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? Are they good?
Is there a recommendation from Elecraft or any wise audiophile?

Re: 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).

The West Mountain Radio powered COMspkrs are wonderful. No RFI problems at all.

Re: 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.

Thanks,
JP

Re: Loudspeakers for the K3

In reply to this post by OE5CSP-Chris

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.

Re: Loudspeakers for the K3

I've posted this a year ago but want to repeat. Probably an over kill but I
run the K3 into a stereo amp and then to book case speakers mounted on the
wall and pointed down at me. Wonderful audio that I never tire of, even
after many hours on the K3. I've used these for over 15 years and find them
the best. No RFI. Phil

Re: Loudspeakers for the K3

Radio Shack sells two reasonably small stereo speakers. They are black and
have the name AUVIO or KLH on them. The dimensions are 4.75"W x 7.5"H x 4"
deep. They match well with the K3 and are moderately priced. They match
well to the K3 and sound great to me. I have two sets of these for my two
K3s and am pleased with them.

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.

As an audio pro, I have a few observations. The speaker amp in the K3 is
a fairly small one, so outboard speakers should be either fairly
efficient or should be amplified. Most home stereo speakers have fairly
LOW efficiency, but most speakers for use in public address systems, and
most speakers designed for communications use have fairly HIGH efficiency.

For most serious operation I use headphones, but for casual operation I
use outboard speakers. On the radio I use the most, they are a pair of
very efficient, very good pro speakers that have long been
discontinued. On the other radio I have a couple of miniature cube
speakers designed for communications use. They all work fine.

Voltage sensitivity is expressed as dBSPL for one watt at one meter, or
for 2.828 volts. The most efficient small speakers you're likely to
find will have this spec in the high 80s. SPL is Sound Pressure Level
with respect a standard acoustic reference level. In the near field,
sound decays at 6dB per doubling of distance, so at 1/4 meter, it will
be 12dB louder than that number with a one watt sine wave, about 10 dB
less with speech.

Re: 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.

Re: Loudspeakers for the K3

In reply to this post by OE5CSP-Chris

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.
