Default 4" midwoofer for mini 2 way

Hello guys!

I have some speaker's cabinets and want to make budget mini 2 way monitors. Volume is about 4L. I consider right now some 4" speakers for use in that project:

- midwoofers Dayton RS125-4 (8), Dayton RS125P-8. I would be grateful for the feedback from those who had the opportunity to compare them. For a long time I wanted to but never used speakers with metal cones.
Also consider SB12PAC25-4. There are not many reviews. Cheap. The parameters are also good. But plastic basket is ugly.

On HFreaquency I consider DAYTON ND25FA-4 and ND28F-6. I have not decided yet. Because of the cabinet, a tweeter with a flange diameter of 66-75mm is needed.

Looking at the RS125p-8 also. Many things to like, and parameters suggest it cd be used in a mini TL
For a small format tweeter u cd try the little tangband 'ceramic'

Yep. But dip in 2KHz region looks not so good. RS125 is more linear in working band.

I made 2-way with Seas CA12RCY and Morel dms30s and it sounded amazing for its size. Crossover point was at 2.4KHz. They show up on e-bay once in a while dirt cheap. I've bought mine for 55/pair.

Agree, its regular price is ludicrous for >30 year old driver construction. Last revision was going from square to round basket. Everything else remained the same. But the story is the same for every scandinavian speaker manufacturer.

What do you think about metal cone driver? What is your experience?
I want to try from one point of view. But I'm afraid from other side especially taking in account numerous fears about ringing...

I absolutely love metal cone drivers. They do need extra care with the crossover but they sound great to me. Lack of any aberations in csd untill the breakup is quite perceivable. With 4-5" midwoofers ringing is almost always over 8KHz. In my two way with Seas L15 ringing is -35dB on axis and -45dB only 10deg off axis. I don't know if anyone can hear it but i certainly can not.

Seas have paper versions CA15 and ER15 and they are easier to work with but they do not sound so natural as L15 does.

I'd always look for metal cone midwoofer before any kind of plastic. I thought very high of paper cones and they do have their place (woofers and pro speakers) but now i'm all in for metal for home speakers. If not metal, my second choice would be kevlar or fiberglass.

They sound metallic.
And have a cone breakup. This needs to be suppressed.
