I won't get involved in a cap thread but you are a traditionalist and I thought I would mention something you might want to consider. You can negotiate a volume deal with Chris1thisone, for original tweeter rebuilds and sell all those AR9 tweeters. At current prices you would more than recoup the cost of the rebuilds which I believe are around $70/pair. There are numerous advantages to this approach for someone who just wants to get things back to normal.
If you want more tweeter power afterward just keep the Microstats connected.

No idea but if you are of the opinion you would continue as is if the thumps weren't occurring you might want to isolate the speaker with thump and focus on that. Then throw one of your spares into the stack while you locate the exact issue.
Just guessing.
I can tell I would focus on keeping the music going rather take everything for major rework.

Good advice, thank you.

And if the same thump is occurring in more than one speaker it is not the speakers. It is just too improbable.

I googled and can't find anything on the Sherwood. It doesn't appear to be current product. I haven't said specifically in the thread but I am already using two Crown xls1002s with their built in crossovers. Is the Sherwood a similar product.
-
Ok. I found one on ebay. There was no operating manual so I am not certain it would do the job but it has now been surpassed by amps with DSPs integrated. For example,The crown xls series allows frequency selection in 1/12 octave increments per channel between 30 and 3000 hz. Crossover modes are HIgh, Low and Bandwidth. It is a very cool product for a surprisingly small price and 5 year warranty. Combined rated power available at my rated impedance is 900watts per channel which is coincidence. I just needed something that could carry a 2 ohm load. And then I got another one to isolate the AR woofer.

I did not want to divert the thread from cones vs domes and it was tending toward a personal advice column with me seeking answers I am not sure others would care about.
I am not a speaker builder. In the simplest form my question is which cone driver size will give max dispersion in the 200 to 4000hz range?
My reason for asking can be found in these threads.

There is no need to read the whole thing just look at the photos but, you should know that all 8 mid&tweet drivers per side are equalized and have their combined output balanced to the woofer. This is not a bunch of speakers running wide open to get the biggest, loudest sound.
This started out as a powered subwoofer project and morphed into this hybrid. I have standard setups of AR9s and 3as which I like but I now listen to this system more than anything else. What I intend to do this week is simplify it. I will eiminate the sound of the AR58 mid and tweeter by using a second Crown DSP amp to turn the 58 into a woofer only system. The satellite stack configuration will change and be rebalanced and equalized. If I don’t hear what I expect then I will restore the system to its current klugier config and move the amp to another system.
The satellites are 5.25” Bostons but they are so cheap and easy to find that I have been thinking that perhaps a 6” would be better to crossover even lower and get the woofer completely out of the female voice range but I didn’t want to sacrifice dispersion for a lower crossover and that is really the root of my question to you.
I have never liked the beaminess of satellite speakers but know they can be competent performers above the mid bass level. My original idea was to do this with powered subs but they are too tricky for my taste and quite by accident I found this approach can be very effective if you have the spare hardware sitting around.
I have done internet searches looking for others trying to accomplish the same thing with no luck otherwise I would be trying to talk to them. I have found plenty of diy line arrays but that is not what this is. If I am trying to emulate anything it would be an LST.
Anyway, I think I have explained why I am asking and only had the single question about driver size and dispersion.
Thanks

When you we are after different goals, do you mean "you and I' or "We and They"?
-
People who are in the wide dispersion vintage AR camp are "illuminating" their probably
too small (in my opinion) rooms with sound. I am not in that camp as I believe that small
rooms are bad for good sound. I do all critical listening in the sweet spot and I listen to a
lot of vocal performers who I want placed center, between the speakers. I listen with
speakers 3 or more feet from the wall behind them. Sure, I also listen well off axis when
the music is just for background listening. I don't expect that I'd be an AR LST lover, since
they also "illuminate" the side walls though I've not had a pair in my home.
I think you and I are after different goals.

Got it. The odd thing about this satellite stack is it has a sweet spot and seems expansive. The speakers are not wide dispersion and I would like to see how it would do in a larger room to check for beaminess. I must say being forced into a sweet spot has been a new and pleasurable experience though don't like being nailed down to listen.
