Hello, first, my English is very bad.
How are you?, i'm fine.
I'm from Argentina and it is sistem:
Yamaha RXV 650, DVD Pionner 578, CSi25 from center channel, RT55's from front channel's, Yamaha YST SW 90 (sub) and (it is my question) JBL E10 (from old system) from surround speakers.
The sound of Polk's speakers is beautifull.
I want to change the E 10 but are between FX300 (or 500) or R15.
What make us?
Excuse my bad lenguage.
