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). 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Jim Brown Sent: Sunday, October 16, 2016 3:18 PM To: [email protected] 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. 73, Jim K9YC On Sun,10/16/2016 3:02 PM, MaverickNH wrote: > So what's the verdict, High-Fidelity or HAM-Fidelity? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
