Madisound might not be the only one to make the apparent mistake of classifying drivers by the overall frame size. In the case of most of Mark's drivers except the budget stamped steel frame CHN70, or the new resin frame CHS70 / Pluvia 7, the wider than normal flange causes some confusion.
Good point. It has an Sd a bit greater than the SDX7 so … lets start calling them 7". Easier to say, type …
The A12pw is certainly an outstanding woofer.

I've realized an issue with the 12PW is .. the frame size. At least for close pairing with tweets. I wish MA frames were normal size.
It is one of the things we have to give up to get the positive aspects of the basket. And it isn't a big deal if you XO low.

To get the ideal ¼ wavelength centre-to-centre it has to be lower than that.
With the wide bandwidth of the A12pw you do have a large range of possibilities.

Looks like things have drifted onto other subjects but I thought I'd throw this out there. I dont know how much the seas and SS drivers have changed since the dayton RS drivers came out but here is a link to Mark K's page of driver tests that had people freaking out about the dayton's perfomance.
Measurements
Its unfortunate that this site shut down. You can only look at two pages without registering at archive-org so choose carefully. If I remember correctly it was the rs225 that was the real shocker. The review of Zaphs drivers was pretty interesting too.

I suppose you have some on and off axis measurements to back it up ? Calculating it, membrane of that size starts to beam at about 2,4KHz.
You still didn't explain what you ment by "different driver types" regarding Dayton RS150 and Scan Speak 15W4531.
Yes, it isn't ideal for tweets. And then they've glued that (ugly)extra cover on the Alpair too. The best I could do apart from something drastic is to push the ribbon right up to the Alpair and make a cover to smarten everything up.
I considered that i may misunderstood your post. That's why i asked for clarification.
Much obliged.

I don't understand why they are very different kinds of drivers if they are often used in similar applications.
My thoughts exactly. Even their official ts parameters are similar and both of them would have been used in two way with the same tweeter xovered at roughly the same frequency.
I don't know of any other midbass from Dayton that is comparable to ss 15w4531. That is why i chose it.

scanspeak mid bass drivers FTW say I. ��
peerless drivers are easier to ntegrate at the top end but dont have thw bass. plus the ss sound so warm and sweet. ill take that trade.
Best,
Erik

It is not that useless as you imply but i am aware that because of shape of the membrane beaming frequency can vary. I haven't said it is impossible but i do have healthy dose of doubt. That is why i asked for measurements off axis (to at least 45deg).
I kinda like claims that can be proven. I see nothing wrong with that.

Zvu, I don't imply anything!
Membrane size is quite useless unless you know how "shallow" or "flat" it is....?
The use of question mark at end of sentence is a question, isn't it? 😎
Regarding measurements and claims to be proven, I agree with you. It's just I've seen measurements of Tangband's flat cone wide range drivers that show much better behaviour higher up than "normal' cone profiles.

Cool. I'd like to see those measurements too 🙂
Ofc, but question would be formulated something like: Is membrane size useless unless you know how shallow or flat it is ?
What you wrote is declarative sentence but with misused question mark.
Then again, this is the written word and it is a bit harder to understand precisely each other all the time since english isn't our first language - but we can try, can we ? 🙂

I don't know if I'm the best "audiophile".
But I am into build quality and doing things correctly.
SB Acoustics has the best build quality out there.
Better than ScanSpeak.
Usher, might be close to SB Acoustics also.
Well Skanning/Audio Technology and ultra high end, I guess might be even better.
SBAcoustics-tweeters
"Now, I've checked my most recent tweeter tests, and I can't find any tweeter displaying such low distortion all the way down to 1 kHz.
I've repeated these distortion measurements several times and find them consistent. This is what I get."
Do you know why this is the case?
Precision, attention to detail, expensive parts and build quality . . . and engineering; but many I'm sure have great engineering/design.
Wavecor seems to have the best engineering (home audio), most highly technical team, but I want the build quality. Also I like their 30mm tweeters.
If you want a "real system":
Home audio tweeter is okay, if you wish.
And then rest needs to be pro audio drivers.
Look at the guys who build speakers.
Their best speakers, according to them, are made from pro drivers.
But they are large.
