Re: [Elecraft] Loudspeakers for the K3
I finally bought the JBL Control 2, and I want to report back to the group what I´ve found out so far. The sound is excellent. I had to find a sweet spot and fiddle with the volume control on the speaker to get rid of hiss and noise and I was able to reduce it to almost zero.I can only control the volume with the K3´s af gain, otherwise I get heavy noise from the JBL speakers.I´m also getting a bit of rf into the speakers, even barefoot, but it´s not a lot.If I can solve the problems I will keep them. 73,Chris-OE5CSP -- View this message in context: http://elecraft.365791.n2.nabble.com/Loudspeakers-for-the-K3-tp7472583p7555815.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Loudspeakers for the K3
I am using the speakers from West Mountain Radio mentioned several times in this thread and others regarding speakers. I find they have a nice cut for ham radio, at least for my ears and setup. Reducing highs are cut nicely and they have a good response for even dx if I pick up the volume on weak signals. But like you Jim, if I'm prepared for weak and crowded conditions, my headphones are on. Then only issue I have with the West Mountain speakers is that the volume is unbalanced a bit. The primary speaker (the one with the power and controls) is louder - noticeably. This isn't an issue for simplex QSOs but has me adjusting the volume/balance for split operations and diversity. These speakers have no balance control. Not sure if this is my pair or a characteristic of this design.

[Elecraft] Loudspeakers for the K3
I´m currently using a pair of old TV-speakers and I´m still looking for good speakers.I´ve found the Dierking 40w speakers(http://www.eurofrequence.de/lautsprecher/)in the internet.Is anybody using them with the K3?

Re: [Elecraft] Loudspeakers for the K3
Good morning Chris - I do not have direct experience with the speakers mentioned in your post, but I use a pair of JBL Control 2 powered studio monitors. They are very accurate and, perhaps most importantly, do not seem to radiate detectable RF (or be susceptible to it). http://www.jblpro.com/catalog/general/ProductFamily.aspx?FId=64MId=5 73, Mike Alexander - N8MSA amsct...@comcast.net - Original Message - From: OE5CSP-Chris hans-christ...@gmx.at To: elecraft@mailman.qth.net Sent: Tuesday, April 17, 2012 3:00:29 AM Subject: [Elecraft] Loudspeakers for the K3 I´m currently using a pair of old TV-speakers and I´m still looking for good speakers.I´ve found the Dierking 40w speakers(http://www.eurofrequence.de/lautsprecher/)in the internet.Is anybody using them with the K3?

Re: [Elecraft] Loudspeakers for the K3
Hello Chris, I do not have any experience with the speakers you mentioned. Hopefully another person will have information for you. The JBL speakers that Mike mentioned are indeed excellent. I first learned about them when they were recommended to me by Bob Heil. If you use a pair of them you can take advantage of the K3's various audio effects. Regardless of the specific brand and model, a quality set of speakers (or headphones) preserves the fidelity of the audio from the rig to help dig that rare one out of the pile or QRM.

Re: [Elecraft] Loudspeakers for the K3
I'm using the Inland ProSound 2000 multimedia speaker system. AC cable, no wall wart. Signal connector is mini-phone and fits the I/O firmly. Stereo AFX and Diversity image nicely with speakers about 30 apart. Running barefoot right next to the K3, I've never had any interference. Footprint for each speaker is 3.5 x 3.25. WalMart has these speakers for $10.84 (I paid $6.99 at MicroCenter about 2.5 yrs. ago). The specs say 3.6W x2. I have the volume set at 50%, and the volume on the K3 at 25% and its just right.

Radio Shack sells two reasonably small stereo speakers. They are black and have the name AUVIO or KLH on them. The dimensions are 4.75W x 7.5H x 4 deep.

They are black and have the name AUVIO or KLH on them. The dimensions are 4.75W x 7.5H x 4 deep. The Auvio S-PRO4 are Radio Shack catalog number 40-016 and list for $39.99 on-line. They appear to be in stock in most stores in this area. The KLH versions are no longer listed on-line. However, there are a large number of small bookshelf speakers - often marketed as satellite speakers for home theater systems - available for ca. $40/pair from many sources. A few months ago I picked up a few surplus communications speakers (about 70 mm x 60 mm x 35 mm) from cellphone handsfree kits for around $5 each. They make outstanding speakers for the K3 as long as you're not trying to fill an auditorium. 73, ...
