I just moved into an old house where we redid the kitchen and ran some
new wire for ceiling speakers in addition to our mains in the living
room. There was also some existing 14/4 CL2 cable run to the detached
garage. No conduit, just run through the walls to a small hole in an
outside wall and strung with some phone wires into the garage.

It is about 50-60 feet from my amp. This cable was then split into two
pairs for cheesy speakers in the garage. We like to entertain inside
and out, and replaced the garage speakers with a pair of JBL N24AWII
Northridge Outdoor speakers. Now, obviously with the long run to the
garage, those speakers are getting very little power. To get decent
volume outside, the inside speakers are way too loud.

What is my easiest (cheapest?) solution to bring up the volume for the
outside speakers?

Do I need another amp out there? Will a separate volume control for
those speakers do the trick?

Somewhere in the back of my brain I know the answer to this. I'm just
too lazy to work it out on my own!

Thanks for your thoughts!

This could be some pretty good speaker cable.

Not obvious at all. 14 guage wire has 0.0026 ohms per foot. Each 60' pair
going out to the garage has a total resistance of 0.312 ohms. The JBL
N24AWII speakers are speced for 8 ohms, which puts the maximum loss in the
cable around 0.3 dB which is negligable in this situation.

To get decent volume outside, the inside speakers are way
too loud.

More likely, your indoor speakers have a higher effective efficiency than
the outdoor speakers. The JBL N24AWII have 86 dB/w sensitivity at 3 feet
which is a tad below average. You don't say what your main speakers are,
but the average home speaker is probably more efficient then the little
JBLs.

However, the effective effciency of the little JBL may greatly decreased by
differences in how and where they are used. Your living room and your garage
may have differing acoustics and people may tend to stand further away from
the little JBLs when they are listening to them.

Hopefully, you didn't inadvertantly short the wires going out to your
garage, as that would radically cut efficiency even further.

What is my easiest (cheapest?) solution to bring up the
volume for the outside speakers?

Turn off or attenuate the sound to the speakers in the house, or provide a
separate booster amp for the speakers in the garage.

Do I need another amp out there?

Maybe.

Will a separate volume control for those speakers do the trick?

Almost all remote volume controls that are sold for this purpose can only
decrease sound levels, not increase them.

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. 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!

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.

Hope you find a good solution.

Running all three at the same time and getting adequate volume outside
is the goal. It sounds like a separate amp for the outside speakers is
the way to go.

I would purchase a used stereo receiver with a tape recorder loop. It
should cost less than $50. Now I'd run the tape recorder output of your
main receiver to the tape input on the receiver outdoors. You now have 2
choices outdoors: Any signal normally supplied by the new receiver, or the
same signal being played indoors, and the volume can be set independently.

I was wondering about using an old receiver, Norm. I already have an
ancient Radio Shack receiver that the old owner left in the basement.
It's been so long I don't remember about the tape recorder loop--will
the tape output from my main receiver always match the source I have
selected? So , regardless of whether I am playing the radio, a CD, or a
DVD, the tape output will get that signal?

Almost. Everything *except* whatever is plugged into the tape input
will go out the tape output. If you have a component plugged into tape
input it will not appear at the tape output. This is to curtail
feedback loops and every receiver that I've ever seen is designed this way.

If your receiver has a "preamp output" that will get everything. As for
the "slave" receiver, use any line level input (i.e. tape, aux etc. -
your Radio Shack box probably too old to have a CD inupt) Do not use the
phono input.

Yes. That's perfect. Take the "to tapedeck input" connection from your
indoors system, and run it to "from tape deck output" on the remote
receiver. They'll match up perfectly.
