Tannoy 3849 speaker replacement for FSM monitor's

Hi I am looking for a recommendation for a speaker replacement for my Tannoy FSM monitor's. I took one of the 15" woofers in to get reconed and the repair shop disappeared, along with my speaker... Anyway I am in the need of a suitable replacement, I tried contacting Tannoy but no response.
looking at partsexpress I though this one might be good
