* Extended Position <br />Recommended for larger audiences, the extended position allows users to elevate the L1 Compact loudspeaker array,

enabling it to project sound clearly and evenly throughout larger venues. Included with the L1 Compact system are two interlocking L1 Compact

extensions used to elevate the array.

* Collapsed Position<br /> Recommended for smaller audiences, the collapsed position allows the L1 Compact loudspeaker array to be inserted in the front of the power stand, creating a very small profile. When used in this position, the system should be placed on top of a table or elevated stage. This will allow sound to project clearly and evenly throughout the room.

For optimal performance we reccommend using both extensions when the system is set up in its Extended position.

=== Drivers ===

==== Array Section ====

There are six high power drivers in the array section.

===== Vertical Dispersion =====

Any idea what the vertical dispersion angle is on the high end? [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/745104421?r=895106811#895106811 Bose Guy in Calgary]

Plus or minus 20 degrees. No tilting needed.

The vertical dispersion is only +-20 degrees which is pretty confined compared to most stand mounted speakers.

The curvature in the array is to achieve the +-20 degree vertical pattern. We designed for that pattern so the speaker would work in a typical raked seating area -- something we thought the L1 Compact system would be used for a lot, and we wanted to make sure that those seated in the front row of a cramped venue with the product in it's extended position would still get sound.

===== Convex arrangement of 6 speaker array =====

:I'm curious about the slight 'convex' arrangement of the 6-speaker array. Why that rather than a straight or even a slightly 'concave' arrangement? [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/745104421?r=759100021#759100021 Source: Dan Cornett]

The vertical convexity of the HF array will actually produce a very useful vertical dispersion at HF. The unit needs this. IF it were a straight array, you'd be shooting over the heads of, say, people seated in front of a bandstand looking up. That geometry coupled with the driver articulation (like the L1/II) makes for a spectacular distribution of sound, especially in the HF. It's amazing when you hear it.

==== Power Stand ====

The L1 Compact systems power stand has integrated bass with an 8" woofer and will play down to 65hz. The drivers in the loudspeaker array are indeed smaller than those used in the L1 model I and model II systems.

=== Voicing / {{T1 nl}} ===

We voiced all the L1 systems the same, so that tone would be the same on each.

Also, that makes it possible for the T1 audio engine to travel from say a Model II to an L1 Compact system with no additional change of settings on the T1.

=== Comparisons to Other Members of the L1® Family ===

These are anecdotes from people-at-Bose.

==== Ken-at-Bose ====

What I would say is that the L1 Compact system does not play as loud, nor as deep in bass, nor does it project as far into a room as either the L1 Model I or Model II.

It doesn't really offer expandable bass.

We think its performance and price are very appealing to a large number of people for whom the performance and price of the Model I or Model II are unnecessarily high.

If I played in bigger, noisier rooms, used bass and drums, or played hard driving rock/blues/metal, or had an instrument that really shined because of deep bass etc. I should be steered to the Model I or Model II.

For a quiet, attentive audience I would think that a singer songwriter could comfortably entertain 150 people, give or take, with an L1 Compact system

If the room or people are noisy, take that down to 50.
