The Tannoys work well with the TS12 or alternatively the TS500 if you are looking for a more attractive enclosure. If you have a large room there are other subs available , you are not bound to the Tannoy range.
The speakers are clear and detailed and will work well with any good quality amp. We have installed a number of systems with the new range of Pioneer amplifiers - the SC-LX81 in particular is a superb match and would be my main recommendation at this stage.
