The fact is that the interchangeability is in the JBL Authorized Service Center Manual....and is accepted by the factory....otherwise it wouldn't be in there. Miss Orchid(Giskard) and Lancer obviously have past and somewhat current ties to the factory, and these two gentleman point out the differences of the interchange as well. UNFORTUNATELY....there are Authorized Servicers that haven't bothered to read the manual and find out these details for themselves and figure anything with a 4" voice coil can be shared throughout the JBL family of drivers. There's plenty of good accurate info in this forum for people to peruse that has come from JBL factory documents....Zilch has some very good points about the availability of some of this stuff and what can be accomplished as long as you have good info....and the right pieces. There's an idiot at anywhere and anytime that will tell you what you want to hear....so those that know here will share here....I've seen it....and I've learned, also.Originally Posted by boputnam

For a while, when Dave owned it, and still cared about the buisiness, it was good. But the last few years, Dave would always complain to me all he wanted to do was retire. Finally somebody bought the buisiness from him, and that was that!
It was also the end of the shop altogether!
I called them once last year, I asked about 2240 recones, the guys say he can get them brand new! Really, you dont say? I also mentioned JBL doesnt make the 2240 anymore! he tells O YES THEY DO! Calls me back a day later to tell me, NO They dont, you were right! BUT, he says, I can recone them. Ok, how much? $350.00!!!!! Ouch, WTF? Well, brand new recone kit with TIT-TAHN-YUM dome he tells me! What? TIT-TAHN-YUM dome? What dome, this is a woofer, not a comp driver!
I just hung up the phone!
P.S. Sorry for the thread hi-jack!

Thanks Zilch
Without the normalization you can see what's really going on. None of them loose that 30Hz although the E-140 hybrid has the most real loss from 30Hz and up. The 2234 would be heard to loose the most lowend when actually there is a 50Hz and up increase in sensitivity without the mass ring. You can clearly see the predicted change in balance with the E-140 core and a 2235 kit. Damn I guess this software really does work!!!

Rob,
Here is the correct expression of the T/L posted here:

Red is stock 2235H, Green = T=1.35*M and updated parameters it effects on the normalised response.
No, they are ebay shots. I just don't know if the seller really knows what it is with no foil.Originally Posted by Robh3606
Yes, you can see the tilt with the more powerful motor as would be expected. Some people won't care. Other people will. I personally did not like the sound of the hybrid in the 4430. I guess my point is that one can do it right like David intended or one can do it however the hell they feel like doing it.Originally Posted by Robh3606
BTW, using BB6P check out the difference in recommended loading between the stock 2235H and the hybrid.
According to Keele, the stock 2235H should be maximally flat in a 4.5 cu ft volume tuned to 29 Hz. The hybrid should be maximally flat in a 2.5 cu ft volume tuned to 35 Hz.
