It look like to me that the Audya is a little picky about PA systems.
We are using ours with A Roland KC550 and I am no impress. Best sound output has been with a Event SP8.
What you guys use or recommend?

I think DonM use Bose Compacts.

no offense, but how about a full range PA
to get a full range sound ???

like bass bottoms with tops, of a great brand like QSC, Yorkville, JBL, EV, , EAW, RCF, and the likes

nothing will sound GREAT through a simple, "small" keyboard amp

1 speaker in mono can only do so much

to add,

that Roland is great as a monitor,
NOT as a full PA...

just my $0.02

I do use two Bose compacts. I have also used it with the big Bose L1, a Logitech Z2200, two Barbettas, and several other powered speakers.
It sounds good through all of them that have good, full range, but to me the Bose sound best. Of course they should, they are pretty expensive.

I have played for a couple of years now with Dynacord D-lite 2000 and with an extra bas. I think this is a vey good system for us whit two singers and one Audya
