4355 Monitor Plans

[saeman]

For those interested in building the 4355 Monitor I have cleaned up most of my drawings. I have several more to go and will try to add them as I get finished.

Baffle layout in sililar to that of the 4350/4350B but there are slight differences in the location of the component cutouts. The big difference is of course the single port on each side of the 2235H's. Diameter is 5 3/8" I.D. and finding the correct size tube is proving to be a challenge. JBL used rolled cardboard type material for the duct tube. My detail showing the dogleg shaped tube is only approximate. I will post more accurate drawings when I actually find the tube material and build the duct.

The internal cabinet dimensions are identical to that of the 4350/B as is the gross internal volume. The Mid-Base box also is the same as the 4350/B. Only differences in internal bracing changes the net internal volume.

All of these details came from the only pair I have had an opportunity to open up and inspect. There may be minor differences between models, but I suspect due to the short production run that they are all the same.

I recently located a source for the odd ball sized tube needed to build the dog let shaped duct tubes on the 4355. Thanks Woody for your help. I have the tubes ordered and will have them soon. I can now complete my 4355 project with the assurance that the tubes are exact.

I ordered extras and will offer the tubes, cut and assembled in the proper fashion, and ready to install in the cabinets, to any of you guys who are comtemplating building the 4355 to factory specs. Four tubes per pair, price to be determined after the material arrives and I determine fab time to get them assembled.

PM if interested.

[saeman]

Here's a couple of pics that show the duct port tubes mounted and aligned to the proper angle. Warning - we have 3 cats and they're always poking their heads into my ports when the grilles are off. No problem with 3" or 4" ports but these 5 3/8" ports are big enough that the slippery little suckers could crawl into the cabinets. A quick 100 db burst would likely force a quick exit but I worry about them leaving something inside my cabinets that won't smell too good. I'll likely not leave the grilles off when I'm not around.

If anyone needs help duplicating these tubes let me know. I have extra tube and the info to cut, assemble and mount them.

[saeman]

Here's a few more pics of my 4355 project. The cabinets are essentially complete. My holdup was solved when I received the correct tube for the ports. Cross overs are being built, woofers are being reconed along with new diaphragms for the 2405's. When everything arrives I will get them fired up. I expect the new charge coupled x-overs to take these to a level beyond the 30 year old factory 3155's.

Cabinets are built from the plans I posted and are EXACT duplicates of those produced by JBL. I doubt anyone could tell the difference side by side, unless of course you noticed that they were new and everyone knows that new ones don't exist. Call me anal maybe, but I struggle always for a certain level of perfection - makes the effort worth while.

Veneer is walnut and stained/oiled to a patina very close to those finished by JBL. A ten foot sheet allows a full side/top/side grain wrap which is a nice added touch that doesn't cost but a few more cents per square foot. I'll mount the grilles on the second cabinet, wrap them up and sit them aside til all of the parts arrive.

More later - Rick

Hi Robh3606,

It seems that most of the data are there EXCEPT the "ducts dimensions", so the box tuning is is not defined.

Hello guys, I have read about few people here with great skills making charged crossovers for the 4350 4355 monitors after so much effort I finally got all the components and I'm building my own cabs could you please refer me to someone that can build me a pair of crossovers.? Please let me know, thank you soo very much in advance

Since I can't find it in those beautiful drawings: Side panels, top and bottom are 1" thick, correct?

I built mine some 20 years ago, in an entirely different vertical enclosure, the crossovers are stock 3107’s. I do not know or understand much about charged crossovers but if they offer any audible quality improvement then I am willing to try a pair on my DIY 4350’s as well.

That's very kind and helps a lot, but we need one more number to calculate the dimensions of the shorter piece of the tube.

[Allanvh5150]

The drawing is to scale. Print it out and do some measurements.

Is there any possibility that he still has some of the fabricated tubes left ? I know this is an old thread. Thanks, Jay

Does any one know where to source the tubes ? it the last piece of the puzzle to bliss!

[Odd]

Even if you build with drawings of orignal cabinet there will be slight variations in volume. For exact tuning, you need to make measurements after everything is installed.
The drawing posted above can be used as a good start, make one of the legs longer than the drawing so it can be cut to the appropriate length.
There is a lot of info for tuning on the web

Be happy you chose 4355, in 4350 you have 6 tubes to work with.

[focalguy]

Well, I was lost too but after printing a copy and scaling it from Allan's post it was easy. I should have kept the dimensions as I have closed up the speakers now. Yes building these was fun. The 4351's are next. Sorry about the upside down pic! This is a great thread!

[Challenger604]

Uline.ca! You will find exactly what you need! Overnight shipping!

they say 5" but the outer circle is what it is on the plans posted here!

i did the length posted on the plan but have to build a bit longer. Tuned at 35Hz. Would like to go down to 27Hz or 25...
cheers!

PS! The blue that you see here is the closest to the JBL blue. Could not find the right code due to the fact the paint now is water based.
it may be seen darker. This could be due to the automatic white balance of the Ipad...

