It's vocals are far superior and powerful. The main thing I did notice was that the Pro-10 extends higher..which is nice. I've EQes the JBL up a little in the treble which has satisfied me there.

I said SHO-10, not PRO-10. The SHO-10's woofer is capable of appx. 4 dB in higher output than is the PRO-10's woofer.

That won't automatically make the SHO-10 "better" than the PRO-10, as there are other differences that we won't discuss in your thread about JBL's.

That's my goal anyway. The thing I find most amazing is that I can put together a good JBL pro system with some Wyred amps, and spend for lees than I would on "high end" home theater equip and have the best setup for my needs. This forum has been a huge help to me in that respect, as I would never have been aware of all my options without it.

I like the way you think! I use a d-sonic with my 4622n's. I guess at 4 ohms it is 1000wpch, just perfect.
If someone isn't using an AT screen, these JBL's are really outstanding:

Now that they are discontinued they can be had for roughly $1500 ea.
They use a 2226 nad 2431CD.

I was actually checking out an online store that has the 4622n for a smokin deal right now and talked to the owner of wyred about power. What have you compared your setup with the 4622 and Dsonic amps to???? How large is the room, and are you completely satisfied??(or as much as one could be).

I really woudl like to pull the trigger on this stuff, just trying to make sure that I am choosing the right combo..

Go to Pi audio and ask Wayne. He is the JBL Guru with this stuff. Here you'll only be getting ideas...he knows this stuff like the back of his hand. He may even be able to set you up with a crossover.

http://www.pispeakers.com/misc/pcb_gasket_outline.jpg

this is the impressive Xover for the 4pi.

Unfortunately no it is not the 8ohm version. I was hoping to swap it out but the more I think about it, I don't know if my receiver will even support an ohm speaker that high so there may be an issue. I emailed Wayne for some advice.

Update!!!

Well I take back all of the nit picking I did with these babies. They really take a while to break in...even the CD has changed drastically. Dynamics are incredible of course but the horns have really opened up.

this weekend we watched, From paris with love (Blu-ray), Splice (Blu-Ray) and Defendor (HD rip). All great movies..especially Defendor and From Paris with love, which had great soundtracks and lots of action.

This is by far the best my room has ever sounded....no longer any harshness..we even cranked it louder than normal and it flat out rocked. Vocals were oustanding, we could make out conversations that were going on in the background of the movie as if we were in the room..things other speakers I've had wouldn't have made clear.

I also experiemented with different horns (primarily the one the 4 pi uses) although the 4 Pi horn did sound a little better with music the original horn imaged better and blended better with the woofer with vocals.

All in all I say for the price the 3677 is total winner...for all I know it's still breaking in but it's already killing anything i've had in the past.

This weekend I built the corner cabinets for the mains and this afternoon i'll be installing the drivers in their new home.!

Well...as often as you change speakers you may be a little crazy.. in a good way.... of course I'm not far behind you....5 different speakers have been in my room in the last 18 months (Paradigm Titans, Klipsch RFs, Rockets 850s, Pro-10s and now the 3677s)

But seriously...for people with acoustic screens and the prices these sell for it's crazy to buy anything consumer. Play a good action packed movie and these things just laugh at my other setups I've had which were "considered" to be decent quality audiphile gear.

I consider the SHO-10's the little brothers to the JBL pro gear. The 3677 is the smallest cinema speaker they offer.

Sounds great! Are your comments regarding the 3677 as you purchased it, ie. you are listening to the original speaker in it's original cabinet, etc.?

Yes the 3677 as sold by JBL. It has really taken a while for it to break in. I've had them for about 3 weeks and they've run for an average of 4hours a day. I talked to one guy who installs systems and he said they sounded as good or better than $20k JBL Synthesis systems he's put in.. he runs 3677s in a multi-row Ht system. I'd have to say I now see why he make such a huge claim.

They've become really smooth and better all around. Better than anything I've personally heard designed for HT period.

I swapped horns temporarily but in the end the stock horn was much better...the CD just needed more time to break in.

Great to hear! I'm tempted! What size of room did you have them in? Mine is 19'x16'. What do you think? I know it's overkill but would they work?

14x 18 open on the side to a sunroom. I sit 15' away. All I can say is tonight I installed the guts into new corner enclosures...after 3 years of searching and trying to finish my HT room..I've finally found my speakers.

Full compass. Cheapest I've found, I even called distributors in nearby states.

They list MSRP but if you call (talk to Darren) the price is $569 each.

