Two versions of Fane's Full Range Model "Studio 5M" - 100 db and 92,5 db ??

According the datasheets there are two versions of this midrange model, also suited for full range applications without tweeter:

1) The vintage version, that I know und that I have heard several times (100 db version)

Very similar was Monacor's "C5-50M" from Mc Kenzie order code 45.0340 from Monacor's Gerrman catalogue K39.

2) the currently available version "Studio 5M" with only 92,5db sound pressure level but with the same outline (at least according the images by Fane International) go to the new data sheet about

Perhaps the 92,5 db by the new data sheet is a misprint. Or is it a completly new design with the old model number?

However, the Studio 5MN (neodym magnet version) about
http://www.fane-acoustics.com/downlo..._5MN_Specs.pdf
is more close to the old "5M" version than to the new "5M" version.

Who can post exact informations in this case ?
Thank you very much for your efforts.

BTW - I need this informations for replace the transducers in an old near field monitor from d&b, model "E1" - images by post #2 about

Don't worry, the efficiencies are almost identical for the 3 models : 1.6%, 1.65%, 1.7%.

The different numbers 92.5 dB vs 100 dB are just honest for the first one and marketing department for the second. They claim that the efficiency is the level of the nasty peak at 5000, common practice. Once equalized to be flat, indeed, only 92 dB will remain in the best case.

These measurements might be helpful as well.

thank you for this pdf measurements.
But the speakers are the models "Studio 5FR" and its successor with kevlar diaphragm, the model "Studio 5FRK".
I ask to the model "Studio 5M".

Which bottom I must use about

Edith sagt, der Downloadbutton hat auch etwas zu bieten.

Btw, an efficiency of 1.7% is 94.3 dB and 1.65% = 94.2 dB.

Thank you also for this dataof the 5FR. I have seen the VAS been quoted as 24L and 2.4. from different spec sheets I don't know which one is the missprint. However your Result of 16.54L trends towards the 24l?. Fs quoted as 43Hz you found it to be fs=52.9Hz and I found my 5FR speakers to be fs=69.9 to 71.3Hz.

I think little speakers can vary alot, so the only way to really know when designing the box is to do the test of theile & small yourself, as you have done.

To find Vas=1.15*[(fct/fs)^2-1]*Vb

Vb=Test box Volume [suggest 5lt for this model(20cm*20cm*12.5cm)]
Fs=Free air resonace
