We have been using two Bose Compacts with our Tyros 4. Works nice in smaller environments.
We have been getting some larger gigs again and I've had concerns that the Bose compacts won't cut it...especially at the low end of the spectrum.
The local music store carries Yamaha...same store where we bought the Tyros 4. So I purchased a DXR15 powered speaker to use at the next gig.
I've been pleasantly surprised with the sound of the DXR15. The low end had been missing on the compacts in our larger venues.
I had thought of getting a Bose L1 Model II system with a B2 bass but honestly don't want to pay 3 times the cost of the DXR15...at least at this point.
I also thought of just buying a Bose B2 sub to use with the Bose compacts we have until I found out that the DXR15 has a mixer system that allows for use as the only speaker at a gig.
Like I said, we'll see how it goes.
