I own a Bose L1 w/2B1 Bass Bins and I love the sound.
Your application seems to be perfect for the Bose system it is a all in one system
Amp, Speakers etc.
You can use your own mixer or use the new T1 Bose Mixer with the L1. The T1 can be connected to your laptop via USB and you eliminate the need for a sound card. It has excellent effects for vocals and music. I use the T1 and have found it to be far superior to any mixer I have used (Yamaha or Mackie)
The price tag for the L1,B1,T1 combo is like $2800 and seems a bit pricey but you will fall in love with the unit. Now that I have experienced Bose I could never go back to a conventional PA system.
They have a musicians forum that provides excellent support from Bose users and engineers from all over the world. It's an amazing community of folks there to help you.
Thumbs up on this end
