A friend of mine has one of those ultra-small, ultra-light bass amps - I think Bugera or Behringer, which is like 1500 watts. There are lots of choices for tiny, powerful heads. He plays through a combination of Bugera Turbosound 2-10s and a 1-15 - mix and match. Sounds great and weighs hardly anything. The Turbosound neo speakers are great and on the less expensive side.
