I am currently using a couple of Bose L1 model II systems with the new B2 subs.  I play in a 4 piece band and for most situations this setup performs quite well.  I do find however that in some venues there just doesn't seem to be enough power.  The system has built in protection, so if you push it too hard it does some whacky things.  I love the fact that I can set these up behind the band meaning I don't need monitors, and you can't beat them for lightweight portability but I'm feeling the need to get something that will perform at any venue I have to play.

I will maybe see about getting my hands on some of this gear for a weekend to check it out but in the meantime I'd like to try to get some info here.

1) On the L3t, there is a mixer section on one side, presumably to be used if you are using it as part of a PA, and the line in section on another side.  So my question is, are they completely indpendent of one another.  There is feedback suppression on the mixer side, can that be engaged if you are plugging into the PA input side?  I know that the M20d has the same feedback suppression but if I am using a different mixer can I take advantage of the feedback suppression built into the speaker.

2) Again on the L3t, how is the bass response if you aren't using subs?  I imagine that without the subs connected it's going to be full range, but I am just wondering if anyone has just used a couple of L3ts as front of house for a band and how did it work out.

3) Whether I am able to use the feedback suppression on the speaker or if I end up getting the M20d "again" (had one for a day until I tried to use it for recording and found that it has a 1/2 second of latency), I'm wondering if anyone has tried using this system behind the band kind of like I am currently using the Bose systems.   We only really have 3 vocal mics, guitars, bass and electronic drums are all direct.  If there is no way it could work, and providing question number 2 has a favourable answer, I am thinking I could start out with a couple of L3ts and a couple of L2ts for monitors.

It's always a money losing proposition when you have to move from one system to another, so you can understand my apprehension and need to try to learn from others experience before I make a big decision like this.  I could see myself trying to get into some subs at some point but I think I would have to wait until Line 6 comes out with a scaled down sub maybe with a couple of 10s or a single 12" driver.  I've seen the L3s in person and it's just to much of a monster for me to consider carrying around.  I figure since they came out with the L2T and L2M it's a possibility.  I fit all my current gear including lighting into my Mazda 3 sport.
