My JBL 4435 quandray

[Odd]

I would not put so much work in this.
You can accept small deviations in interior volume.
You can compensate by tuning the ports.

I have the opportunity to buy a pair of 2235's. I realize the 4435 requires 2234's. But what if I use the pair of 2234's I already have for the mid-range woofer's and use the 2235's as the LF drivers? It seems it makes sense, since the 2235 actually has better LF curves than the 2234. My sense it telling it might be able to be done but may require different tuning (port length and or more damping material, crossover change?) My other thought is to just use the 2235's until a pair of 2234's come along.

So suppose your opinion is that using the 2235 is not a bad idea. What equipment would be required to make such a modification? JBL must have had a good reason not to make this configuration to begin with, I wonder what it was?

Unless the 2235Hs are in remarkable condition at a great price, I'd look for a pair of suitable cores and get new 2334 recones in them. Doing this gives you "new" drivers at a fair price.

LF response of these drivers are identical. The only difference is a rising midrange response for the 2234, because of the lighter cone.
If EQ can be used the 2234 is an all around better driver than the 2235.

Its unscientific and annecdotal, I know, but I originally had a pair of 2235s in my my L200 based 3 ways
(with Giskard's 4333 based crossover) back when I still used the original LE-85s , and when I swapped the 2235s
for a pair of 2234s, they sounded so much better - better integrated somehow.
The 2234s are still in there, by the way ...

For posterity's sake . . . shouldn't that read "2234"?

Well this is where I am at this point. Yesterday I picked up 2-4435 crossovers/L-pads, 2-2426 and 2344's, and he also had the 2235's. I decided to get the 2235's anyway. It was a all or nothing proposition. The crossovers will save me a lot of time rather searching for parts and pieces and the 2344's with the 2426's was nice not having to go to Ebay and hope I got what I paid for. The 2235's while not correct were very nice condition. They were JBL authorized re-cones and look perfect. As far as using a 2235 in each speaker I pan to use it at least for now and if it doesn't sound right and we can't make it right, I'll just keep my eye out for a pair of 2234's. After making the sale I did take everything to Midwest Speaker in Minneapolis and they verified that all was good. The only thing I still need will be the foilcal. I've not seen the 4435 offered anywhere so far. I'll do some searching in case someone has posted what the Pantone color is for the JBL orange. I have one one my lone 4435 but I could be faded. Otherwise I'm waiting on my help to start the cabinet build which should be in a few weeks.

Well- my quandary is over. The mate to my lone 4435 is in the house. My son and I spent all last Friday and part of Saturday and a few hours yesterday measuring, cutting, drilling, routering and gluing mdf. The result is a knock off 4435. I was fortunate enough to locate the crossovers, and all the drivers locally. I swapped out the crossover from the lone 4435 so everything would be the same rev. in case there were any differences. The parts came from a fellow member here. I just happen to run across a old thread here where he said he had everything except the enclosures. His thread was from about 6 years ago, his moniker is Bo. I contacted him and he was willing to part with them, so it moved my project up considerably. I could not paint them or veneer them. We were working in his semi-heated garage with a outside temp of 20 degrees F. I'll have to wait for spring to paint outside.

After just 24 hours I have confirmed that am so glad to have found the lone 4435 and to now have a mate. They are a wonderfully sounding pair of speakers. They do so much that I have never had before. Working backwards from most recent I've had, Infinity RSII's, factory stacked Dahlquist DQ-10's, ADS 910's, Magnepan 1.6's, Magnepan 1.2's, Fried H2 satellites and Freid sub, and just prior to that a Dahlquist DQ-10. that takes you back to 1980.

These best them all by a large margin.

Thank you for all your help and input I am a JBL'er for life I suspect.
