I tested the tweeters tonight. If you like the 1 E string and the 2 B string ringing out strong, this sound is for you!
I can't take them myself, but everybody has their own taste. They are easy to add, and I can see them as an option, but I will never use them.
In fact, if you want to make your guitar sound even more tinny than the standard high string tinny, these tweeters are right up your alley!
Sorry, could not help it! 🤣
Acoustic Guitar Magazine tells me the digital version including my Ad will be out Monday, stay tuned!

I regret not putting screw tap drill holes in with the CNC machine at work, for body and soundboard. Positional accuracy is 1/5 the thickness of a human hair (.001"). My basement shop is pretty much the opposite of CNC work equipment. 🤣
I put them in the body, no problem, but how to match the soundboard perfectly?
Measure and transfer to a temp board, drill though, then assemble and check accuracy. Not perfect, so open the holes to the correct location, but then any offset holes are too large. Then take a good soundboard that will be used, overlay, and transfer the holes with a punch. Then drill a small hole and check positioning to the body with a series of paper clips. All looked good except two holes, correct those locations by hand, then have perfect locations and let the drill rip. Assemble good soundboard to body and everything is perfect. Old School can work very well!
Art - I found one one of your past diyAudio threads from back in the day, and you don't want to write a book? That was one fascinating chapter my friend, you should do it, or maybe Tom Danley? Somebody should do it, I would buy it!
Reading in peace is one of my favorite things to do, no politics, no people talking to you (hey I like people, just good to have a break at times). Sure the sound engineer technical issues would be great, but I am also talking about the stories of sound, how much it has changed, how complex it really is, how much music has contributed to the lives of all of us. Have you ever met anybody that says I don't like music, everybody loves music! How many people would argue with that, not many. It is pretty rare air to find a field of art or life itself that everybody loves.
Speaking of loving to read in peace, playing a musical instrument in peace is even better. Yes playing with others is of course fantastic, but playing by yourself for hours is pure meditation, so good for the brain and the soul.
Today I confirmed once again the beautiful balanced sound that I love coming from my not so great looking guitar, what a joy. I was listening very closely as I played for about 90 minutes. Very warm low E string with the bass up just to 3 on the amp, strong mids, beautiful brilliant highs. Stop playing and knock it out slowly on every string, you can sure hear no string powers over the other, at every fret up to twelve, love it!
Hoping for good results Monday after the Acoustic Guitar Magazine digital Ad. Will my Website and YouTube get big hits? I hope so. Will I get a not so good response? Maybe. Who knows, we shall see!!

The perceived direction of origin of a sound is dictated almost entirely by the sound that arrives first. This precedence effect, also known as the Haas effect, also tends to emphasize the perceived level of the first arrival sound.
The direct string and tweeter's sound arrives at your ears around 5ms before the 5 foot long horn sound.
Since you can't retard the tweeter's arrival time to that of the horn, you may need to attenuate their output to less than the horn to achieve a better "balance".
I've encountered many people that absolutely hate certain genres of music, and will vociferously complain it is "too loud" even when played at a lower volume.
I know one guitar maker that seems to dislike the music produced by the two high strings 😉

More work required on the tweeters? That is a definite maybe...
True story, you can include me in that, I should say everybody loves THEIR favorite music.
OK that's pretty good... 🤣
I was going to say something, as Joe made no mention of how the tweeters got connected up to his amplifier's output. Series? Parallel?
Crossover? (Where in frequency). Specifically to your point; was the driver sensitivity of the tweeters somehow matched to that of the original speakers?
Joe, one time I had a friend from work bring over his home-brew speaker to do some pink noise testing. Found immediately the tweeter was operating waaaayyy louder than the woofer in that box - and fortunately there was a control on the back for it. I had to turn it down almost all the way to get it to match in output level. He told me he had no idea that was the case and simply thought that was how it was supposed to sound - with the tweeter level turned WFO..
So, without an FR plot - noting your perceptions - I'd have to assume a similar situation with your tweeters; that they are far more loud than your woofers through whatever amplifier connection you made and of course detract from, rather than add to, the sound quality you already have - because they are so "in your face" loud.
I'd say try it again, but this time with a level control you can take all the way down to zero. Bring it up until you can just hear them. How's it sound now?
You CAN delay the tweeter's signal, but it would take an ADC, digital delay and DAC, (the ADC and DAC may give the needed delay by themselves), but that may be more electronics than you may want to put into this. OTOH if this is going to be manufactured in large quantity (which I presume is the idea of licensing the design to a manufacturer), I would consider doing this.
JJ - I wired in parallel, trying series might be worth a try.
benb - yes my hope is to sell the IP or do licensing, so of course improvements can be made by people with more resources than myself.

