One of the all-time great sounding systems...
I have used the Bose T1 ToneMatch mixer with the Bose L1 (Model 1S with the B1 Bass Module) regularly starting around two years ago for an on-stage monitor mix for clubs that have over 50 people (with Bose 802's for FOH), For shows in smaller venues that hold less than 50 people, I sometimes use just the L1 to cover the audience with my vocals and keyboards. The sound is spectacular. I wish Bose would rate the wattage so I can compare it to my other systems, but I can say it is not as loud as 450 watt into 4 ohms out of each channel of my stereo powered Mackie 808S mixer.
Great sound, Lightweight
Sounds great for small shows (<300). I use 2x B1 Bass speakers for more robust lows. The Tone Match Audio Engine is great for small setups. I bypass it if I'm using a larger mixer, such as my Behringer X32. I just send a stereo XLR out to the 1/4" input and I'm good.
