The 3677s were delivered this morning by FedEx Freight. Man they look big and powerful...the finish was very surprised being it's a Pro speaker...it's much better than many speakers i've seen on the "pretty" consumer side of audio.

Within 15 minutes I had my Rockets moved over and the JBLs in there place. I placed a 3677 in each corner toed in about 45 deg (aimed a few feet in front of theater seats) If some aren't familiar with aiming this extreme it's done so the side seats are slightly off axis from the speaker on the same side as that seat but the one across the room is now on axis but farther away..it supposed to help equalize the volume when sitting to the sides. For now everything is on the floor but this still puts the tweeter quite high as these are large speakers. The center is aimed up slightly.

I ran some bass heavy music through them to give the woofers a quick breakin...as MK stated his 3622s sounded weak in the bass for the first few minutes. The 3677s were the same....the loosened up after just a few minutes.

I then used the test tones in REW to see how they sounded down low to help me decide a xover point. At 35hz the were shaking the freaking room The sounded like powerful subs, down to 35hz that is. They roll off at 45hz but I'm getting some nice room gain.

YPOA (Yamaha's room correction) set them to large of course, but I set them to small and YPOA recommended a 40hz xover....I decided on 60hz to let my dual 18s in an IB earn their money.

The bass in Dark Knight and Iorn Man 2 is freaking awesome..it sounds smooth deep and natrual. The vocals are outstanding easily the best I've heard in my room. The overall sound is oustanding yet effortless... with my XPA-3 pushing these 99db monsters my system isn't breaking a sweat and I have gobs of headroom.

These puppies Image great..similar to the Pro-10s yet I don't feal any fatigue during intense action scenes as I did with the Pro-10s. (It was slight with the Pro-10s but it was there possible due to HOM). Everything is super clear and detailed and maintains it's seperation even when the action is crazy.

This of course is day 1. I still have a bunch of demoing to do before I begin fitting them into my wall and mounting them in the corners. So far I'm more than happy.

Tonight we'll probaby watch Shutter Island in BluRay..we haven't seen it yet.

So far so good. Keep us posted. How is the sound stage? My pro speakers are much bigger sounding than any other I have used and combine that with the vocals, dynamics, and clarity they are hard to beat for HT. Do the 3677's provide that huge sound as well?

These horns aren't as large as your old 3622s but being designed for theaters with 200 people in them....yea the soundstage is huge...it's wall to wall seamless sound.

That is what I thought. Do you notice any HF rolloff? I know it is early and the woofers will loosen up a bit more as well.

The high end sounds fantastic....super detailed and super clean.

I have the "Book of Eli" Playing at the moment....I heard the shootout scene in the old western looking town...The gun shots sounded so real it's freakin nuts..the dynamics are crazy...and so is the low end kick!

IT has been hard to explain the detail and dynamics of these type of speakers without the harshness associated with some horns. Most people assume that the awesome detail is from a bright speaker which is a bad assumption.

I was going to buy three of these before I "stumbled" across the 4622's.
Mk (James) has inspired alot of us to step up to real cinema/pro speakers. I would never go back! Congrats!

Cdy2179, do these 'project' the sound out into the room similar to how you described the 8340's when you tried them out?

The 8340a's were great with vocals...the 3677s are better....they should be as they're mains and the 8340a is a surround. I found the 8340a to be harsh...but the 3677 doesn't have the slightest bit of harshness.

Last night we watch Case 39. The Bluray of Shutter Island wouldn't play (bad disk). Case 39 has a bunch of shock scenes, a dog bark or loud knock out of no where... the 3677 made you almost pee yourself..my wife was a wreck Man the dynamics are hard to describe...everything was in your face and sounded very real.

As for the question about the 8340a for surrounds. If I change surrounds I'll probably try the 8320...I'm not too fond of the CD in the 8340a.

I know we have talked about detail but can you comment on the detail? I was told that cinema speakers don't have the resolution of audiophile speakers so I was talked into a different route. I still had the urge to try them so I bought the 3622N's. After hearing them I thought they had more detail than any other speaker I have owned so I have always wondered why dealers say what they do. There is a misconception out there that audophile speakers have better resoultion than pro speakers in general. All pro speakers are not the same. I just wanted yout take.

There are cheap Pro speakers out there that have give horns and Pro speakers a bad rap. KLipsch for one isn't cheap but even they have been found to be harsh and fatiguing by some.. (me being one of them, only the RF line..really like heritage and ultra 2s.). Having heard and owned RF's and other Pro-like designs...I too felt this way and thought horns weren't for me...man was I wrong.

These JBL's have very high quality drivers... the detail is superb with absolutely no harshness or brightness..I also own Paradigm and Rocket 850s...the rockets are awesome speakers but nothing I've heard on the consumer side comes close to the dynamic and detail of the JBLs.

I've only had these for a very short time so this is an early answer but, That's my take on it

I understand it is only one night with them. The only problem I can hear with these are that they are very detailed so bad recordings will sound aweful. A bad recording can come from anywhere.

They're meant to be placed behind an acoustic movie screen...so no grills!

The look just like they do in the picture below.

Congrats on your new speakers! Looking forward to hearing more of your experiences. I loved your comment about your wife being a wreck. My wife says she can't handle the sudden "out of nowhere" stuff. Both of us are constantly jumping out of our seats. It's all fun!

I know what you mean. My daughter (16yrs. old) is a big Harry Potter fan. Read all the books and has watched all of the movies several times. So many times that she can recite the words. She popped in a BD of one H.P. film and had the volume set at -20db. Early in the movie during the scene where the Death Eaters? attacked a person in the tunnel she jumped and screamed. I had implemented a new house curve on the subs using a Yamaha YDP2006.

CDY, I forgot to add congratulations on your new speakers. Glad that you like them. Always nice to see another join the dark (pro audio) side.

I was worried more about "protection" of the speaker itself. It does not look like it has anything that can push in by lets say a couple of cats. The speaker itself looks pretty bullet proof.

Hey, isn't it funny that around hear you get a set of great speakers and people congratulate you as if you just had another kid? That's too funny.

Having speakers like these really opens your eyes to just how little some people around here really know...you see so many people saying great music speakers make great HT speakers and there's no such thing as speakers that excel at one vs. the other, it should be great music speakers may be great movie speaker and vica verca...escpecially in the consumer side. Just like all those people that think real theater speakers won't work in our homes....blah, blah, blah. I used to think the same thing. until about a year ago.

Well, my wife agrees...these are staying..we just disposed of the boxes they came in. I normally store everything upstairs but the boxes are just too big and I don't see them going anywhere.

The Rockets have found a new home in my living room.

The're very rugged but they have a very nice finish...it kinda has the same finish as the horn does...slight texture.

The ports are about 3" deep but they have black foam flush with the back edges, keeping anything from being put in the enclosures...foam plugs would have worked well on the Pro-10 to hide the white stuffing some complained about.
