Default Royd A7 repair

I have got a pair of Royd A7 which I purchased in 1990, and now came back to me after I gave it to a friend some ten years ago. Unfortunately one bass/mid unit seems to have been fried. Not a single tone from the chassis. Resistance measured at the removed unit is >1 MOhm.

I really want to save these speakers as I really love their sound

I know that there are no genuine spares available for the bass unit, so I`ve been looking for alternatives. Data I have collected from an old royd product flyer is: 8Ohms, peak power 60W, 89dB(1W/1m), bass resonance 60Hz; Also important would be the magnet dia, as this goes into the bass tube in the cabinet.

I have found several speakers that would fit physically, but I don`t know what spec is the most important to match - resonance frequ ? effective area ?) What do you think about this one: Visaton - Lautsprecher und Zubehör, Loudspeakers and Accessories

or this one: www.wavecor.com/WF138WA02-04_specifications.pdf has got exacly the same resonance frequ. and sensitivity, but the magnet wont fit without modifications

Any thoughts highly appreciated

I now tried the Visaton driver, and it sounds very different. Not much bass- wise, but it has som (harsh) treble. The speakers doesn`t have a crossover for the bass driver. The original driver does not deliver any treble though...
