It’s always an issue with portable setups, trying to get good sound quality. Previously we’ve recommended the Edirol/Roland/Cakewalk MA-7A speakers. The problem with these is the additional weight that tends to cancel out the benefits to the highly portable Ensemble system.
During a recent visit to the Music Therapy department at the Royal Hospital for Neuro-disability in Putney, London, I was introduced to the Logitech range of laptop speakers. It’s a highly portable speaker, powered from USB, that clips onto the laptop screen. I’ve got to admit I was sceptical, but quickly won over by the volume and quality of sound produced.
I’ve now purchased a Logitech Z305 (about £35 from Amazon) for use in demos. Highly recommended.
