Start with a radio that has Synchronous AM available which includes the R8A and B I believe.

While I have a few very high end stereo speakers they are poor for audio restricted BCB and SWLing and let in all the hiss plus emphasize all the higher distortion products out to 20 kHz and beyond. You dont need any more than 5-6 kHz capability.

My favorites are old vintage National and Hallicrafters 8-12" ones in good condition with the bigger ones for ham AM using BC rigs to TX or others modified to sound like the AM of yesteryear.

Some of the older K-I-Y outboard speakers that contain selectable filters do very well to get rid of rumble and hiss.

Another one that is not absolutely horrid is the Bose 141. It has the single full range speaker, but is ported to enhance the bottom end. That said, with a typical communications receiver, it sounds pretty OK.

I’m. It sure this is the way the OP would want to go but it works well in my experience. BobHeil suggested this on Ham Nation and in hamfest talks. Get an inexpensive audio mixer...I use Behringer...and the JBL Control 2P studio monitor speakers. I’ve inserted a BHI DSP unit between the mixer output and the speaker input. The BHI unit is adjustable and switchable into and out of the feed. Set the audio tailoring for weak signal stuff or with fuller audio for SW broadcast, etc. you can use headphones with this setup or the 35W studio monitors. I use this system in my ham station as well as my receiver-only monitoring position. When I’m done, just turn down the master volume control. It’s ready to turn up when you come back.

Synchronous detector, dsp white noise reduction and Sennheiser headphones makes for the best... oh wait, this is about speakers... never mind.

Basically if I ever find speakers that match headphones I'll buy them but so far, nope. Now if I was a contester and it was more about wearing phones for a very long stretch I might want to get serious about speakers.

I had a car setup that was just stunning for what I invested in it. It consisted of an AM radio of no particular provenance and a speaker of course. I built the speaker into an open-back box, no baffles of any kind, and just stuffed it up under the dash so all the cables and wires were holding it in place. It sounded quite good for some reason, I could make out all the lyrics of rock songs...

Where's the OP? Why doesn't he TELL us what he's settled on doing for speakers?

I have used Optimus, Minimus and center channel speakers and ALL work beautifully, especially for the price range.

But my personal favorite 'best' has to be the old Grove SP200 Sound Enhancer Communications Speaker. Originally around $200 or so, but I got one for substantially less than half that price... and it is just a fantastic speaker even without any of the features in use (treble, bass, notch, bandwidth, etc.). Using those features brings great, clean audio. But it's not easy to find and more expensive than the other types mentioned, and I suggest the center channel or Minimus speakers will be just fine for you.

But... will you please let us know what you've decided to use?

KD2E exhibited improper forum courtesy by not responding even once to all the great responses posted after he started this thread.  When everyone responds to help you, you should respond at least once in the thread to acknowledge responses from others.  People who actively provide great advise on these forums may remember your call sign the next time you post a question and solicit a response...by not responding to you.

I indicated my preferences a few posts into the original topic. Since then I've set up the Yaesu "triplets" (FR-101S, FR-101D and FL-101) in my lineup, connected an SP-101 and greatly enjoy full analog SWLing.

Another favorite is an SP-980. BIG cabinet. Nice bass response. Pair the speaker with a filtered-up FT-980 and it's very pleasant to listen to.

There are a number of "accessory" speakers in my inventory from various manufacturers but after having used most I'd rather get a good bookshelf-sized stereo speaker instead.

I do not think KD2E exhibited improper forum courtesy. The responses may be useful to everybody and he may only 'guilty' of having started an interesting topic. Btw I found military speakers very effective once the impedance is correctly matched. They may not have basses but are great for speech.

I wasn't thinking there was any breach of some forum etiquette. I just wanted to know what you'd decided to do! Smiley Thank you for filling us in. I imagine it's a fine set up for you. That's the main thing -- what it is/does for *you*.
