Jbl 4350a 2231a vs 2235 recone sound quality

[JoeNelis]

Hi all

Does anyone have experience in a listening session with regards to JBL 2231a drivers in a pair of 4350's original compared to a new 2235 recone in 2231a baskets' in jbl 4350.:

I have bought some 4350's for a project and as the original recone kits for 2231a are no longer available. I have read some threads here, but just want as much info before I decide to go ahead...... Thanx !!!

Not in those monitors but TMA1's, in all honesty the difference is minimal to the point of being able to put it down to 'new'. The likelihood the 2231a's were optimal before recone is moot.The 2235 cone employs an improved 'progressive spider' so...
Same or better sound.

Thanx for your thoughts, I was thinking along the same lines. I know the 2235 can handle more power, but I have read on the forum that the spiders are rated on stiffness and then can change the sound...my thoughts are I maybe will refoam them and then do a listening session with 2231a in and then I have 4 2235h with new recone kits. I will post the outcome in the coming months :D

Not in that speaker, but I did try some 2235H's in my 4333a's when I had them just to see what would happen. The improvement in bass was not subtle and was immediately apparent. However, in that speaker my opinion was that the 2235 did not tie in well with the crossover(at 800 Hz) and midrange horn and because of that was a no go. Since the 4350 is biamp only and crossed over at 300 I would not see any problem at all, and you will be the beneficiary of the improved bass. Note, though, I was using the actual 2235H,
not a 2235-loaded Alnico frame.

Thanx for the advice, sounds wise. I have four 2235h with full recones that I will try
Am looking forward to the listening session. Thanx again !!! :D
