My Icom R71A audio improved immensely by the use of one of the add-on
computer speakers that has really great low frequency response. That coupled
with the outboard JPS NIR-10 Noise/Interference Reduction unit
makes it a real joy to operate.

The speaker is a about a 3x5 inches with a heavy magnet and a tuned port at
the bottom for some reason. I an no audiophile for sure. It just sounds
great.

I will appreciate any insights that can be offered on these modifications
in
helping me decide if it is worth it to add them.
