the GW7 has no speakers. between the exr5 and the s500 is no contest imo..the s500 is far better except for one thing: on s500 choice is between drums only and full accompaniment, no in-between or muting trax.. on exr5 drums, drums/bass, combo, and full. if speakers were not an issue then the GW7 would compare favorably, as it also has that feature plus in other ways much better than exr5. ps..you are using a computer to send your query, right? you needn't be asking if gw7 has speakers..just google roland gw7 or any kb and your spec questions are answered.
