If the speaker choice is still open, consider some speakers that are more efficient (that is if you are planning to keep the amplifier).
I would be on the lookout for something in the 93-96db efficiency range; generally speaking its not a good idea to push a single-ended amplifier very hard (and FWIW, this amp poses no threat to the proposed speakers).
