Re: Nearfield monitors

I have some NS10 Yamaha's and some Tanoy monitors that I've used with my K3, the NS10's drive a little better but are a bit flat for SSB, and a little to crisp for CW. The Tanoy's are too muffly with everything.. I find that the cheaper the speakers are the better they sound with HAM equipment. Don't get fancy with your nearfields.

Re: Nearfield monitors

I beg to differ, Any radio will show its true audio traits if it is
fed into a good wide-range speaker (or amplifiers and speakers).

The best sound I get from my K3 is when I connect it to the input of my
shack/office sound system mixer which has a wide range amplifier and
good high fidelity speakers following it. The amplifier and speakers
are flat from 60 Hz to about 15,000 Hz, and the speakers are AR-3s.
Should I want a better and smoother sound, I would bring in either my
set of Spectrum speakers or my Vandersteens No, I do not normally use
it that way - I just did it for a test!

The goal of speakers and amplifiers is to produce a true reproduction of
the input signal. If the speakers make SSB "a bit flat" or make CW "too
crisp", you can blame it on distortion in the amplifier/speaker combination.

Yes, I believe there is a place for high fidelity sound reproduction in
ham radio - speakers that have ragged response curves will not
faithfully reproduce the input signal. I will admit that for certain
purposes, like using a speaker resonance point to amplify your chosen CW
pitch may be an enhancement, that same speaker will make SSB "sound funny".'

As you might conclude, I enjoy faithfully reproduced sound (I compare
music to what I hear in a live concert), and I abhor distortion -
speaker/amplifier combinations that produce response peaks drive me to
distraction. Give me a flat amplifier/speaker response that is free
from distortions any day of the week - that is why I have invested in
good audio gear - peaked (or muddied) speaker responses drive me nuts,
even on my K3.

Try your K3 driving into a good audio system and it may surprise you -
the K3 is capable of "Hi-Fi" sound.

I was mostly put off by the wiring and amp effort. Laziness being the

I currently use the internal speaker or my Heil (hi Bob) Traveler cans.

YES! A few days ago, I listed several small loudspeakers that work well
with a K3. The marketing departments of the companies that make them
would call them "near field monitors" to get a higher price for them.
They came out of my stash of pro audio gear, and that's the way I've
always used them. :)

Re: Nearfield monitors

In reply to this post by Don Wilhelm-4

I'll just have to agree to disagree with you Don. The only amp that I'm using is the K3 amplifier chip. I'm not talking about hooking my K3 to a stereo system, or through a neve or SSL audio mixing board into a QSC amplifier here.. This is Ham Radio.. It's communications audio, and when you put a cheap speaker on it it tends to accentuate the freq. that the radio was made to deliver... 100Hz through 4KHz (if that).
My point was plain and simple, the NS10's which are probably one of the worlds foremost nearfield monitors used in the studio environment don't sound good using only the K3 to drive them, neither do the Tanoy's (yet another VERY popular nearfield monitor used in professional studios). This person didn't say anything about hooking outboard equipment, amps, mixers etc.. he asked if anyone tried using nearfield monitors with the K3.

Nope. The problem with cheap speakers is NOT limited frequency response,
it is BUMPY frequency response, which makes it harder to copy both
speech and CW. I know -- I've MEASURED a bunch of cheap speakers, and
that's what they look like, and it's how they sound. I've got good, near
field speakers hooked up to my K3 (main and sub-rx).

The shortcoming of most small speakers, including the ones you cited,
is that they have POOR VOLTAGE SENSITIVITY, meaning that it takes more
voltage to drive them than the K3 is designed to deliver. They are
designed to be driven by big power amps, not the low power chip used in
the K3, so the K3 doesn't have enough voltage headroom for them I
suspect that it is this is at the root of your dissatisfaction with your
studio monitors. But Don is entirely correct that the ideal loudspeaker
for a ham rig is one that has FLAT response in the speech range, and has
good polar response (that is, the response remains the same as you move
around in front of it. The fact that it has good low end or high end
does not matter -- it's neither a plus nor a minus.

Re: Nearfield monitors

This will be my last post on the subject because some people don't understand that I'm only trying to convey that you don't need 800 dollar nearfield monitors that come from a professional studio in order to enjoy the sounds coming out of your K3.
Yes, the NS10's and the Tanoy speakers require more drive in order to make them sound good. This is EXACTLY why I said that using them with the K3 as they are makes them a BAD choice for the reasons that I stated. They don't sound good.

