What Is Full-Range?

[CarlosT]

I just bought some little Vifa 5.25" and they have good response clear on to 5KHz and really beyond if you look at these specs.

Would one consider this full-range? What are the critical high frequencies? Would a little woofer like this handling it all not sound good?

Not full range for me. I'd like to believe that I can still hear to 15kHz, so a driver has to be reasonably flat to at least that frequency.

Looking at the Vifa's fr plot, the response is falling pretty fast beyond 10k. I don't think that is "full range" for anyone, unless you suffer from severe hearing loss.

I believe that is what we could call "widerange" 😉

I'd call it what they do: A mid-woofer

 

[tinitus]

Yes, it probably is a midwoofer and wont reach 10khz either 🙂

That would be me... I have a 6 element line array like that on each side of my TV... And it needs a tweeter... IMHO😀

Just tested the fullrange FR125S - it sounded quite nice... with a small series inductor 😀

 

[Cal Weldon]

An FR125 with a choke?

Sounds like the WR125.😉

 

[tinitus]

Its a very small choke

Quite funny - on paper it seems that WR125 actually has lower voice coil inductance (Le) than FR125 ??

Carlos, I would not go beond 4khz with your vifa, probably a little less

Thanks. I'm trying to keep this simple though and I got enough holes in my little cabinet 😀
