Sonido fullrange driver thoughts?

So I’m not very good at reading specifications, But from what I can tell, the SWR 300/FC should be pretty happy making good bass around 30htz, which is pretty nice!
95 db efficient is also pretty nice!
I’m also guessing that it would prefer a large box 📦.

A question for Istvan…. When you make a New driver like this one, obviously you test it and then Model it with Software… but do you also physically listen to it in a box/ baffle before releasing it for sale?
If so, what do you notice is the difference to the smaller drivers?

Thanks 😊 John D
 
This result is not final yet, there are still some improvents to be made with this driver. Yes, that's right, I don't listen to the new driver in box (such a number of boxes simply cannot be placed in SONIDO). I usually model using software and my many years of experience allows hu to determine the best option of the box for a given driver based on simulations.

I noticed I am not big fun of whizzer cone.
It changed sound stage a bit natural but it could high frequency expansion and defusion worse.
Just only my preference and opinion.

I usually recommend these drivers for small monitors, for example these (1.and 2. figure) For muself, I built a box like this with these drivers (figure 3.) to improve the sound of thr TV. Now the TV has excellent sound.

I guess everyone hears differently and has different expectations….. and maybe the box has an influence on the sound too…
Personally I love ❤️ the top end and “air” I get from my drivers, 250 SWR F/C ( much nicer than my SB Acoustic drivers).

So, I’ve been listening to my new SONIDO FWR250FC for two weeks!
Sadly probably not much more than 15 hours.
Speaker “Run In “ is controversial, but after running in Six “full range” drivers, I’m pretty sure it’s real.
Anyway, at the moment I can’t think 🤔 how my music could sound better! ( I have been there before though, it’s true!)

Hopefully in a few days I will have my new boxes 📦! These are FAR BETTER than I imagined though!

Sorry for the lack of explanation,
SB ACOUSTICS SB20FRPC30-8/ paper driver!
It’s a really good driver for the $$!
$175 AUS delivered. In the right box it will equal commercial speakers from $2K to $10k AUS!
IF you want better and you can Probably Afford it, Look at SONIDO drivers.. you will get better sound much faster
