I bought The Tivoli Audio Model 2 last week. It came with an additional
speaker. I also bought the Tivoli Audio subwoofer speaker.

However the subwoofer speaker is not very loud. Before I bought the
subwoofer, I thought it will work well giving nice deep tones, but I can
not hear it very much even when I have the vol. all the way up.

Also their is no tone button. I learned that a tone button is good to
use when trying to hear stations that might have a near by interference.

Pretty good bet this is all by design.

First, the Tivoli/Kloss radios use some pretty heavy audio equalization to
get "big" sound out of small speakers. Allowing any degree of manual
control would allow the user to defeat the intentions of the designer, and
so it's probably omitted as part of the design.

Second, the AM section on these radios is perfunctory at best. The antenna
is a simple spool of wire inside the cabinet, sensitivity is mediocre, and
selectivity pedestrian.

This is a program listener's radio, not a DX machine ... and one whose
design is heavily weighted towards FM performance.
