I had an EKO Ranger 6 many years ago, but beside the weight (although probably also due to it) I found that I could never get much volume of sound out of it. That great big block of wood where the neck bolts on (just like a solid electric guitar) seemed to take away a lot of the resonance. Isn't the front table plywood - it definitely had a very hard varnish on it. I found it an easy box to play, but unamplified it just wasn't up to acompanying my (not very quiet) voice in pubs etc.
