Thanks for the detailed info, Arny. The indoor speakers
are more efficient. We have a pair of JBL SP6C speakers
in the ceiling and our mains are JBL Studio Series S38.

Stereophile gives the efficiency of the JBL Studio Series S38 as 91 dB/w and
states that they consider it to have relatively high efficiency.

Other sources give the efficiency of the JBL SP6C speakers as 88 dB/w

Both are greater than the 86 dB/watt sensitivity of the JBL N24AWII
Northridge speakers.

If you have both the S38 and SP6C running at the same time, their composite
efficiency is even higher than the more efficient of the two.

I will check my connections out to the garage speakers
again to be sure. The speakers are mounted outside the
garage to feed sound to the back yard, so, yes, the
acoustics are quite different. I thought the length of
that run would make more difference. Thanks for the
technical confirmation that it does not!

Hope you find a good solution.
