I seem to remember a few comments about the MJ Acoustics Pro50 subwoofer a while back. I did a SEARCH of all forums (subject only), couldn't find it.

If you are using this, could you tell me your impressions? Could it be used (along with just the internal speakers in your keyboard) for small/medium gigs, or is it too small/not enough power? I know this is an "opinion" thing, but I am looking for opinions/comments from those that have used it.

Also, is it REALLY less then 9kg, i.e. VERY light weight?!

Thanks for any comments!