That would drop their relative sensitivity to the main speakers. Any crossover info to share? There's got to be at least a capacitor in series with the amplifier connection, right?
Car audio has multichannel DSP boxes that could be used for this tune-up, if working with RCA connections to and from the box is easier. Guessing something like https://www.ebay.com/itm/134176741934 for <$100. Others probably know more!
JJ - no crossover used, might be required for sure. My full range speakers go up to 20k...I am interested in the idea, on my to do sometime list. 🤣
AGM digital Ad released. This is for subscribers only, technically you can email and copy the link, but to stay faithful to the wishes of AGM I am just pasting a pic here. My website has 1,300 new hits and it has not been a full day since it was released yet. 😎
Well, yeah. You're essentially designing a speaker and if you want to add an "extension" tweeter to your existing full range design, you may want to look at how others did it. Info somewhere here in diyAudio, I'd bet.
1st step is choosing where to "cross" frequency coverage from one driver to the other. With the car audio dsp box, that may be as easy as turning a knob; same company has a better one (I think) with what looks like an LCD display and a knob, which I assume work together to select and set parameters. With that, you can just run through settings until you find one you like by how it sounds. Hopefully that translates into something realistic for the tweeter drivers, in terms of what they can handle and not be destroyed.
I looked and the one with the LCD does just that...for $129. 2 in and 8 out RCA, with each output having full speaker crossover db/octave slope and level - plus the myriad of other functionality necessary to sell - I assume.
Nice tool for the audio toolbox, even if you just use it to tune up your 2, 3, or 4 way speakers in stereo and implement what you've determined to be the best sound in a different way electronically. Dont know if it does "compression".
It runs off 12V, which means it could be part of a portable pedal board for an outboard support electronics system for your guitar. I went to a different open-mic last night; one guy with a giant pedal board was apparently a looper track layering specialist. His talent at it certainly supported lugging that maybe 1 meter wide board around...

It would be very nice of you lived down the street from me. 🤣
Yeah, I need to work on that, thank you! Acoustic Guitar Magazine marketing department update to me: "Your Ad has 1400 clicks in just 24 hours!!! That is a REALLY good response to a Featured e-News story!!! CONGRATS!!!" Hopefully I have their attention, one can hope!
Of course I need to post some Rosanne Cash music. Man some of the early YouTube videos sound really terrible. I have no doubt the sound was great live, just did not record well, for whatever reason, and I am sure there are many.
I think this link (audio only) is excellent, with Emmylou Harris and a great band. Probably a bunch of great Nashville session musicians, top shelf!!
There is a beautiful old church in town, and my friend does sound there. We are going to play my guitar with a mic or two on the horns and into the P.A., long overdue to see how this sounds. It can probably seat about 300 people, not big, but very high ceilings, built in the late 1800's, should be interesting!
My fav is when Les Paul told Bucky he started out as a country guitar player, and Buck said "I can tell" 🤣
I remember the church my father took me to when I was a kid was an acoustic mess. They had two rows of support columns running down the length of the hard, bench seating and each column had maybe an 8" open back circa 1950s general purpose PA speaker hanging from it. No way was there any delay from the pulpit mic to the first speaker, then more delay to the second - the sound came out through them all simultaneously. Of course, I entertained myself at the time by listening to how it sounded, versus to what the fellow was saying. The organist and choir was at the back; they apparently didnt need PA support.
Sometime later, they got a couple PA columns hanging from the first two supports; I assume disconnected the remaining speakers, but maybe not.
I'd wager the construction of any church built before there was "sound reinforcement equipment" was designed with the acoustics of the place in mind. Specifically with the idea of giving a sense of "authority" to whomever is talking at the front. Perhaps play your FHAG up there, with no miking nor PA and see how that sounds.
I've no idea of what they do for sound in churches these days, other that I can see they're going as elaborate as they can afford, simply by noting what they sell off in the used market. Some of them must be like going to a rock concert every Sunday - minus the drugs and drinking. Particularly in this day and age, where it takes high level of entertainment to hold anyone's attention.
