I was looking through my closet the other day and found a 2425H driver.
How suitable would this be for a hi fi application?

JBL used them in the 4430 and their flagship of the day 4435 studio monitors so I would say "quite suitable."
If we knew what the hell we were doing, we wouldn't call it research would we.
Hi Ivica,
Because of that bad post, my list is: 4x 2225 badly reconed, 1 needing the spider re-glued...
2 x 2470 phenolic diaphragm
4 x 2307 horns
2 x 2308 lenses
10" & 2405's to get and I will construct my own networks as per 3143 schematic.
Now this damn modem has me worried. maybe just keep my posts short.

Hi DogBox,
may be with 2 x 2225 per box, 10inch mid-bass is not 'a must', but 2405 is.
Owing to, using two bass some ideas from 4350/4355 or Everest II D66000 would be well-come in creating cross-over network, especially for bass and mid-bass region (say below 800Hz), and for over 800, 3145 is good example....

Hah! No problem Steve. It's all good info being exchanged.
Thanks for the tip. A pair (with 2344 horns) came up this week on fleabay and were gone by the time I got home from work to take a closer look! Hot little items, apparently! I'll keep looking, I suppose these things come up pretty often.
For all you JBL horn experts, is the 2344 better/worse than the 2370 for home hi/fi application?
Better I would say and I have both. There are far worse horns than 2370's however. Sometimes you can find 2370's for almost free, 2344's are showing up less often and command higher and higher prices it seems.
If we knew what the hell we were doing, we wouldn't call it research would we.
Hi Ivica,
4350's are too big for me! 4343/4344 will be plenty for me to play with!
So, the 10" IS on the list as well... I just have to be patient- they will come....

... as the 2344 is not so easy to crossover prperly.

But they do show up.

Hi Ivica,
For double 2225's, the JBL PROFESSIONAL ENCLOSURE GUIDE suggests 'for general purpose low-end': 8.0 cu.ft. (225 litres)
The 4343, going by the spec sheets, (incl. Midrange Chamber) is: 6.0 cu.ft. (170 litres) ..so for comprison..
the 4345 has a total of 264 all up [but using an 18"] and the 4350 low frequency volume only (2x 2231H) is: 9.5 cu.ft. (265 litres)
Did I mention that the 2225's that I got were 2nd hand, and (VERY BADLY!!) reconed? Not the sort of things to show in a cabinet
without grills.. [and you'd be too afraid to take them off if you had them covered!]

Hi Steve,
Here one thing has to be aware, so called 'mutual coupling of two nearby bass drivers' has to be included in the calculation,
so I believe that more deeper box then 4343 would 'easily' reach about 200L what would be , on my opinion, OK.
Unfortunately most of the box-calculation programs do not include such drivers coupling.
Regards
Ivica
