I am looking for some more driver recommendations. Tapping the well of knowledge and experimentation here.
The Zaph 5" was an excellent recomendation. In my last build I used a planar mid which sounds incredible but is a real bastard to work with.
What I am looking for:
1. Easy to work with, easy roll off
2. A 4 inch or smaller
3. A 6 inch or larger
4. Low sensitivity is totally ok and nearly an asset because of what I want to do with them
5. Nothing about $300
6. Budget options (under $50) also wanted because I am experimenting with them
7. Minimal cone breakup behavior
Backstory:
My first build used a full range driver for the mid with just a single inductor high pass. It used a single high xmax woofer with only one inductor as its high pass. The tweeter was crossed after the full range with just a second order. So everything kind of rolls into one another. It sounds really good. It does not sound good if you crank the volume.
My experiment:
I want to try an MTMWW. Maybe a cheap one just for fun.
I want to use 2 mid. One large diameter driver. One small diameter driver. I want a very small tweeter in the middle.
I want to roll everything into each other with low order filters. I think I can do this using 4 woofers. I don't think I can do this if I use anything with bad cone breakup.
Basically I want to pass everything well within its own band. Long before it starts to distort. The last few builds I had to use high order filters as I was stretching their bandwidths if I wanted to stay in their lowest distortion frequencies respective to the drivers.
I am aware I will need high efficiency woofers since the mids will combine their range and be high sensitivity
I've been looking at some cheaper and some more expensive drivers. I am not sure which way I want to go.
The 18U Revelator appeals to me for the large mid
While not specifically a mid the Dayton DA175 7" also appeals

For the small mid I see a lot of Peerless full range drivers. Those might be good fits and let me cross high to the tweeter.
For an expensive option is the 12MU Illuminator and boy is that sucker pricey. That seems like a driver that I should maybe build up to over time rather than jump into right now.
Mid price there are a lot of SB acoustics options. There are tons of them and I'm not sure which are good and which are not.
Well, let me know what you have used with success and you recommend

Interesting. Are the two mids meant to overlap in the lower midband, but the bigger mid rolls of at like 2k and the smaller mid extends up to the tweeter cross?
I like the Scanspeak 10F for the smaller mid. Lots of options for the larger one, maybe a Satori MR-16P, or a Wavecor hard paper driver.

I don't really know yet. I was just playing around with a 4 way the other day and realized if I had drivers that were more well behaved I could gently roll them off into on another.
I was trying to get the full range of human voice with a single mid and sort of figured out the way to do it might be two mids. One bigger, one smaller, and then I figured I could MTM it for a more point source type of effect.
That is another thing I don't have enough experience to understand. I have heard the sensitivity of speakers playing 150hz doesn't really matter much. That the measurement is taken at 1000 hz or something so it doesn't apply. Its all about cone area. So maybe a 15/18" on the side is the way to go there.
This is all second order but I think I could rework something that was even more 1st order. Issue I ran into here was a high enough sensitivity woofer for the lows.
MMTMM is where you want to be with 1st order filters…….top and bottom woofers through a .5 inductor. Keep midwoofers in the 5-5 1/2 size class……no way to go larger and still hope for a 1st order tweeter. You’re gonna need a 29mm or larger dome to handle a 1st order cross.
That's the whole point of the second, smaller diameter mid. So that I can cross to the tweeter high using 1st order.... Also beaming issues...
different size drivers with extended 1st order overlapp...with distance you're gonna get some phase issues
I did see that even in the sims. I can get phase issues with the like tweeter and the large mid. Or the woofer and the smaller mid. I think I'd have to do at the very least a 2nd order for the tweeter and the woofer.
I've done two builds with the Scanspeak 12MU and it really is spectacular. Another option might be the Purifi 4.5"? Yeah, they're pricey but once you go Purifi, you might never go back.........

Fairly well behaved and full of 'features' for the price.
Audiotechnology 4H52 0613SD.
Breakup tends to be very well damped with the Mineral filled PP cones.

Maybe this Peerless 4".

I fear doing these types of things. I tried out a bag of Darjeeling 1st flush tea once. It ruined tea for me. Everything else is sub psr in comparison
Do these ship to the US? I have seen quite a few people use this brand on this forum but couldn't figure out where they were sourcing them.
That one is on my radar. I'm interested to see if all of these "new" Peerless drivers come back in stock and PE actually has stock and not the same "minimum order quantity 500 pieces"
Peerless has a ton of good stuff for more than reasonable prices that I want to try out. I'm using one Peerless 8" right now and it is a fantastic driver.
The Monacor MSH115HQ is a great midrange. Low distortion, easy to work with, work very well in MTM arrangements. They're very inexpensive to buy, yet I'd suggest box well above their weight. you can cross your LF to them anywhere from 250Hz on up with them in a sealed enclosure. Lower mids with them are very tight whilst vocals and other mids are clear, articulate and very detailed - you might consider tossing these in your short list.
This is the first I've seen those. I see a tweeter and midrange with 4 shorting rings each!
I would be curious of the cost to import if you do...
I was told a few weeks ago, that the website was not updated. Drivers they get in stock are available without minimum order. Drivers are not new designs, they are new to PE stock. I've owned a pair of the 4" for over 15 years I think. I was told that their intention is to keep Peerless drivers in stock. I suspect that it's difficult for PE to have all of them all the time, due to Peerless purchasing requirements. I was also told that factory lead times are about 5 months currently on some items. There's a lot of items due to arrive in May. Some of those were ordered in January if I remember correctly.
