Tannoy monitors x-over

Which Tannoy model bookshelf speakers have ONLY 1st order crossovers? Having recently bought the Green Mountain Audio EOS HD I have been enjoying music more than ever, but im curious if it has to do with the 1st order crossover and time and phase coherence. So i've decided to try out some tannoys. The only one i can find in the Tannoy website so far is the Eyris DC1.
