Paradigm persona 9H

[Purité Audio]

Looks rougher than I would have expected.

it does sting a bit

I went to hear the 9H and borrowed the smaller ones,

About $50,000??? Really? holy...

Interesting...I heard these at my local Paradigm dealer and I was blown away. But....I feel like everything sounds better at the dealer, and I have no clue what they were using to drive them. For sure they will need some muscle behind them with that impedance.

$35,000, still.

Assuming it's identical performance to the unpowered version ($5000) other than the hidden woofers, if assuming awesome work by ARC, it may sound pretty good, as the directivity is good, despite the terrible FR.

Please tell me you are joking.

 

[MZKM]

Please tell me you are joking.

The directivity seems consistent off-axis, the FR is just terrible.

35,000 pounds isn’t it?

 

[MZKM]

35,000 pounds isn’t it?

It’s also $35,000 USD.

I read that. I don't understand how you can extrapolate that it may sound pretty good.

 

[tuga]

Rings like a proverbial bell

 

[A800]

Looks almost like a Bose FR.

oh ok. Didn't know that...


still though! lol...

I see no ringing. That 20kHz peak is due to the peak on-axis, there is no ringing.

Pretty good directivity; still not amazing.

Pretty good directivity; still not amazing.

Could you please post the link from where this measurement comes from?

 

[tuga]

I see no ringing. That 20kHz peak is due to the peak on-axis, there is no ringing (1kHz could decay a bit faster).

Pretty good directivity; still not amazing.

You see no ringing in the lateral response plot.

Do you see the ringing in the CSD?

 

[Daverz]

Didn't Paradigm used to care about good frequency response? Or am I confusing them with the other Canadian company, PSB?

 

[MZKM]

You see no ringing in the lateral response plot.

Do you see the ringing in the CSD?

No. Again, the CSD is not normalized, that peak at >20kHz is not ringing, it has excess SPL at time 0 so it looks like ringing. CSD plots should be normalized to showcase ringing/resonances.

 

[tuga]

No. Again, the CSD is not normalized, that peak at >20kHz is not ringing, it has excess SPL at time 0 so it looks like ringing. CSD plots should be normalized to showcase ringing/resonances.

You don't want to see the ringing in the CSD.

The peak at around 1.4kHz looks suspiciously like a breakup resonance of the midrange.

It even shows in the impedance plot.

Could it be ringing?
