I can assure you that any of the models in the π Speaker line work well, and I've connected many of them to my Paramours. Even speakers that require a high degree of amplifier/motor damping sound great. There's plenty of bass with control, the midrange is pure and the treble is crisp.

Personally, I would suggest the Professional seven π, Professional four π, Theater six π and Theater three π speakers as personal favorites. The Theater four π / Paramour combination sounds excellent, and is probably one of the most popular Bottlehead system configurations, certainly here. And the Tower two π speakers are also really great, especially for their cost. That gives you quite a range of prices, so there is a nice system for every budget.
