I own a pair of Odeon Rigoletto speakers. The Rigoletto comes standard with modded FE164 drivers.... the mod is basically just the removal of the whizzers. I have also "Mod-Podged" the cones and added phase plugs fashioned out of small vacuum tubes. This might be too general of a question (without more info), but I am wondering if replacing the FE164 with the new FE166en would bring anything positive to the table. Does someone have any thoughts on the subject? Thanks for your help!
What range do the FE164 cover?
They are much closer relation to FE167 than FE166... 166 is more efficient and needs different box loading.

Hi robber222,
I have those same speakers! Speaking strictly as a newb, the biggest improvement was just disabling the tweeter and taking out the crossover, which it sounds like you've already done.
If you want to roll drivers, just be aware that the chamber volume needs to be carefully matched, and you'll be in "trial and error" territory unless you simulate the enclosure.

I have a old fe164 pair with the suspensions fatigued.I think the Qts is now low.
¿Can I replace for a FE166En?
¿Are they similars?
The cabinet is a TQWT.
¿May be re-align only change the stuffing?
Cheers

What Dave said. The FE164 was the direct predecessor of the FE167E which was the direct predecessor, well sort of, of the FF165WK. the FExx6 series is different.

but ...
"FF-WK series are fullrange speaker units ideally and exclusively designed for a bass-reflex enclosure". Will works well on a TL, Horn or TQWT cabinet?
The Qes, Qms, Qts params are very similar as the old FE164 . Good.
Xmax 1.85mm more overhang as FE164.(1mm)
Re 6.5 Ohm (7.2 Ohm FE164)

If the cabinet is well designed… i am just now prepping FF165 for Frugel-Horn XL.

Well, I will try the FF165wk. The cabinets are a 20 years old Voigt-pipes.They work fine with FE164.May be It will need only some changes with the stuffing.
Bob and Dave... Thank´s

Before a only a hour I have tried a FF165wk at the place of the venerable FE164 into my old TQWT.Is incredible.
It work fine, very similar...and without break-in.
At the moment any modification , like add or take-off stuffing,.. Notthing."Plug&play" !!!
Thank´s Dave and Bob for your recomendation.

The drivers (FF165wk) are worked now about 30 hours.
Sounds well, but the sensibility i think is coming back.Rare behavior.
Is possible?
The sensibility is defined by the cone mass and the magnetic flux.The stuffing into the cabinet also, but ... i have no changes.
May be the reason is me: The influenza (gripe) don't allowed to my ears work well.Sure.

sensitivity change with driver use
The qts and fs drop slightly with use as the moving parts soften. They don't change enough to increase efficiency noticably.
E.g I got one driver from a set of four that is "broken", the magnet is undercharged. Qes is high, so Qts is 0.6 whereas the others are Qts 0.37 ...but the weak one is only 2.4 dB less efficient. The frequency response of the broken one is very similar too, with the good ones giving just a trifle more high frequency extension, and slightly flatter 1-2kHz
Break in of a driver has much less effect on the qts than this difference between a defective driver and a good driver. Efficiency change is barely measurable.

Thank's . I noticed a less sensibility in my ears... in all: listen teh radio, in the street,..
The tow drivers are similar level.
I will wait for better moments.

The drivers are now about 100 h break.in.They work very fine.The not real sensibility problem was only me.The drivers work ever well.
May be the reason is the big time between the drivers production and live, but the FF165wk type at this moment is better ever as the venerable FE164 one.
Well stuff.Is the best FR 6.5 inch. than I tried... and cheap!!!
I'm very glad.
Dave and Bob...Thank's again.
