This extends the official L1® System FAQ.
OFFICIAL FAQ item
What about using just the lower half of an L1 system's loudspeaker in places where the ceiling isn't tall enough for full assembly?
You can do it, but using only half of an L1 loudspeaker will significantly impact system performance. The EQ will be incorrect, and sound coverage decreased. Plus, in order to hear yourself properly, it's best to have your ears at the same height as some part of the loudspeaker—which may be difficult unless you're seated.
Additional Notes from MikeZ-at-Bose
Referring to situations where there is not enough height to install the upper section of the L1 Cylindrical Radiator® loudspeaker MikeZ said
- The easiest way to 'get through the gig' is to simply remove the top section and play through the bottom only. To balance out your sound in this mode, plug a cable into the 'bass line out' (don't connect it to anything).
- If course you lose a lot of performance from the system, but the show will go on.
Later in the same discussion Le5 Mark explained.
- by removing the top half the L1 speaker the impedance effectively doubles for this section thus reducing the power output of the mid-highs and the bass will be more pronounced. By inserting a cable into the "bass line out" the power stand will "believe" that a PackLite has been connected and it will reduce the bass output level and the sound will now be "balanced".
NOTE: The impedance issue affects the L1 Model I and L1 Model II. The L1 Classic uses separate amplifiers for the top and bottom sections of the L1 Cylindrical Radiator® loudspeaker. So the rationale for using a cable (or just a connector) into the bass line out may be different, it is still worth considering. You may also get decent results using the R1 Remote or T1 ToneMatch Audio Engine to turn down the bass output.
Follow up notes:
Question:Mike: Is it safe to assume that getting the 1/2 pole raised to approximately ear level will help?
Answer: Yes. Ideally, this is best. You need a sturdy flat surface to set the unit onto. A sturdy square bar table works.
- Here in Boston, lots of the Irish pubs have really low ceilings, but luckily they also have sturdy tables :-) BUT, be really, really careful. I stand and try to knock a table over before I put my 1/2 L1 on it. If at all in doubt leave it on the ground.
