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.

Hi jdycus@ec.rr.com,

Thanks for your question.

How close can one stand in front of an L1 Compact without affecting sound to the audience?

It would be difficult for a person to block the low frequencies coming from the power stand.  The low frequencies will likely diffract around a person-shaped obstacle.

Please click the picture to see it in context.


The sound coming from the L1 Compact Speaker Array at the top are higher frequencies (above 400 Hz) and more likely to be obstructed if a person is blocking all the drivers between the speaker array and a listener. However, if the listener can see the speaker array behind a person standing near it, the listener can probably hear the array.

You can see in the picture to the right, the drivers in the speaker array are articulated left and right and up and down. This gives you nearly 180 degrees of horizontal projection and 40 degrees vertical.  

It's unlikely that even a very tall person could stand close enough to block the speaker array enough to affect the sound in the audience.  The sound will diffract around the person, or reflect off walls.

Are you having problem with the sound being blocked?

Thank you for reply. Tomorrow will be the 2nd time I have used it with my quartet. The first time, I placed it adjacent to the left most singer in the line because we were placed up against a wall. This time I will have room to put it a few feet behind singers, but because of schedule will not have time to experiment with placement. Wasn't sure to give it a try behind.

Hi Guys, I stand 6' 2" so yes, I can block some of the top array HF signal, although for a solo singer like me it's not an issue

The Bose Compact measures...

about 5' 2" from floor to bottom of HF Array

about 5' 9" from floor to middle of HF Array

about 6' 5" from floor to top of HF Array

Depending on the height of your singers there could definatly be some interference / blocking of HF signal. With 4 singers positioned directly in front of the system it could be even more significant.

My suggestion (I do this all the time) is to place the compact on a 12" high riser (I use one of my small gig equipment boxes) to get up over your singers and out to the audence. This method also seems to throw better into the room and help reduce feedback issues as the mic is a bit more below the HF array.

Just my thoughts on this...
