If it's a modern 5+ channel AVR, then you should be able to go into the setup menu and enter your speaker configuration (which speakers you have and do not have installed, distance from listening position, etc.) or run auto room EQ (where the AVR emits test tones into a microphone you place in the listening position and automatically determines the speaker configuration). Either automatically or manually though, the Sony will provide a phantom center channel.
The main problems with not having a dedicated center speaker are inferior off-axis response and the inability to adjust the volume/tone of the center image. With a dedicated center speaker, it can be calibrated to match your front left and right speakers, even if it's another make/design.
The Primus 150 is a very decent budget speaker, but I think an inexpensive center speaker from another brand that is well designed will serve you just fine. I would definitely consider a JBL or Polk Audio center speaker as a viable solution. That, or find a Primus speaker from a North American seller who will ship internationally.
It's a Sony STR-DH700, a 7.1 7x100W AVR. It has and automatic EQ function, yes.
Finding a North American seller who ships internationally.. that would a solution, but too expensive, as the shiping costs would be quite high (in Amazon I've located 2 sellers that would ship it internationally, both charge over $70 for shiping) and, possibly, custom fees. At the end I'd get the Primus C251 for well over $200, which is definetely too much for that speaker.
You say a JBL or a Polk could be a good solution. May I ask why a Polk?
The other suggested solution (from guns&motorcycles) about selling the Primus and getting the full front stage could be a solution, but here in Europe we don't get as good deals as you in the USA and changing the whole front stage with better speakers would come to a price which, right now, I'm not willing to pay.
I think I'll just get the JBL EC25 and try it. If I like it, I'll keep it, if not I'll return it and forget about the center speaker until I can by a clearly better front stage complete with the center.
Thanks for your help!