JBL 4355 came after the 4350 at the end of 70's. Only 250 pairs have been build.
I read that they are better than the 4350 but I've never heard them.

a lot of info if you google it.

I don't advise on using the 5235 for high quality hifi unless it's has been fully recapped and modernised and if you need specific EQ for the 4355.

While it is a good starting point, the 43's really their potential with something like Bryston 10B, Westlake etc.
I had a BSS 360 (actually I still have, it's on the shelf waiting for a new owner) and it ran circles around a 5235 but then came the 10B and wiped the floor with both. It was also the first crossover I had that I could not directly distinguish it's sound signature.

I just took a look at the japanese audio-heritage website and I am surprised to see that 4350 actually had a higher bandwidth than 4355.
It's stated as 30Hz-20KHz within 3dB whereas the 4355 "only" does 31.5Hz-18Khz.

Hi there!
after 2 days of very intensive work, I'm done with the veneer and trim! A little bit more of delicate sanding and they will be ready for finish. Any suggestion? Tung oil, Danish oil, Livos oil?

Thanks!
the veneer is a sheet 4x10 that I bought from the Woodsource in Manotick, near Ottawa. I think the owner ordered it from Montreal. I think it's a ten mill paper back.

Yes, I used liquid contact cement. I would not use it again. I would use the gel contact. The roller time is very limited.

I used the countertop roller to press everything. Being careful on the edge. I don't know why they don't recommend the roller to press. It works very well!

Over lapping 1/8 would've been enough. I did a 1/4. You just need to be very careful when you place your veneer on top. Verifie that are right on where you are supposed to be. No mistakes allowed!

I used my router to trim the excess...

Yes I used 5/8 for the base of the grills and 1/2 pine for the top and stand offs. Don't worry the garage is heated.LOL!

Thanks John!
is it not too heavy?
Very nice 51's but so sad for the 55's!!
Cheers!

Details to be done but I'm all set!! I will have heat for the winter!

[Challenger604]

Lovely Work! Thanks for sharing the photos.

You're killing my OCD though with the wires protruding the sheet rock beneath the wall rack without going through a wall plate!

They sell split plates that can be installed without having to disconnect the wiring.

Thank you very much for the link but it's one of the details that I still have to do! I will surround the hole with hoak like I did with the rack and because I have two amps comming tomorrow, I have to make an other rack beside for them and my second B77.

I finished the acoustic panels, thinking of acoustic clouds but that can wait...

Has anyone done a metric version of these plans ?

I guess not! JBL=North America!
You just need to convert it or buy a SAE tape measure! Pretty easy! And easier than metric!

Google would do it for you!

You will need all the internals, baffle measurement, as well...

Compare to the overall work on those speakers! Converting the measurement is a piece of cake!

It is a lot of work! Believe me...

I believe you that there is lots of work:D If someone has all the plans converted to metric please share them here.

I saw a video from Kenrick Sound, i believe they use particleboard for the sides/top/bottom. Is the front and back birch ply 3/4" ?

The baffle is 3/4 also the inner box for the 2202. The rest is 1"

I would not used particule board. I would go with plywood.

I was a bit confused when i saw the video, KenrickSound seems to be making quality work, but still they use cheap particle board. What material did Jbl use for the original 4355 ?

Baffel seems to be very thin compared to modern speakers.

They used to use particule board.
The 4350 used to be made with 3/4 with more re-enforcement.

The 4355's were the best Studio monitor back then. Only around 200 pairs build buy JBL. Extremely rare.

Someone had an original mint pair for sale here not long ago. I don't know how much they have been sold but I would think around $35k.

I don't like modern speakers. Plastic, expensive and ugly...

[Voice]

Im not sure what speakers are you referring for plastic/expensive, but there is lots of speakers on the market that are build much more sturdy and vibration free compared to old Jbl speakers.

So go for it and stop wasting my time answering your question!
Good bye!

You seem to have some kind of attitude problem or just a bad day ?

Hi,
I think if using proper bracing and correct absorbing material, and original drivers, the rest would be less important...

Not at all dude! I don't know what you are doing here! This blog is not about expensive plastic speakers.

Move along...

Yes Kenrick is using Particle board for the Outher and back, than using Plywood (not birch! I guess Fenolic or something cheaper....) and inside brace is made by solid Fir or similar (not solid birch)

than they walnut veneer and walnut solid for the front shape.

most DIY project use full Plywood, birch or not, and inside Solid wood. (here on the forum some used particle board...)

I used full birch plywood 1" for every side and interior(let say 24mm, we don't have 1" in Europe), only the 2202 box is 3/4" (or 18mm in my case)

I don't like MDF and Particle board.

Despite the fact that there are many spanish speakers in the World, I'm not able to understand. Even if there are not working well with latin based languages you can try automatic translation tools:

Where I can obtain the electrical graph of these monitors, or where they can be bought?


You'll find it somewhere in this forum.

May I also use my native language :D
