Aquired vienna acoustics beethoven. I believe these are older series. Not vienna beethoven grand or baby beethoven.
2 mid range drivers, 2 bass drivers.
I also have vienna maestro center channel.
So center channel drivers loom identical to vienna beethoven midranges. Same 7ohm resistance (probably my ohmeter gives these odd values. but basically identical resistance )
Maestro center channels drivers are magnetically shielded. Beethovens are not..
What are the chances that these drivers are completely different .. I mean they look identical. Just a magnetic shield on center channel drivers.
Will try to reach vienna (speaker company no the city in europe) on Monday. Part numbers appear different.
Reason for this inquiry is that 2 beethoven midranges are damages. Foam is torn a little. Would like to Swap clean maestro drivers into beethoven

Looks like vienna uses seas drivers..just did quick forum search. But not sure which ones are in beethoven and which one in maestro

Have a look at the drivers - the polycone is ribbed and the baket is like no other I have seen. I do not believe Seas would mold custom baskets, but who knows. The surround is inverted as well.
The Fl-tec 4 midwoofers they use are custom made for them in China, I know this for sure, but no idea about the other drivers.

Those look more like baas drivers with radial reinforcement "ribs" or spokes.
This is the driver on maestro which looks identical to beethoven midrange.

i narrowed woofers to 3 seas drivers.MP14RCY, MT14RCY, MP14RC/TV attached are specs.
i believe i have mp14rcy in beethoven
and mp14rctv in maestro center channel.
need to weigh on the scale the speakers to definitelly zoom in on 2)
they look very similar specs wise. these are the most expensive i've ever had. all 8 ohm. MT14rcy looks most different. operating power is 8 watts as opposed to 4. and frequency response differs from MP drivers.
would there be any problem interchanging these drivers? improvement, downgrade in sound.. if these were 200$ speakers i'd swap things out without thinking

All 5" polycones with dustcaps as far as I can see. Troels uses a similar driver here:
T14RCY-P
SEAS drivers are incredibly interchangeable. Mostly 8 ohms, and they've been using keeping chassis size consistent for years but are on the 15 series now, rather than the 14. Also mostly 1" tweeters in on 104mm chassis. So the old 25TFFC is actually almost the same as a newer 27TFFC.
It would make sense to use magnetic shielding on a centre, but who has cathode ray tubes any more? 😀
I would think you can find a refoam/rubber surround kit easily enough. These are nice old drivers. I mentioned you can buy tweeter ferrofluid from parts express. It dries out after 20 years. Those tweeters look easy enough to disassemble. Possibly SEAS Excel.

Hi Richard_James,
It's very difficult to identify a driver without knowing its exact model number. Besides the official drivers, Seas produces a large number of undocumented OEM drivers for loudspeaker companies in the whole world. Even when drivers look the same, they may be different internally. And they are hardly available.
From your picture I would say it's actually a transparent polypropylene cone. AFAIK the MP14RCY is black and not transparent.
Attached are 3 Seas drivers with transparent cone. They have been very popular for a while in the German diy market, but they are OEM as well. They have been sold under a German name, not the official Seas model number. The P14RC-H is specified as woofer, the other two as midrange drivers.

Thank you everyone. . Viennas bluebird distributor seems unresponsive with replacement drivers. I think I can live with 3mm tear In rubber. Glued that tear with speaker refoam kit glue from the back side. Invisible. Also midranges and woofers on these speakers move so little.. almost staying in one place. I did few refoams of paper cone speakers. It was easy. A little hair dryer on dust cap was needed. With newer glues and rubber I am afraid to make things worse
. I tried to disassemble one burned kevlar woofer in bw speaker. Just out of curiosity before tossing it
Rubber is not meant to be serviseable. Superglued to kevlar. Same thing with dust caps.
Might swap drivers around to see if there will be difference in sound. But these beethovens sound so good. I am afraid to change the sound. They actually produce audible bass lower than many subwoofers I've had. Probably will limit service to ferrofluid in tweeters.

One thing I noticed.. when u push the midrange driver on beethoven it kind of springs back slower than on maestro center channel. On maestro it springs right back. I noticed this on various speakers in the past. Some woofers spring right back in place. Some do it slower. Whats causes this ?
Edit: beethoven midrange section seems to be a closed sealed compartment. But I am not 100% sure. It's very weird
When u press on one midrange the other midrange kindnof pops out . Logical. When u press on one woofer u would expect the other woofer to pop out due to pressure increase inside the box. But instead it kind of pops back into the case. Follows the direction of the woofer u are pressing on with your hand

Just to add for future Google searchers. Vienna uses scan speak tweeters. D2905/930004 on both Original beethoven (code 09446 pw 370)and maestro center (code 10550 pw:450) channel. Maestro has 2 magnets (shielded) beethoven tweeter comes with one magnet.
Not cheap.. 160-180$ each..
