L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

I have 3 L1 Model 1 systems, each with a B1.  I run three musicians (bass/vocal; guitar/vocal; keys/vocal), each to his own system.  The drums are routed to all 3 systems.  Here is the problem:  one of the units crashed.  Bose says they cannot repair and have offered to replace it, either with a Model 1S or with a Model II.  My question:  which of those choices will best match up with the remaining 2 older systems?  Any suggestions?  Also, how practical is it to try to find a 3rd party who will repair the old unit?  I love those old units!

Original Post

I ran into the same situation where my L1 M1 started exhibiting issues. I got a L1 M2 replacement from Bose for it and reused my B1. It was my understanding that some of the critical electronic components used in the M1 were no longer available so it wasn’t possible to fix it.

IMHO the M2 would be the best match to your other M1 systems. The 1S only has speakers in half the column, so you would get less projection in comparison to the M2. In small venues you may not notice, but in larger venues you would. 

Just some further observations in switching to the M2:

I found that the M2 bass wasn’t as robust with a single B1 so I got an additional B1 on the used market to keep expenses down. From what I was told, Bose redesigned the speaker array and relies more on the subwoofer and took some of the bass frequencies out of the M2/1S speaker tower. 

You’ll find the M2 tower has an articulated speaker array that disperses the sound much more evenly than the M1. So you might find the M2 doesn’t seem quite as loud as the M1 when standing directly in front of them. However, the M1 will not be as loud as the M2 when you move off axis from the tower. It just takes a little getting used to. In the final analysis, the M2 is as loud but projects it’s sound much better overall.

You’ll find passionate opinions on this forum as to whether you should go to a B2 instead of using the older B1s. For us, the 2 B1s worked fine. 

Finally, you may already know that either the M2 or 1S do not have a multi channel mixer in the base unit. That all got taken out. This means you will have to get a separate mixer if you wish to connect a mic and instrument into a single M2/1S. The upside is the new base is sooo much smaller and lighter to handle than the massive M1 base. There are numerous inexpensive mixers out there that you could use including Bose’s own T1/T4/T8 digital mixers. For our acoustic trio (2 vocal, 2 acoustic guitars, 1 upright bass), we use a Behringer 1202FX into a single M2. 

Hope this helps.
