Default Does it worth to invest on cones for a Tannoy 605 II?

Hello,
I recently got for free a pair of Tannoy 605 II speakers, they have the midbass cones broken so I took them out and though about getting a new pair of good quality cones. They seem to be well built, sturdy construction.

I have had a look at Seas CA18RLY, that costs around 70 each one. So that makes a total of 140. Other speaker models does not fit well because their deep (78mm) is a tad bit more than the available clearance inside the enclosure (75mm).

Is that the best way to waste some money, or does it really worth to put a little of money into it to have a good set of shelf speakers?

Seas CA18RLY are good speakers, but you need to be sure the box size and tuning is suitable - what are the internal dimesions, and what is the port length and diameter?

Alternatively, you can have the Tannoy drivers re-coned

It is a box sized 20cm depth, 30cm tall and 24cm wide. It has a port of 5cm diameter and 12cm lenght.

Thanks!

Buy another pair of Used Bookshelf Speakers.. complete ??
Maybe even another pair of tinyTannoys, IF you prefer their sound.
Lots to choose from, as Used Speakers sell for very little.
Less so than rebuilding ruined ones.

at 14L, the box is too small for CA18RLY,
ER18RNX would be suitable if you don't want much below 50Hz, and can deal with implementing an appropriate crossover...

ER18RNX doesn't fit in mi enclosure. How can you discern one could be appropiate but the other needs a bigger enclosure?

BTW, another two options I am thinking about (that fit properly) are Scan-speak 18W/8434G00 and 18W/8424G00.

Any chances to that?

Thank you, best regards

On a mission? Those Teeny Tannoys are in boxes made of poor quality materials.
They Could Not conceivably be made cheaper.
IMO Not worth saving from the dumpster let alone fitting fresh drivers ($$) to.
That WAS your initial question.. was it not ?
IF you must... at least build fresh boxes of actual wood?
