Bose L1 Portable Line Array Systems

By | January 8, 2015

PA systems tend to be bulky and heavy. They’re difficult to lug around and take up a large amount of storage space. Don’t you wish there was some kind of alternative? Well there is! Find comfort in the amazing Portable Line Array Systems in the Bose L1 series.

The L1 Series is a set of portable line arrays paired with a bass module. The line array component delivers clean audio in a 180-degree horizontal coverage range. This means that sound reaches even the far sides of the venue where the L1 is being used.

There are two models of line arrays with a multitude of package options. The two models are Model 1S and Model II. The main difference between the two models is in the line array itself. While the Model 1S has 12 speakers in its line array vertical enclosure (with a max volume/SPL of 112dB/118dB peak), the Model II has 24 speakers (with a max volume/SPL of 115dB/121dB peak). There’s also a bass line out on the power stand of the Model II that isn’t included in the Model 1S packages.

Here are all of the available packages for the Model 1S: Single B1 Bass, Double B1 Bass, Single B1 Bass with T1 Audio Engine, Double B1 Bass with T1 Audio Engine, Single B2 Bass and Single B2 Bass with T1 Audio Engine.

Here are all of the available packages for the Model II: Single B1 Bass, Double B1 Bass, Single B1 Bass with T1 Audio Engine, Double B1 Bass with T1 Audio Engine, Single B2 Bass, Single B2 Bass with T1 Audio Engine, Double B2 Bass with A1 PackLite and Double B2 Bass with A1 PackLite and T1 Audio Engine.

Those two paragraphs might seem overwhelming, but fear not! We’re here to help. The Single and Double refer to whether the package comes with one or two bass modules. The B1 and B2 refer to the type of bass module in the package. The major difference between the Bose B1 and B2 Bass Modules is in the drivers. The B1 has two 5.25” high output, high excursion drivers, while the B2 has two 10” high output, high excursion drivers. When either of the bass modules are plugged in to the L1 system’s power stand, the bass signal is automatically adjusted thanks to active equalization circuitry.

But what about this “T1 Audio Engine?” That’s an additional accessory that can be purchased separately, but there are also a few Bose L1 packages that include them. The T1 ToneMatch Audio Engine is a four channel mixer. It’s designed specifically to work with L1 portable line array systems. In addition to being a four channel mixer, the T1 ToneMatch Audio Engine has over one hundred instrument and microphone presets, a plethora of effects and dynamics processing types. These presets, effects and dynamics are all able to be globally assigned to every independent channel. On top of all that, the Bose T1 also features scenes, a chromatic tuner, a large backlit display, a rotary encoder, +48V phantom power and more!

What’s that you say? That doesn’t explain this “A1 PackLite?” Don’t fret, we’re getting to that. This is another accessory known as the Bose PackLite Power Amplifier Model A1. It’s a power amplifier designed for instruments that need additional headroom and an increased output in the deep bass range. Electric bass guitars and bass drums benefit most from this accessory, but it also improves high output playback of EDM (electronic dance music). This amplifier can power up to two additional B1 bass modules or one additional B2 bass module when used with the L1 Model II system. The A1 PackLite isn’t compatible with the Model 1S.
