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.

Yes, I have an MXR M81 – is that as good as anything?

In this scenario my bass goes through the M81 to the A1 to the B2, right? Are you aware of any bassists who use this as a primary standalone setup as opposed to something like an Acoustic Image TEN2?

Edit: Removed some personal information that appears to have been included unintentionally.

Hi jazzbikerguy,

I just looked up the MXR M81. I can't predict how well this would work.  Do you have a Model II and B1 or B2? If so, you can get an idea of how this would sound.

  1. Set up the Model II Power Stand  without the Cylindrical Radiator (tower). It's okay to run it like that.
  2. Connect your bass to the MXR M81.
  3. Connect the MXR M81 to the Model II Power Stand  Analog Input.
  4. Set the Model II Power Stand  Analog Input trim to about 10:00 o'clock
  5. Connect to the Model II Power Stand  to a B1 or B2

How does that sound?


Hi jazzbikerguy,

Can I drive the B2 with something other (smaller) than the L1 series 2 power stand?  I'd use it for upright bass.

Pardon the question, but why would you want to do that? Are you trying to save on weight? If so, then OK, but I would have thought that you'll be losing a few frequencies by using a B2.

The frequencies of a Double Bass being: E1 at 41 Hz to B3 at 247 Hz with Harmonics up to 7 kHz.

As the B2 has a frequency response 

  • Frequency Response: (-3dB) 40 Hz – 200 Hz
  • Frequency Range: (-10dB) 35 Hz – 220 Hz 

 (Taken from the Wiki)

aren't you going to be losing an awful lot of Upright Bass typical sound?

I can understand you wanting to make use of something that you may already own, and also that the reason for your question may be to save having to transport equipment, but do you want to compromise on sound?

If you're wanting to have a downsized rig and are prepared to or can afford to buy a good sounding Combo then you may find something interesting in the Mark Bass product range (maybe even the Gallien-Krueger MB115-II which I've just seen for 449$ US at Sweetwater).

Advantages: Small, lighter than a B2 or Complete Model II set up; everything you need is included (you don't need a pramp or a Packlite (which you'd have to buy if you don't already own one roughly 360$ US,).


Disadvantages: You'd have to buy one (but if you don't already have a Packlite .... ); doesn't look halfway as cool as a Model II with a B2 set up. 

Just a thought, and I'd be really nterested to know what you actually decide on.




Seagullman -

Tanks for your response; I didn't do my research on this, and your specs talked me out of it.

I'm fortunate that price is not a factor - I'm just looking for my best option.  I'm currently fixated on the Genzler BA 10-2.  I was hoping to use my MXR M-81 with it, although I'd consider the matching Magellan 350 if anyone thinks there would be an advantage.

My only concern is that I may want to have the possibility of a second instrumentalist (guitar) to use the same amp at the same time - is this not possible/a bad idea?

Thanks for your help!

Hi jazzbikerguy,

thanks for the update.

To be able to do this well and have the guitar sounding like a guitar your system would have to have a wider frequency response than a normal bass amplifier as the guitar frequencies are higher. This would definitely limit your choices and could well put up the price considerably.

I've had a look at the Acoustic Image TEN2 that you mentioned and the specs seem to show that this would be able to do what you're looking for. This would however come at a price. I can't see where you're located from your profile so I've no idea what the prices are for equipment in your area. The Acoustic Image TEN2 does seem to have a pretty hefty price tag though. It may actually be cheaper and more flexible to have a small dedicated Bass Amp and a small dedicated guitar amp for the times where you may want to play with a guitarist (maybe something like ZT Amplifiers The Lunchbox for example?). Do you have to provide the guitar amp? These are just thoughts and suggestions for you to maybe consider. Another piece of gear which may be interesting for you could be the Acus One-10 if it's available near you. I don't know how well it will amplify your upright bass, but with the number of channels it has it's an extremely versatile acoustic all round solution. Less expensive than an Acoustic Image TEN2 and more versatile. You'd have to try it out though to see if it meets your bass requirements. It should cover everything else easily including microphones etc.

As I've said, these are only suggestions that you may not have thought of yourself and that may or may not be of interest to you. I'd be very interested to know what you eventually decide on.
