Paradigm Persona: what do you think?

Hi Todd,

We appreciate your enthusiasm for our speakers.  Only the 9H is sealed, along with a vibration cancelling design.  The other floor standing models have ports in the bottom - no passive radiators.  
Here is a link to our Persona Series and if you have time, please enjoy the brief  YouTube videos showing a little more in depth info about them.

We appreciate your interest and please let us know how/if we can further assist you, but you should be in capable hands at your Dealer.  
Cheers,
Chris

Not cheap, but a lot for the money

Search the site.  The Personas were the subject of several pretty contentious threads a while ago.
