda like test driving a corvette z06 down a gravel road and saying it handled corners bad and rode like crap.

I couldn't agree more! I have dual stacked DR-250's right now and always wonder what if and recently A/B'd the Yorkville U215's which are considered excellent speakers as well and I am very happy with what I have. The York's have big dual 15's like the JBL cinema but with a Danley synergy horn type CD and mid's.(supposed to be an upgrade over simple waveguides) and my horn loaded 10's did a fantastic job. I could always go to DR-280's for monster midbass and the same overall sound.

Yea, it would be awesome to be able to hear all of these speakers properly set up in a treated room and have a real blind test.

The best thing about blind tests are when you pick the cheaper product. The hard part is letting the expensive and well known product go! If you want to impress people all you need is a popular name. Based on the forums I would have thought the unities to wipe the floor with my BFM's.

Yep that can be hard one to swallow, people who spend thousands on speakers having to accept or often refusing to accept that their 90db fancy name brand, expensive speakers can't hold a candle to these pro designs in a dedicated theater.

Guess it's human nature to think that price equals performance and you've paid for something that can't be exceeded unless you spend even more than they did. In a home theater at least, that can be far from the truth.

I think MK may have done a diy version of something similar in a 3 way design, if I'm not mistaken. It's definitely a beast.

I Put together a 3731. I tried the same woofer in the 3722 rather than the 2226. It was nice but I never had the active crossovers perfect. The nano would make them sing! I could not fit a 4732 but I did have the mighty 4675c-LF . Talk about a monster! I only moved on for more subs because I could not fit anymore with those beast. I wish I knew about the smaller horn like the 4670D, I would have kept them and swapped the horns. That large format CD was awesome.

I want clean reference level playback at listening distance of 12 feet. smile.gif


When ever I read something about some of the other JBLs and think, should I spend more an get more expensive ones, I reread this

http://www.andrew-robinson-online.com/review-jbl-professional-3677-screen-channel-loudspeaker/

And remind myself, This guy has professionally reviewed speakers that cost As much, maybe more, than my whole system. His YouTube video was like he was reading my mind.

But , and it's a big but IMO, they really should be behind a screen to really optimize them. However I was forced to put the center on the floor and it did sound awesome. Soon they will behind the screen in my new theater.

From what I remember going from the 3622 to the 3731 and then to the 4675 was similar. The differences were big sound and mid bass. The bigger you go, the louder and larger the sound. The mid bass gets more impactful adding another robust 15.

Yes the 4675c is considered by many theater installers/tuners to be the best sounding JBL Pro Cinema model ever they ever made. Tomlinson Holmin used them in all of his THX instals that he designed.

One speaker that I never see talked about around the forums is this model from EV.

http://www.rsem.com/equipment-details.asp?partnum=TS940D

It is one of the best sounding theater mains ive ever heard and sounds similar to the 4675c from the rooms ive heard it in. Similar to the 4670D but less power handling If I remeber right. Hard to compare different speakers in different rooms I know but you can get an idea. It has a nice low 500hz crossover and a large format CD. I keep an eye out for a used trio of them although im incredibly satisfied with my current theater mains.

The JBL3677 is a very neutral speaker, it's not bright at all. It will pretty much reproduce what you feed it.

Those are more expensive by about double. I've heard them and they are absolute midbass monsters with a huge soundstage and dynamics. They sound similar to my 4722 hybrids. They are very hard to find too. But if you got the space they won't dissapoint.

The 3677 is an inexpensive fabulous speaker that is smooth sounding with great midbass and dynamics. Like cdy said they reproduce what you put into it and most JBL Pro are the same way. They do not sound bright once broken in. It's hard to find a bettr value to performance speaker for the price unless you buy used. That's the route I went.

I wouldn't take much from thst post. Although QSC makes incredible pro cinema speakers, the 3677 waveguide works great. It's the giant three way cinema mains that require the longer throw distance. The 3677, 3722, and 4722 only need about 11-13 ft of throw to sound great which is about the distance of most peoples first row.

My replacement speaker is on a truck for delivery today. Very happy about that. I also finally got my 50 foot extensions for 3.5mm cable and hdmi. On my day off this week I'm gonna eq each speakers individual response according to this guide here

http://yabb.jriver.com/interact/index.php?topic=87538.0

Any thoughts from you guys if I should eq the speakers and then run audyssey, or vice versa. Also gonna use rephase to generate fir filters. I'm assuming that step should have both audyssey and the parametric eq in the chain when I run it.

My next two upgrades are going to be subs, and room treatments. Been talking to FOH about room treatments, but I wanted others opinions on this too. What will be the biggest improvement in overall system sound initially. Add in the subs (probably an IB install and try some diy flatpacks for frequency smoothing), or do the room treatments first and subs later? It's a living room so no treatments currently, and my current sub is a PSA xv-15se.

Well you won't really be able to even give a worthy review of those without room treatments. They will sound much better and in a blind test you'd swear they weren't even the same speakers.

So I'd vote treatments hands down. For a dedicated theater, I'd vote treatments no matter what speakers you had.

You'll probably find you even like a lower crossover point with those

I don't know about your audyssey version but mine eqs the speaker too, as well as spl level.

As far as Ib . I have an ib with 2 fi 18s. It sounds awesome, but there are drawbacks. My next home theater n the next house I'll soon be building will reflect everything I've learned and experienced over the last 15 years.

It won't have an Ib, I've build my share of subs and multiple 18s in separate enclosures will sound smoother than one or two Ib manifolds, because of course more locations the smoother the room, and they can moved a little to really find the best locations. With an Ib, if the location isn't quite right your stuck with it. Sure the bass is super clean, and it goes low, mine is flat to 5 hz, heavily equalized though. But ported subs just hit harder, and honestly I kinda miss the way they hit in my room. I'll have 3 18s spread across my front stage in my new theater.

Just my 2 cents