When someone asks "how do Nearfield monitors/speakers" sound on the K3 I think Professional speakers hooked up to the K3, not consumer hi fidelity speakers.
I'm sorry but if you know anything about the NS10's you should know that those speakers have a 2 kHz bump of + 5 dB and low frequency drop starting at 200 Hz they “open” the frequency range with a midrange-based response that exposes the most problematic and worst-sounding frequencies. In your consumer hi-fi, the EQ preset that makes most music sound “better” (”Loudness”, “Rock”) is exactly the NS-10 frequency response, flipped upside down… Perfect for monitoring, but fail (as you said) under low voltages.
A flat response from a set of speakers would NOT be ideal to most people. Consumers are used to hearing their audio "colored", with EQ, Like they do out of their home stereos and car radios with their 6 speaker systems and separate sub woofer systems. If you were to have a perfect flat response speaker and put someone in front of them you would probably get the reaction from them that they sound "dull", or too bright/crisp (assuming the top end 8-20KHz could actually be flat).

You missed my point about "cheap" speakers.. I didn't say that they had limited freq. range.. I said that they tend to accentuate the freq. that the K3 has to offer (not attenuate). As in they bump the 1.5KHz voice portion, and 300 to 500 Hz CW areas. Exactly what people want to hear when listening to a communications radio.
Cheap speakers, and I'm not talking about 10 dollar computer speakers.. You people don't always have to be so literal... aren't what I was talking about. I was referring to Cheap speakers as in 30 to 100 dollar speakers would be more than enough to enjoy all that the K3 has to offer. There's just no need to put Hi fidelity speakers on the K3, with or without an outboard amp.. I'm sorry... CW just isn't going to sound any better from a 1000 dollar speaker. SSB may, but why bother? (man I almost said it's just glorified CB radio anyway... I'm glad I didn't do that, the flames would have never stopped)
There comes a point where a 100 dollar speaker will sound just as good as a 1000 dollar speaker. Besides, most people could never hear the difference if they were given the opportunity. If it were up to me, I would just go out and get a really nice pair of headphones if you really want good sound when it comes to SSB. I'm sorry, but I'm just trying to be practical here... I wish some of you would try to be from time to time too. Nuf said.. No need to respond.... We'll just have to agree to disagree.

Ham marketing is no better. As evidence, I submit the advertising of
almost any antenna company, especially those with magic off-center fed
wires, all-band verticals, and wierd collections of aluminum, the all
time champ of which is the Isotron.

And for more crazy pseudo-science, do a search on phrases like "ground
loop" and "fundamental overload." Both are still a mess in the newest
ARRL Handbook, which is why I had them take my name off of the EMC Chapter.

assembly to exceed the performance of the originals. The mounting
bezel is then polished for an elegant appearance. The paper cone,
chosen for its musical character, is custom designed & crafted using
the finest New Zealand pulp with mica fibers added for lighter weight
& rigidity. The cloth surround is made in Japan to exacting uniform
thickness tolerances. The Top Plate and T-Yoke of driver are made of
Sumitomo 1008 low carbon steel enabling the highest modeled flux
density in the gap. The magnets are Y- 40 GRADE (MIL-SPEC) yielding a 43oz "

EACH & Every sentence makes me snicker...
what ever happened to an old 5" utah,,,,radio speaker,.,,,

we have come a long way .... :) in no particular direction.....

Bob Greiner, an EE prof long retired from Univ of Wis at Madison did
some excellent science debunking exotic wires 30 years ago, which he
published as an AES paper.

The executive summary -- for virtually all real loudspeakers, it's all
Ohm's law, and nothing else matters. The sole exception would be an
exotic type with a tweeter having very low impedance at high audio
frequencies.

It's worth saving this reference when you encounter RFI to an audio
system that uses esoteric cables. :)

Re: Nearfield monitors

Yes, it is all about Ohm's law, but there *are* some advantages to the
"exotic" cables 1) they are usually made with large diameter wires,
satisfying the Ohm's law requirement even with higher power amplifiers;
and 2) they are quite flexible which makes running them in tight places
easier, and they will stand more flexing before the wires break.

Other than for those advantages, any piece of wire of a suitable size
for the max power involved will do the job - but I do use the lower
priced "exotic" cables on my home theater system for the reasons stated.
