Extra Info:

 

Anyone considering the investment in these speakers know what they are so I won't go on too much of a rant.

 

In my opinion these are the pinnacle of the 43xx Blue Baffle monitors. Overall system sensitivity of 95db/w and capable of SPL's exceeding 126db. Why would you require such high SPL's you may ask? Whilst you are not likely to crank the speakers to a level approaching 126db it's the sheer effortlessness of reaching high SPL's that is so addictive with large JBL monitors. They will play loud without a hint of strain. The dynamics here is just off chops. I have never heard another speaker come close to the mid-bass wallop these have. It's just insane, unless you have heard these speakers you couldn't even begin to imagine what I am referring to. I assume if you are considering these you are familiar with the drivers so I won't go into there sound signature of each but I have to say these are the most dynamic vintage JBL monitor.

 

You may ask where the 4345's fit into the mix? They are a similar sized monitor in size and sensitivity but with a larger 18 inch woofer as opposed to 2x 15's. Well you can keep your 18inch woofer and I'll raise you a 12inch mid bass, but most importantly the 4350's have a 4 inch compression driver and 2inch horn. The diaphragms are more than twice the size of the 4345 and the driver weighs nearly 20kg alone. It makes the 2420/2425 look like a toy. The 2440/2441 is really as good as it gets with vintage JBL horns. It's not just the sheer size of the 2440/2441, it's just a superior driver.

 

All the cones and diaphragms are original JBL OEM and being the "A" variation the drivers are all Alnico. The speakers come with the JBL 5234 Active Crossover with the 250hz crossover cards installed. This is just a freebie thrown in with the speakers but I would seriously look at a better crossover for these. I used a DEQX but something like a Bryston 10B or First Watt B4 would be good too. The old JBL crossovers are a bit long in the tooth these days, even if you recap them.

 

I bought these of the original owner so these have not been passed around or abused. I have the  foilcal for the grilles but the plastic flim has started to peel off so I didn't stick them on. You could heat them up with a heat gun or maybe get on to them with an iron.

 

Cabinets are in pretty good nick, the speakers are now approaching 48 years old so that has to be taken into consideration. If you look close there a few marks here and there but they are a solid 8/10. There is one defect worth noting, on the top left corner of one side there is a bit haziness in the finish. I have hi-res photos with the flash on so you can have look. It's not a big mark but worth mentioning. Unless you had a pair stored in a vacuum I doubt there are many 4350's in better nick. Sequential serial numbers 12007A 12008A. These will never depreciate and along with the Paragon are the most valuable and sort after JBL speaker.

 

I doubt this would interest any buyers but I have a pair of charge couple 3155 crossovers I could include if you wanted to bring these to 4355 spec. Jantzen caps, Jantzen Wax Inductors and Superes resistors. The HF portion of the speakers have been re-wired with Duelund 16AWG and the binding posts are CMC's. For a little extra I can provide a JBL MPA600 power amp to drive the LF section. 400 watts in 8 and 600 into 4, plenty enough to drive the 4x15's.

 

Not expecting to sell these quickly so I will not entertain any low ball offers. If you are local and want to hear the speakers without the interest in buying I am happy to give a few people a listen. This would have to be at a time that suits me as setting these up requires substantial component changes in my system.'

 

Edit I should also add I am open to trades. The speakers I am interested in seldomly come up for sale but it's worth a shot. If you have a pair of Duntech Sovereigns, Sonus Faber Amati Anniversario or Elipsa Red or Stradivari. Let me know.

I've heard these bloody excellent JBL's in action and if I had a larger listening room then they would be sitting in my room not Chris's. 

 

GLWTS not that you should need it.

Yes I heard these too but not in Queensland but in Perth in a studio.I put them against up against Duntech Sovereigns which the studio now has.The pair of 4350 that I heard went to a partially blind man who loves them & would never sell them.So if you love JBL then these are the best but I did also listen to the JBL Paragon around 30 years ago.The only pair in Australia sadly gone to Japan around 10 years ago.

To me the Paragon is not as good but sells for 3 times the price of the 4350.So for $17000 these are a bargain & all you JBL fans & lovers should get as much money together.I am serious when I say these are a bargain

Yes I have been to Poons head where the Duntech Sovereigns are.

The 4350 will play louder then most domestic speakers from production till today.It is a commercial speaker but it is the closest sound to a live concert then any domestic speaker even louder then Tannoys. 

The Duntech Sovereigns are meant for near field monitoring.They can play loud but not as loud as JBL.

ATC is another company who can play loud & be a near field monitor at the same time but will not play as loud even as an active speaker then JBL 4350 simply because ATC does not have 2 15" woofers plus a 12" driver plus horns as this equals more to 115db.JBL 4350 wins in the end.That's why the JBL 4350 is a bargain.

I am curious how you configured the DEQX setup with these.  Did you bypass all the Internal crossovers? Ie speaker and room correction?

 

i use a DEQX HDP5

 

These are way to big for my place

The Deqx is configured in biamp mode anywhere between 250hz-300hz. The LPF feeds the woofers and the HPF passes through an internal 3-way passive crossover.

 

I did try the speaker correction with these but I could never get a result I was happy with. The room correction on the other hand was mandatory.
