Take a stiff card, book or even your hand and hold it at a 45 degree angle
behind the speaker and against the top of the K3 so the sound is bounced
toward you and notice the difference. It's dramatic!

Back in the K2 days, many hams folded some stiff card or paper to make such
a deflector to tape to the top of their rigs. (Most of us, like me, used
headphones so the issue was moot).

Subject: Re: [Elecraft] Speakers - Optimal Frequency Range?

What matters is smooth (flat) response from about 200 Hz to about 3 kHz as
heard at the ear of the operator. The laws of physics dictate that
uniformity of high frequency response is limited by diaphragm size -- the
larger the speaker, the worse it sounds off axis. The speaker built into the
K3 is a nice small one, so it has pretty good off axis response, but it
faces straight up. In most shacks, the highs bounce off of nearby surfaces
to get to the listener. A front-facing loudspeaker will have flatter
response, but takes up more space on the operating desk.
