On paper a full range SET amp is not a good technical match for optimal performance with most any (inefficient) smaller speaker with extended bass. Probably one of the biggest mismatches possible in general.
But that does not mean it might not sound good still at least in some cases. It will work and distortion not be an obvious issue perhaps up to a certain volume level but that’s about it. A lot always depends on the needs of the listener.
Adding powered subwoofers with crossover directing the low bass solely to those would solve the problem and would likely allow the SET to do its thing best and sound fantastic if done right.
