View Full Version : Ferrit equivalent to 2410 or 2420

09-30-2016, 01:01 PM
HI, iam just researching today, toying with ideas for a bedroom cabinet, I like a 17x37x12 3114a design,
I read a post as well as watched a video using the 2305 with the 60 dispersion, I liked the sound but it seems distant to me in comparison to the 2105. I was thinking a 2311 maybe neat to try with 90 and 45 dispersion.
If using the 2311 horn id like to keep this cab ferrit drivers could anyone tell me what equivalent I can use to the 2410.
The 2425h is crossed over higher I think then the 2410, an without mods to the 3114a id like to keep the numbers as close to original. The 2426h I believe goes lower. Not sure for sure.
Thank you

I know the 2425/6 would need the smaller 2305 unless I find a adapter, the 2311/24 just plays higher so im in thought it may not be received as a suitable bedroom system ( would a need power to wake these up )

2" horn = biamping?
The sansui qrx 8/9001 will be doing the work here. 100-120wpc. 03 distortion

Dont know if this helps you, but just a short impuls:

You can purchase original 2420 diaphragms and swop them into 2425 or 2426 if Im not wrong.
This way you would get rid of the less pleasing titan diaphragms and your driver should behave very very similar to the alnico 2420.

I know this works for the 2" compression-drivers, so please can someone else verify this for the mentioned drivers?

D8R2421 and D16R2421's are still available from JBL, for how long unknown. D--R2420's are NLA.

Thank you barry & my friend in Germany. Id like to use the 2420 or 2421. The 2410 sounds to forward for a bedroom quarter. Id like to use them in a larger room. So they will not be incorporated into this system

The 2311 has a two-inch threat. All the drivers you mention have 1 inch throats.

So id need the adapter,
I'm not interested in the 1217
2311+2327+ 2410/20 maybe to long
2311+2440/41 Im guessing,

Sorry about the confusion.

So id need the adapter, ...2311+2327+ 2410/20 maybe to long...

The JBL 2307 at 7.3/4" is a full inch shorter than a 2311+2327. :)

Could I use the 3115 with the 3114a for the 2311/2440 just on the hf. Tie them Toghter on the Input terminal.
