I haven't had the chance to hear many of those models from Prestige series. I have heard some of their lower end and some of their studio monitors. The (dual) concentric driver tech is an interesting one though. I personally am not too keen on singular driver configurations. It's an interesting comparison between their modern tech and our classic 3 way design. The biggest glaring difference, while there are many, is our midrange. The reason we chose to utilize dome midranges for the three way design is because of the resolution and imaging yield. I think it is widely excepted that a well executed dome midrange can offer an extremely satisfying playback experience(maybe more so than cones? - anyone?). That said they can be a bit difficult to manufacture, and must be held to a very critical spec, as distorion can creep in along the way. Our crossover design with OB1i, PB1i, and EB1i is x'ed at 380 & 3.8k @ -24db/oct. So it is a pretty steep curve that allows the drive units to operate more uniformly efficient - combined with the ATL we push their performance level especially with the LF a bit higher. Any circle members who are familiar with the Piston-Nomex driver know that this driver just oozes muscle just by looking at it.
These Tannoy appear to be very sensitive, which would explain their moderate power rating (Prestige is at 97-99 db 1w @ 1m is pretty high, the EB1i is @ 89db)... The EB1i comparatively can reach a good bit deeper in the lower frequency register - down to 19hz. I would say that you could safely power the EB1i with about 500watts (14B or 7B's anyone?)... Although a good a good bit of fun was had with Mac 1.2kwatt in the red aa.
So between the two differences appear to be vast, so surely they will offer entirely different sounds... It just depends on the sound that you are after.
Also, I thought our i-series was pretty British looking, the Prestige series takes the Anglo-Monitor-aesthetic to a whole new level
