Help Need Focal 5N411L woofers and specs 5N411

The "l" in 5N411L means "longer voice coil". The Bl & efficiency went down, the Qts goes up a tad, and the Xmax increases, as well as the moving mass. Fs may drop a bit as I remember.

Hi Vox

Where did you find that pair of 5N411L. I have tree of the 5N411l from a pair JM Lab Profil 5. I got them for free because one of the four speakers didn’t work, and now i am looking for a single 5N411L?

In my opinion, 5n411 L, means "magnetic shielded"

Hi,

i phoned focal last month since i was looking for the same information. Here is what they gave me (i would have expected more but the guy was in a hurry) :

5N411 :
-----
Fs : 46.52
Vas : 17.36
Qts : 0.296
Qes : 0.34
Qms : 2.27
Sd : 86.59
Re : 6.7
Mms : 7.1
SPL : 88.95

That's all i have. If you manage to get the frequency response of the drive, i would be very interested in having it.

Regards,

Marc.

Hey VOX,
I have a Driver spec./Technical data cataloge from Focal that has the 5N411L Bass-Midrange in it. I think I may have another piece of lit. at home somewhere with the 5N411?

If you want the specs for the 5N411L I'll email you everything that's on the page or try to scan it and email it. I'll look tonight for the other info regarding the 5N411.

You could try Elliot at Zalytron.com with the question as to what the "L" means or Kimon Belles at Orca.com - I haven't dealt with him in a while but he was always kind with info and responses.

I assume you've contacted partsexpress, madisound, etc. If you haven't also give snippets.org/ldsg a go. All you need to find, after all, is s/one with an old Focal catalogue...

The new series are 4211/4311 midrange/woofs with an Fs ~50-60Hz. -- but as you said: specs comparison???
Good luck!
