Amps for Paradigm Persona 3f

Our setup is with Wireworld  Platinium or Gold int. We are using Wireworld Silver speaker cables. 

Power conditioner Isotek or Audio Magic.

If you are ever in the NYC area please come over and hear our setup. We are remerchandising this sound room so we will have some demo cables if you need them at good prices

Georgehifi- not sure if this helps with impedance & phase angle question,
the L&R speakers in the link below are the Paradigm Persona 3f speakers-

Bit hard to tell without a complete overview of a impedance v phase graph, as they’ve only selected 3 different points to give in print, and those "could" be doctored/selected to look easy.

But with what there is to work with.

1: In the bass:
Impedance reaches a minimum of 4.42 ohms at 141 Hz and a phase angle of –60.68 degrees at 98 Hz. This could be seen as a potential problem for amps by the amp, as a EPDR load of around 2.5ohm to 3ohms in the bass

2: In the Highs:
With 3.49 ohms at 16.1 kHz with phase angle of –53.22 degrees at 18khz this is a potential problem for amps, as it could equate to around an EPDR load as seen by the amp of around 2 to 2.5ohms in the highs

There’s nothing measured for midrange frequencies.

With what we’ve got here, because the 3f’s are 89db efficient, a 100w or higher amp into 8ohm will do. But it looks to me from the above measurements it’s a speaker that need a bit current also from the amp, that is solid state amps that can "almost" double their wattage from 8ohms to 4ohms to 2ohms would be great. EG: 100w 200w 400w. Even though they may work, I’d stay away from tubes with these, if you want the very best out of them.


Cheers George

Thanks George-helps narrow the field,

OEM- I appreciate the specifics of your system & experience. I think it would be easy to slip into overly analytical detail with the 3fs.
