I am a Vincent dealer and the amplifier is remarkably capable.
So the pertinent questions become:
1: Room Size is the room is bigger than 12 * 12 or so get a floorstanding speaker
2: How loud do you play? If you want to play loud and the room is large then a more efficient speaker will be better.
3: Taste in music? If you play big anything or loud rock and roll you will need some bass and dyanmics.
4: Price the more you have to work with will determine the resolution you can accheive.
