Hi, this is confusing me.
Q950 has 2 powered woofers or 2 passive radiators?
@thewas ?
If it has 2 passive radiators,
then we have tweeter + midrange (Uni-Q)
And one powered woofer?
Spec states only one crossover point at 2.2kHz
Can anyone clearly breakdown the crossover design of this please
Since writing this, I now have a pair of Q900 and Q950 (these as surrounds).
Both are 2.5 way crossovers. Full range sent to the top driver, a woofer with the Uni-q. Two sets of wires, one treble to Uni-q unit and one mid and bass to woofer.
Then just bass sent to one other woofer.
Hence the crossover has 3 outputs. One is just bass, one mid and bass and one treble.
Now you can see why it quotes two crossover points in the KEF manuals?
From memory the crossover points are slightly different between the models. Understandable as they have quite different separation of sections inside.
In addition, both models have two radiators. (So they appear to have 4 eight inch drivers from the front).
However, I was wrong before. The Q900 has the 2nd driver down as a bass woofer. The Q950 uses the 3rd driver down as a bass woofer.
Also, perhaps relevant. The Q950 has one connection at the rear. The Q900 has bi-wire.
It took a lot of listening to decide whether to use the Q950 as fronts or surrounds. I wouldn't call them an "upgrade" I would call them different.
If you want some wishy washy audiophile speak... the Q950 have better control and subtlety. But they lose some soundstage, impact and weight.
I'd choose the Q950 for Miles Davis, Supertramp or Joni Mitchell. I'd choose the Q900 for The Prodigy, Jean Michel Jarre or Kansas.
As most of our listening is TV and not music, we wanted more impact upfront.
Especially considering the growing trend in TV dramas and films to use surrounds for music in the soundtrack!
