: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".

== L1 Classic ==

NOTE: The impedance issue affects the {{Model I}} and {{Model II}}. The {{Classic}} uses separate amplifiers for the top and bottom sections of the {{L1 CR}}. 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}} 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?

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.

;Note - if you are using a B2 connected directly to your L1® Model II Power Stand

You can still run your system with only the lower half of the Cylindrical Radiator® but plugging in a ¼ inch jack cable to the Bass Line Out will not affect the output to the B2. You will likely want to set the B2 Bass Level switch to the (-) minus position, and turn down the bass at the source ({{T1}} or mixer).
