Default mid-woofer replace suggestion for MS Konsens II

Hello
please if you can help me I have built the following kit MS Konsens II by Intertechnik
ftp://radiozona.myftp.org/Radiotehni...nsens%20II.htm
MS KONSENS II Gehuse
MS KONSENS II Frequenzgang
MS KONSENS II Weiche
my daughter broke down the mid-woofer SEAS Wt 171 and will have to replace the speaker that is no longer manufactured contacted the intertechnik and the Seas for what speaker they suggest but no answer. I do not know many of these things I just like the construction.
if you kindly suggest me some speaker preferably with the same diameter as not to spoil the box regardless of the brand that fits the characteristics of my speakers
if necessary I replace both and the good from the other speaker.
Thank you very much for your time
Pavlos

REPAIR/RECONE: Before we go for a replacement check for a repair of that driver (or pair) or recone with a professional repair shop. You have the second item (pair) what is useful for any detailed measurement needed (before/after).

REPLACEMENT: First would be important to identify this driver to match it with it's complete specs (electro-acoustic parameters).
Also at this time check (post in forum) for the size, internal/external diameter, or if matches the size of a standard reference driver.

Now, for some links. Identify your driver first to match correct spec-sheet or most similar. Here some vintage list of SEAS drivers.
SEAS VINTAGE PRESTIGE WOOFERS

Is your driver in anyway similar to this one? What is the reference number for it (H####)?
SEAS H0630 CC17RC (17 cm woofer) we can read this reference in the bottom: W17-101. Is it a paper cone?! After identifying the driver is less difficult to go for a similar/equivalent.
Another interesting link on similar driver. Seas WT 171 H634 (XP)
After all, without the proper driver, it's a very difficult job and time consuming, almost impossible for a newbie, not running some simulations and reverse engineering of a complete speaker system.

Grateful for your concern and nice postings of your document set but what we need is the full driver specs.
Something like the specs linked below.
You should know that the material of the cone is a "PP/TPX based cone" (look here) that you find in some of the old and new Seas drivers but the physical exterior dimensions are now "18" in the modern drivers and not "17" (170.4mm).

The Seas vintage drives might not be commercialized anymore but you can try always contacting the source at SEAS.
I made a list of the vintage Seas drivers that would be valid equivalent drivers both in T/S specs and physical dimensions. Notice that they are discontinued. Using a different driver requires a new crossover/testing/simulation of a new speaker and components+drivers. Some newbies don't understand that, they are the "dummies"...
Now to start the list the most close in spec driver that I found follow next by the other similar references to your driver.
Seas H0627 P17RC/TV
H0352 P17RCY
H0548 P17RCY/P
H0571 CB17RCY/P

Note: If you know of someone speaking Russian try this link. Always run payments with controlled bank accounts (bank transfer operation), don't give away your credit card number.
Post results. Have fun.
