=== Trouble Inserting / Removing Cylindrical Radiator® ===

Check the screws shown here. Make sure they are tight.

== Bayonet ==

=== Adjusting the Length ===

The Bayonet can be adjusted for easier mounting/dismounting with lower ceilings.

Newer L1 Cylindrical Radiator(r) loudspeakers have bayonets with three holes. With the upper L1 on a table or floor, you can easily unscrew the two Phillips-head screws from the Bayonet and reposition the Bayonet so that it does not protrude as much out from the upper L1. This gains you an extra inch of space when mounting/dismounting the upper L1 in places where the ceiling height is less than ideal.

== Lower Half Only? ==

Q: Can I run with only the lower section of the {{L1 CR}}?

A: From a technical standpoint it is safe to operate the system with only the lower L1, however the spatial and spectral performance of will be greatly reduced, so this has only a very limited application.

=== Correcting the Tone ===

Try inserting a ¼ inch connector in the Bass Line Out of the Power Stand. This will cause the internal logic to reduce the Bass output, and this should give you a better overall tonal balance when running with only one section of the {{PAGENAME}}.

For very detailed notes about this see [[Half Stack]].

== Tilting the {{L1}} ==

For best results you want to have the audience within the zone of sound parallel to the {{L1 CR}}. That is, you want to position the {{L1}} so the audience is within the seven foot high wall of sound it projects. If you are on an elevated stage, people above or below the {{L1 CR}} will not be in the coverage area.

Line 87:

:On the other hand we are manufacturing to very tight specifications and tolerances. One L1 is virtually indistinguishable from the next one, so it's perfectly ok two swap speaker and power stands.

=== Damaged Connections in the {{L1 nl}} boot ===

== Dents in the Grilles ==

Question: Can I remove the Grilles to repair a dent?

:''Since the system has integrated controller/limiter/protection driver failure is very unlikely. All drivers are front-loaded, i.e. '' you simply need to remove the grille and then you can simply unscrew the driver. The only part that requires some care on the L1 is getting the grille back on, since its fairly large and needs to properly seated inside its gasket.

Summary

: Everything I could find on this (going back to 2003) suggests that on the early L1® Classics it was possible, but tricky to remove the grilles, but it was also problematic to get them reseated properly.

:With regard to "adhesive tape" I could not find anything written by Bose in these forums about the method by which the grilles are secured to the Cylindrical Radiator®s.

:The Model Is and Model IIs are built differently than the Classics and in December 2007 <br>MikeZ-at-Bose said "the grill can't be taken off without destroying it". [http://bose.infopop.cc/eve/forums/a/tpc/f/3976055944/m/2801027415?r=6541037415#6541037415 source]

:Since then Bose has been silent regarding removing or replacing the grilles and details on how they are affixed.

:Ken-at-Bose has said <br>"If you'd like us to help you with the dented grill, you must call our service folks." [http://bose.infopop.cc/eve/forums?a=tpc&f=867107664&m=3741079065&r=6781045165#6781045165 source]