I was googling the 3677 last night and some people were putting down the woofer going up to 1200 Hz. They thought it couldn't be very good, but your comments are the opposite. I believe you more than someone who hasn't even heard the speaker. So are you happy with the range below 1200 Hz?

Edit - just read the TCA thread and you say the woofer are ok in that range.

Thanks! The sudden price increase on their site had me worried, good to know that's the MSRP.

I bought complete 3677s because it was cheaper than buying the parts to build them. All along I planned on building custom cabinets for them as I didn't put in a false wall to hide speakers like these. When I built the theater I never thought I'd get this type of speaker. Next I'll build panels to cover them that will resemble corner bass traps when done...it's lookng really nice so far. The horns by the way are outboard...they look pretty much like the JBL 3678.

I still have to install the center into my wall and behind an acoustic screen.

Sorry, you just missed a pair on e-bay for $699. They had the 2226's according to the description. I almost jumped on them when the seller dropped the price from $999.

Yea I talked to that guy over a few Ebay messages back in August..they've been listed for several weeks... they've been relisted.
http://cgi.ebay.com/JBL-3677S-2226-J...01075491433755

The stuff was used (slighlty he claimed) and had no Xover other than one he'd built. After shipping and having to buy Xovers...(It had the same drivers as the JBL3678 so I was going to buy it's Xover and maybe it's horn) I felt the savings weren't enough so I went with new units.

You got the deal of the century Wrager with what you paid for the 4622s..If i lived closer I'd had have the other 3 he had.

I'm debating whether to go with the 3677 or 3678. I like the vertical dispersion of the 3678 better (90 degrees) compared with the 3677 (40 degrees) but it's twice the price........another thought, if you look at the 3678, it looks like the 3677 turned upside down and the horn mounted on top. Could I remove the 3677 horn from the box, turn it upside down, then mount it the same way as the 3678? The spacing between woofer and horn could easily be adjusted I think. Would this get me anything?

Of course you could do that, the gain would be an elevated soundfield versus stock. Then again, you could just put the stock speakers up on some sturdy stands and get pretty much the same thing!

According to Performance Audio, who seems to sell a lot of JBL products, the 3677 and 3678 use different woofers.

Here is a description of the 3677:

Quote:
More information from JBL
The JBL 3677 cinema Loudspeaker system provides natural Sound quality for music and dialog in small cinema applications. The convenient allin- one enclosure requires no field assembly, simplifies set-up, and reduces labor costs. Enclosure design is extremely shallow in depth (292 mm; 11.5 inches), to minimize the space required behind the screen.

The high-Frequency section consists of the JBL 2416-1 pure titanium Compression Driver and 2373 Flat-Front Bi-Radial Horn. The titanium Diaphragm of the 2416-1 ensures natural Sound and reliability, mandatory in today's motion picture theatres. The 2373 Horn provides smooth, even coverage throughout the auditorium.

The low Frequency Driver is the JBL 2035H, which provides an exceptional match for system power handling and Frequency Response in the Crossover region.

And the 3678:

More information from JBL
The JBL 3678 cinema Loudspeaker system provides natural Sound quality for music and dialog in small cinema applications. It can be used in either a passive mode, using its builtin network, or in a bi-amplified system. Enclosure design is extremely shallow in depth (292 mm; 11.5 inches), to minimize the space required behind the screen.

The 3678-HF high-Frequency section consists of the JBL 2426 pure titanium Compression Driver and 2342 Bi-Radial Horn. The titanium Diaphragm of the 2426 ensures the natural Sound and reliability mandatory in today's motion picture theatres. The 2342 Horn provides smooth, even coverage throughout the auditorium.

The 3678-LF low Frequency section uses a single JBL 2226H Driver. This 600 Watt Driver features JBL-patented Symmetrical Field Geometry (SFG) and Vented Gap CoolingTM technology for high power handling with minimal power Compression.

I didn't realize that they had home made x-overs. I agree with you in that case. Good work! I do feel really fortunate having scored the 4622's for almost the price of one! I still think about those two 3732's sitting there in his garage for $950. Arghh...ok, enough is enough.

If I'd had the extra $$$ (almost 2x) I'd gone with the 3678 as it's the same size. the 3677 has the 2035hpl woofer (used in 4622 and several other cinema models). The 3678 has the 2226 which cost actually less through JBL but is supposed to have a better motor structure and considered to be a little better driver. Also the 3678 is only THX if it's run in active mode (bi-amp) with no Xover....who does that...oh yea MK. Anyway If one had the $$$ I say go with 3678...but at that point you could almost buy the 4722.
